公布源代码，新程序，分析网页，取指定值，并存储，操纵网页，填值，模拟点击，容错，发送。
为了在朋友圈里多加些人，我就写了这个程序，将成员列表里的用户名提取出来，再写到dataview,然后填到textbox，程序自动点击“邀请”。用到了webbrowser，分析HTML，操作网页上的一些control，比如，点击，按钮。填入内容。
代码不多，一看就明白，就不多写了。
源码如下：

using System.Data;

using System.Text;
using System.Windows.Forms;

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
//根据Url地址得到网页的html源码
private string GetWebContent(string Url)
{
string strResult = "";
try
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);
//声明一个HttpWebRequest请求
request.Timeout = 30000;
//设置连接超时时间
