/// </summary>
public void ClearRecipient()
/// <summary>
/// 发送邮件
/// </summary>
public bool SendEmail()
2)辅助类EmailHelper的使用例子代码如下所示
EmailHelper email = new EmailHelper("smtp.163.com", "wuhuacong2013@163.com", "password");
email.Subject = "伍华聪的普通测试邮件";
email.Body = string.Format("测试邮件正文内容");
email.IsHtml = true;
email.From = "wuhuacong2013@163.com";
email.FromName = "wuhuacong2013";
email.AddRecipient("6966254@qq.com");
try
{
bool success = email.SendEmail();
MessageUtil.ShowTips(success ? "发送成功" : "发送失败");
}
catch (Exception ex)
{
MessageUtil.ShowError(ex.Message);
}
3)如果使用发送附件、发送嵌入图片(正文中有图片显示内容的)方式,则例子代码如下所示。
EmailHelper email = new EmailHelper("smtp.163.com", "wuhuacong2013@163.com", "password");
email.Subject = "伍华聪的图片附件测试邮件";
string embedFile = Path.Combine(Application.StartupPath, "cityroad.jpg");
email.Body = string.Format("测试邮件正文内容<img src=\"{0}\" title='测试图片' /> ", embedFile);
email.IsHtml = true;
email.From = "wuhuacong2013@163.com";
email.FromName = "wuhuacong2013";
email.AddRecipient("6966254@qq.com");
email.AddAttachment(Path.Combine(Application.StartupPath, "ringin.wav"));//.AddAttachment("C:\\test.txt");
try
{
bool success = email.SendEmail();
MessageUtil.ShowTips(success ? "发送成功" : "发送失败");
}
catch (Exception ex)
{
MessageUtil.ShowError(ex.Message);
}
2、获取网页数据辅助类库 HttpHelper。
实现效果
1) 本辅助类主要是用来方便实现获取网页数据的操作,可以通过GET、POST方式获取网页内容,获取验证码等图片资源,是网络编程不可或缺的强大辅助类库。
2) 该辅助类库在我的QQ搜通天系列软件、QQ群成员提取工具、易博搜搜等网络应用软件上,辅助类主要是用于网页数据采集和分析操作。

/// <returns>解码结果</returns>
public static string HtmlDecode(string str)
#endregion
2)辅助类HttpHelper的使用例子代码如下所示,下面的是最为简单的获取页面内容的操作。
public void GetQQLog()
{
string qq = this.txtQQ.Text;
string json = "";
string url = string.Format("http://b.qzone.qq.com/cgi-bin/blognew/blog_get_titlelist?direct=1&numperpage=100&uin={0}", qq);
HttpHelper helper = new HttpHelper();
helper.Encoding = Encoding.Default;
json = helper.GetHtml(url);
..............
}
实际操作可能更多的是要记录Cookie信息,方便下一次的调用,还有可能需要获取验证码等等,复杂一点的例子代码如下所示。
string uin = e.Argument.ToString();
HttpHelper httpHelper = new HttpHelper();
string refUrl = "http://qzone.qq.com/";
string url = string.Format("http://ptlogin2.qq.com/check?uin={0}&appid=46000101&r=0.5454333601416937", uin);
string checkHtml = httpHelper.GetHtml(url, Portal.gc.cookieZone, refUrl);
//ptui_checkVC('1','56443c908b8be83dc4435e253e6b43ad99eab4fe0846930d');
Regex re = new Regex("ptui_checkVC\\('\\d+','(.*?)'\\);", RegexOptions.IgnoreCase | RegexOptions.Singleline | RegexOptions.IgnorePatternWhitespace);
Match mc = re.Match(checkHtml);
if (!mc.Success)
{
return;
}
string vc_type = re.Matches(checkHtml)[0].Groups[1].Value;
string imageUrl = string.Format("http://captcha.qq.com/getimage?aid=46000101&r=0.2758570793854393&uin={0}&vc_type={1}", uin, vc_type);
using (Stream s = httpHelper.GetStream(imageUrl, Portal.gc.cookieZone))
{
if (s == null)
{
MessageExUtil.ShowWarning("获取登陆码错误,请检查您的网络!");
return;
}
e.Result = Image.FromStream(s);
}
上面的操作都是使用GET方式获取页面内容或者数据的,另外还有一种方式就是使用POST方式提交数据,并获取页面内容的,如下例子所示。
#region 构造提交参数
StringBuilder sb = new StringBuilder();
sb.AppendFormat("callCount=1");
sb.AppendFormat("&page=/{0}/members/", urlName);
sb.AppendFormat("&httpSessionId=");
sb.AppendFormat("&scriptSessionId=D4DAC4AD9C3BF9B71C82802BDDBA0C25369");
sb.AppendFormat("&c0-scriptName=CircleBean");
sb.AppendFormat("&c0-methodName=getNewCircleUsers");
sb.AppendFormat("&c0-id=0");//保留字符
sb.AppendFormat("&c0-param0=number:{0}", circleId);//11
sb.AppendFormat("&c0-param1=number:{0}", pageSize);//数量
sb.AppendFormat("&c0-param2=number:{0}", pageSize * i);//0,30,60
sb.AppendFormat("&c0-param3=boolean:true");
sb.AppendFormat("&batchId={0}", i);
i++;
//callCount=1
//page=/dnkxin/members/
//httpSessionId=
//scriptSessionId=D4DAC4AD9C3BF9B71C82802BDDBA0C25369
//c0-scriptName=CircleBean
//c0-methodName=getNewCircleUsers
//c0-id=0
//c0-param0=number:15057111 //(<body onload="MembersPage.init('15057111', '/style/pinkstar/','http://blog.163.com','')">)
//c0-param1=number:10
//c0-param2=number:0
//c0-param3=boolean:true
//batchId=0
#endregion
string content = "";
try
{
httpHelper.ContentType = "text/plain";
content = httpHelper.GetHtml(url, cookie, sb.ToString(), true, refUrl);//使用Post方式提交内容,并返回页面结果
re = new Regex(circleReg.ToString(), RegexOptions.IgnoreCase | RegexOptions.Singleline | RegexOptions.IgnorePatternWhitespace);
mc = re.Match(content);
}
catch (Exception ex)
{
LogTextHelper.WriteLine(ex.ToString());
break;
}
下面是一些具体应用的例子截图,主要就是通过该辅助类获取、分析网页的处理结果。
3、管理文档服务器类,提供文件上传、下载、删除等功能辅助类 FileServerManage。
实现效果
1) 本辅助类主要是用来方便实现管理文档服务器类,提供文件上传、下载、删除等功能。 不过注意,由于IIS操作限制,可能一些后缀名的文件不支持访问。
2)FileServerManage 主要是通过IIS网站方式上传管理文件附件的,要使用该辅助类库的功能,需要为指定的目录(一般在文件服务器上一个目录)建立一个虚拟网站,指定端口等参数,该辅助类库的构造函数,使用的是虚拟网站的URL地址以及文件服务器的登录账号和密码(本机则使用本机的账号密码)。 3)另外使用IIS作为文件上传操作,除了需要用到当前机器的账号密码登录外,还需要在IIS管理中开通/启用WebDev的功能。
实现代码
1)辅助类提供的方法源码如下所示:
/// <summary>
/// 构造函数
/// </summary>
public FileServerManage()
/// <summary>
/// 构造函数

/// </summary>
/// <param name="fileUrl">上传地址</param>
/// <param name="fileName">上传文件名称,可包含文件夹(test/test.txt)</param>
/// <returns>bool[true:成功,false:失败]</returns>
public bool UploadFile(string fileUrl, string fileName)
/// <summary>
/// 删除文件
/// </summary>
/// <param name="fileName">文件名称,可包含文件夹(test/test.txt)</param>
/// <returns>bool[true:成功,false:失败]</returns>
public bool DeleteFile(string fileName)
/// <summary>

/// </summary>
/// <param name="fileName">文件名称,可包含文件夹(test/test.txt)</param>
/// <returns>bool[true:存在,false:否]</returns>
public bool IsFileExist(string fileName)
/// <summary>
/// 通过HttpResponse方式读取文件,Web开发才可以使用
/// </summary>
/// <param name="newFileName">新文件名称,可包含文件夹(test/test.txt)</param>
/// <param name="oldFileName">原文件名称</param>
/// <returns></returns>
public string ReadFile(string newFileName, string oldFileName)
/// <summary>
/// 读取服务器文件到字节数据中
/// </summary>
/// <param name="fileName">文件名称,可包含文件夹(test/test.txt)</param>
/// <returns></returns>
public byte[] ReadFileBytes(string fileName)
2)辅助类FileServerManage的使用例子代码如下所示
private void btnWebFile_Click(object sender, EventArgs e)
{
WHC.OrderWater.Commons.Web.FileServerManage file = new WHC.OrderWater.Commons.Web.FileServerManage("http://192.168.1.30:8009", "administrator", "123456789");
try
{
//上传文件
bool first = false;
using (FileStream fs = new FileStream("C:\\test.txt", FileMode.Open))
{
first = file.UploadFile(fs, "test.txt");
}
//利用子目录上传,需要服务器手动创建目录
bool second = file.UploadFile("C:\\test.txt", "Bridge/test.txt");
MessageUtil.ShowTips(string.Format("第一次上传:{0} 第二次上传{1}", first, second));
byte[] fileBytes = file.ReadFileBytes("test.txt");
if (fileBytes != null)
{
MessageUtil.ShowTips(string.Format("File Bytes:{0}", fileBytes.Length));
}
//删除文件
first = file.DeleteFile("test.txt");
bool third = file.IsFileExist("Bridge/test.txt");
second = file.DeleteFile("Bridge/test.txt");
MessageUtil.ShowTips(string.Format("删除文件:{0}、{1} 文件存在:{2}", first, second, third));
}
catch (Exception ex)
{
MessageUtil.ShowError(ex.Message);
}
}
4、网络相关操作辅助类 NetworkUtil

/// <returns></returns>
public static bool IsHostAvailable(string host)
/// <summary>
/// 在主机名解析到一个IP主机实体
/// </summary>
/// <param name="hostname">主机名</param>
/// <returns></returns>
public static IPHostEntry ResolveHost(string host)
2)辅助类NetworkUtil的使用例子代码如下所示。
private void btnNetWork_Click(object sender, EventArgs e)
{
StringBuilder sb = new StringBuilder();
sb.AppendFormat("本机IP:{0} \r\n", NetworkUtil.GetLocalIP());
sb.AppendFormat("检测本机是否联网:{0} \r\n", NetworkUtil.IsConnectedInternet());
sb.AppendFormat("www.iqid.com域名IP:{0} \r\n", NetworkUtil.ConvertDnsToIp("www.iqidi.com"));
sb.AppendFormat("本机LocalHostName:{0} \r\n", NetworkUtil.LocalHostName);
sb.AppendFormat("本机局域网IP:{0} \r\n", NetworkUtil.LANIP);
sb.AppendFormat("本机广域网IP:{0} \r\n", NetworkUtil.WANIP);
Socket socket = NetworkUtil.CreateTcpSocket();
Socket udpsocket = NetworkUtil.CreateUdpSocket();
TcpListener listen = NetworkUtil.CreateTcpListener("127.0.0.1", 9900);
listen.Start(100);
MessageUtil.ShowTips(sb.ToString());
}
5、IE代理设置辅助类 ProxyHelper。
实现效果
1) 本辅助类主要是用来方便实现IE代理设置操作。
实现代码
1)辅助类提供的方法源码如下所示:
/// <summary>
/// IE代理设置辅助类
/// </summary>
public class ProxyHelper
{
#region IE代理设置
/// <summary>
/// 让IE支持WAP
/// </summary>
public static void SetIESupportWap()
/// <summary>
/// 设置代理
/// </summary>
/// <param name="ProxyServer">代理服务器</param>
/// <param name="EnableProxy">设置代理可用</param>
/// <returns></returns>
public static string SetIEProxy(string ProxyServer, int EnableProxy)
#endregion
#region 其他操作
/// <summary>
/// 测试代理配置
/// </summary>
/// <param name="setting">代理信息</param>
/// <param name="te">测试信息</param>
public static bool TestProxy(ProxySettingEntity setting, TestEntity te)
/// <summary>
/// 代理设置
/// </summary>
/// <param name="request">Web请求</param>
/// <param name="Proxy">代理设置</param>
public static void SetProxySetting(WebRequest request, ProxySettingEntity Proxy)
#endregion
}
/// <summary>
/// 测试信息
/// </summary>
[Serializable]
public class TestEntity
{
/// <summary>
/// 测试网站地址
/// </summary>
public string TestUrl
/// <summary>
/// 测试网站Title
/// </summary>
public string TestWebTitle
/// <summary>
/// Web编码
/// </summary>
public string TestWebEncoding
}
/// <summary>
/// 代理设置
/// </summary>
[Serializable]
public class ProxySettingEntity
{
/// <summary>
/// 编号
/// </summary>
public int Id
/// <summary>
/// 代理服务器IP
/// </summary>
public string Ip
/// <summary>
/// 代理服务器端口
/// </summary>
public int Port
/// <summary>
/// 代理用户名
/// </summary>
public string UserName
/// <summary>
/// 代理密码
/// </summary>
public string Password
/// <summary>
/// 代理类型
/// </summary>
public int ProxyType
}
