俗话说，一个好汉十个帮，众人拾柴火焰高等都说明一个道理，有更多的资源，更丰富的积累，都是助你走向成功，走向顶峰的推动力。
本篇的公用类库的介绍主题是程序开发中常用到的一些辅助类，在帮助文档中归类到其他目录下面，本篇主要介绍有注册表的操作、反射操作、正则表达式操作、Zip压缩操作、AD操作、字符串Unicode转换操作等常见但有些凌乱的类库。
本篇继续继续整理优化已有的共用类库，并继续发表随笔介绍公用类库的接口方法以及详细使用操作，力求给自己继续优化，积攒更丰富的公用类库资源，加深了解的同时，也给大家展现公用类库好的方面。
1、注册表操作辅助类RegistryHelper，通过默认指定注册表的前缀路径，减少调用复杂性。
1）辅助类提供的方法接口如下所示：

/// <summary>    
/// 获取注册表项的值。如果该键不存在，则返回空字符串。    
/// </summary>    
/// <param name="key">注册表键</param>    
/// <returns>指定键返回的值</returns>    
public static string GetValue(string key)    

/// <summary>    
/// 获取注册表项的值。如果该键不存在，则返回空字符串。    
/// </summary>    
/// <param name="softwareKey">注册表键的前缀路径</param>    
/// <param name="key">注册表键</param>    
/// <returns>指定键返回的值</returns>    
public static string GetValue(string softwareKey, string key)    

/// <summary>    
/// 获取注册表项的值。如果该键不存在，则返回空字符串。    
/// </summary>    
/// <param name="softwareKey">注册表键的前缀路径</param>    
/// <param name="key">注册表键</param>    
/// <param name="rootRegistry">开始的根节点（Registry.CurrentUser或者Registry.LocalMachine等）</param>    
/// <returns>指定键返回的值</returns>    
public static string GetValue(string softwareKey, string key, RegistryKey rootRegistry)    

/// <summary>    
/// 保存键值到注册表    
/// </summary>    
/// <param name="key">注册表键</param>    
/// <param name="value">键的值内容</param>    
/// <returns>如果保存成功返回true，否则为false</returns>    
public static bool SaveValue(string key, string value)    

/// <summary>    
/// 保存键值到注册表    
/// </summary>    
/// <param name="softwareKey">注册表键的前缀路径</param>    
/// <param name="key">注册表键</param>    
/// <param name="value">键的值内容</param>    
/// <returns>如果保存成功返回true，否则为false</returns>    
public static bool SaveValue(string softwareKey, string key, string value)    

/// <summary>    
/// 保存键值到注册表    
/// </summary>    
/// <param name="softwareKey">注册表键的前缀路径</param>    
/// <param name="key">注册表键</param>    
/// <param name="value">键的值内容</param>    
/// <param name="rootRegistry">开始的根节点（Registry.CurrentUser或者Registry.LocalMachine等）</param>    
/// <returns>如果保存成功返回true，否则为false</returns>    
public static bool SaveValue(string softwareKey, string key, string value, RegistryKey rootRegistry)   

#endregion   

#region 自动启动程序设置    

/// <summary>    
/// 检查是否随系统启动    
/// </summary>    
/// <returns></returns>    
public static bool CheckStartWithWindows()    

/// <summary>    
/// 设置随系统启动    
/// </summary>    
/// <param name="startWin"></param>    
public static void SetStartWithWindows(bool startWin)   

#endregion

2）辅助类的使用例子代码如下所示

private void btnRegistryHelper_Click(object sender, EventArgs e)    
{    
    string result = string.Empty;    
    result += "使用RegistryHelper注册表访问辅助类：" + "\r\n";    

    string softwareKey = @"Software\DeepLand\OrderWater";    
    bool sucess = RegistryHelper.SaveValue(softwareKey, "Test", DateTime.Now.ToString());    
    if (sucess)    
    {    
        result += RegistryHelper.GetValue(softwareKey, "Test") + "\r\n";    
    }    

    RegistryHelper.SaveValue(softwareKey, "Test", "测试内容", Microsoft.Win32.Registry.LocalMachine);    
    result += RegistryHelper.GetValue(softwareKey, "Test", Microsoft.Win32.Registry.LocalMachine);     

    MessageUtil.ShowTips(result);    
}

演示代码效果如下所示。

2、反射操作辅助类ReflectionUtil，如获取或设置字段、属性的值等反射信息。
本辅助类主要是用来方便实现反射操作辅助类，如获取或设置字段、属性的值等反射信息。在通用的赋值操作（属性或者字段）、执行方法或者需要获取特定对象属性的时候，就需要大量用到反射操作。
1）辅助类提供的方法接口如下所示：

#region 属性字段设置    
/// <summary>    
/// 绑定标识    
/// </summary>    
public static BindingFlags bf = BindingFlags.DeclaredOnly | BindingFlags.Public |

2）辅助类的使用例子代码如下所示，例子是Socket框架里面用来反序列化对象的操作，通过反射把字符串的值赋值到对象里面。

/// <summary>    
/// 转换Socket接收到的信息为对象信息    
/// </summary>    
/// <param name="data">Socket接收到的信息</param>    
public BaseEntity(string data)    
{    
    string[] dataArray = NetStringUtil.UnPack(data);    
    if (dataArray != null && dataArray.Length > 0)    
    {    
        int i = 0;    
        FieldInfo[] fieldArray = ReflectionUtil.GetFields(this);    
        if (fieldArray == null || dataArray.Length != fieldArray.Length)    
        {    
            throw new ArgumentException("收到的信息和字段信息不一致");    
        }    

        if (fieldArray != null)    
        {    
            foreach (FieldInfo info in fieldArray)    
            {    
                string strValue = dataArray[i++];    
                try   
                {    
                    if (!string.IsNullOrEmpty(strValue))    
                    {    
                        ReflectionUtil.SetField(this, info.Name, strValue);    
                    }    
                }    
                catch (Exception ex)    
                {    
                    Communication.Model.Log.WriteError(string.Format("转换数据发生错误:{0}【{1}】",    
                        ex.Message, data));    
                    break;    
                }    
            }    
        }    
    }    
}

例如两个对象的属性基本相同，可以进行对象的拷贝赋值。

#region 表结构一样，复制相关的内容    
PilotInfo pilotInfo = BLLFactory<Pilot>.Instance.FindByID(txtPilot.PilotID);    
if (pilotInfo != null)    
{    
    PropertyInfo[] outPropertyArray = ReflectionUtil.GetProperties(info);    
    PropertyInfo[] pilotPropArray = ReflectionUtil.GetProperties(pilotInfo);    
    if (pilotPropArray != null && outPropertyArray != null)    
    {    
        foreach (PropertyInfo propInfo in pilotPropArray)    
        {    
            try   
            {    
                object value = ReflectionUtil.GetProperty(pilotInfo, propInfo.Name);    
                foreach (PropertyInfo outInfo in outPropertyArray)    
                {    
                    if (outInfo.Name == propInfo.Name)    
                    {    
                        ReflectionUtil.SetProperty(info, propInfo.Name, value);    
                    }    
                }    
            }    
            catch (Exception ex)    
            {    
            }    
        }    
    }    
}   
#endregion

3、程序集反射创建对象实例辅助类 Reflect

本辅助类主要是用来方便实现程序集反射创建对象实例的操作。该程序集反射春节对象实例的操作，在我的WInform开发框架中用于对象的创建操作。

1）辅助类提供的方法接口如下所示：

/// <summary>    
/// 程序集反射创建对象实例辅助类    
/// </summary>    
/// <typeparam name="T">对象类型</typeparam>    
public class Reflect<T> where T : class     
{    
    /// <summary>    
    /// 缓存的hash表集合    
    /// </summary>    
    public static Hashtable ObjCache    

    /// <summary>    
    /// 根据参数创建对象实例    
    /// </summary>    
    /// <param name="sName">对象全局名称</param>    
    /// <param name="sFilePath">文件路径</param>    
    /// <returns></returns>    
    public static T Create(string sName, string sFilePath)    

    /// <summary>    
    /// 根据参数创建对象实例    
    /// </summary>    
    /// <param name="sName">对象全局名称</param>    
    /// <param name="sFilePath">文件路径</param>    
    /// <param name="bCache">缓存集合</param>    
    /// <returns></returns>    
    public static T Create(string sName, string sFilePath, bool bCache)    

    /// <summary>    
    /// 创建程序集对象    
    /// </summary>    
    /// <param name="sFilePath">文件路径</param>    
    /// <returns></returns>    
    public static Assembly CreateAssembly(string sFilePath)    
}

2）辅助类的使用例子代码如下所示（摘自我的Winform开发框架里面的对象反射操作）。在下面的例子中，通过传入的类型T，在程序集中构造制定类型的对象，并放入到缓存当中。

public class BLLFactory<T> where T : class   
{    
    private static Hashtable objCache = new Hashtable();    
    private static object syncRoot = new Object();    

    public static T Instance    
    {    
        get   
        {    
            string CacheKey = typeof(T).FullName;    
            T bll = (T)objCache[CacheKey];　 //从缓存读取      
            if (bll == null)    
            {    
                lock (syncRoot)    
                {    
                    if (bll == null)    
                    {    
                        bll = Reflect<T>.Create(typeof(T).FullName, "WHC.WareHouseMis"); //反射创建，并缓存    
                        //bll = Reflect<T>.Create(typeof(T).FullName, System.Reflection.Assembly.GetExecutingAssembly().GetName().Name); //反射创建，并缓存    
                        objCache.Add(typeof(T).FullName, bll);    
                    }    
                }    
            }    
            return bll;    
        }    
    }    
}

4、正则表达式辅助类 CRegex
本辅助类主要是用来方便实现对正则表达式的封装使用，通过利用该类库，可以简化C#对正则表达式的操作，但不能替代掌握正则表达式的知识。正则表达式可以通过The Reguator等正则表达式调试工具来验证编写的表达式，基本的操作是匹配，替换，分割等，调试工具界面如下：

1）软件包含下面基础通用的操作正则表达式方法的定义，以及一些封装好的正则表达式操作，如获取HTML标题、Body等内容。

/// <summary>    
/// 内容是否匹配指定的表达式    
/// </summary>    
/// <param name="sInput">输入内容</param>    
/// <param name="sRegex">表达式字符串</param>

public static string GetText(string sInput, string sRegex, string sGroupName)    

/// <summary>

/// <param name="iGroupIndex">分组序号, 0代表不分组</param>    
public static string Replace(string sInput, string sRegex, string sReplace, int iGroupIndex)    

/// <summary>

2）辅助类的使用例子代码如下所示

//压缩解压缩文本内容    
string zippedContent = GZipUtil.Compress("wuhuacong");    
string original = GZipUtil.Decompress(zippedContent);    

GZipUtil.Compress(Application.StartupPath, Application.StartupPath, "cityroad.zip");    
GZipUtil.Decompress(Application.StartupPath, Path.Combine(Application.StartupPath, "cityroad"), "cityroad.zip");    

MessageUtil.ShowTips("操作完成");

6、字符串Unicode转换操作辅助类 UnicodeHelper。

public static string GBToUnicode(string str)    

/// <summary>    
/// 转换一个字符，输入如"Π"中的"03a0"    
/// </summary>    
/// <param name="unicodeSingle">待转换字符串</param>

/// </summary>    
/// <param name="str">待转换字符串</param>    
/// <returns></returns>    
public static string UnicodeToGB(string str)

2）辅助类的使用例子代码如下所示

private void btnUnicodeHelper_Click(object sender, EventArgs e)    
{    
    string str = "\u821e\u7fbd\u6e05\u548c \u5c71\u7f8a\u4e4b\u89d2";    
    string test = UnicodeHelper.UnicodeToString(str);    
    string result = test + "\r\n";    
    result += UnicodeHelper.StringToUnicode(test) + "\r\n";    

    MessageUtil.ShowTips(result);    
}
