通过HttpWebRequest来绑定WebBrowser

private string GetHTMLstring(string url)

{

HttpWebRequest httpWebRequest;

HttpWebResponse webResponse;

Stream stream;

byte[] byteRequest = { };

httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(url); //加载URL

httpWebRequest.ContentType = "application/x-www-form-urlencoded";

httpWebRequest.Method = "Post";

httpWebRequest.ContentLength = byteRequest.Length; //设置Header

stream = httpWebRequest.GetRequestStream();

stream.Write(byteRequest, 0, byteRequest.Length); //POST信息

stream.Close();

webResponse = (HttpWebResponse)httpWebRequest.GetResponse(); //收到应答

StreamReader sr = new StreamReader(webResponse.GetResponseStream(), System.Text.Encoding.Default);

return (sr.ReadToEnd());

}

这种方式获取网页的话有个问题，就是页面的按钮失效了，该怎么解决呢：

private void button1_Click(object sender, EventArgs e)

{

string html = "";

html += " <html> <head> </head> <body>";

html += " <input value=\\"OK\\" type=\\"button\\" onclick=\\"alert('OK');\\" name=\\"OK\\" id=\\"OK\\" />";

html += " </body> </html>";

webBrowser1.DocumentText = html;

}

private void button2_Click(object sender, EventArgs e)

{

HtmlDocument htmlDocument = webBrowser1.Document;

HtmlElement htmlElement = htmlDocument.GetElementById("OK");

htmlElement.InvokeMember("click");

}
