操作IE浏览器，模拟用户登录，首先需要两个程序集：shdocvw.dll和mshtml.dll；

新建项目将程序集引用到项目中；

代码如下：

  1 using System;
  2 using System.Collections.Generic;
  3 using System.Linq;
  4 using System.Text;
  5 using System.Threading.Tasks;
  6 using mshtml;
  7 using SHDocVw;
  8 using System.Threading;
  9 using System.Diagnostics;
 10 
 11 namespace StudyPrograms
 12 {
 13     class Program
 14     {
 15         static AutoResetEvent documentComplete = new AutoResetEvent(false);
 16  
 17         static void Main(string[] args)
 18         {
 19             Console.WriteLine(DateTime.Now.ToString() + " 开始");
 20             InternetExplorer ie = GetInternetExplorer();
 21             if (ie != null)
 22             {
 23                 Run(ie);
 24             }
 25             Console.WriteLine(DateTime.Now.ToString() + " 结束");
 26         }
 27 
 28         private static InternetExplorer GetInternetExplorer()
 29         {
 30             InternetExplorer ie = null;
 31             Console.WriteLine(DateTime.Now.ToString() + " 加载IE实例");
 32 
 33             //查找是否有打开的IE进程窗口，如果已经包含CSDN登录页，则得到此进程
 34             Process[] processes = Process.GetProcesses();
 35             Process process = null;
 36             foreach (Process p in processes)
 37             {
 38                 if (string.Compare(p.ProcessName, "iexplore", true) == 0)
 39                 {
 40                     if (p.MainWindowTitle.IndexOf("CSDN 用户登录") >= 0) // CSDN 用户登录 - Windows Internet Explorer
 41 
 42                     {
 43                         process = p;
 44                         break;
 45                     }
 46                 }
 47             }
 48 
 49             //如果没有则启动IE实例
 50             if (process == null)
 51             {
 52                 process = Process.Start("iexplore.exe", "about:blank");

150

152         }
153 
154         private static void ie_DocumentComplete(object pDisp, ref object URL)
155         {
156             documentComplete.Set();
157         }
158     }
159 }

使用前关闭所有IE浏览器，然后运行，否则会出现异常，目前没解决
