模拟提交的两种用法

1、HttpWebRequest

HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("http://fanyi.baidu.com/transcontent");
Encoding encoding = Encoding.UTF8;
string param = "ie=utf-8&source=txt&query=hello&t=1327829764203&token=8a7dcbacb3ed72cad9f3fb079809a127&from=auto&to=auto";
//encoding.GetBytes(postData);
byte[] bs = Encoding.ASCII.GetBytes(param);
string responseData = String.Empty;
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = bs.Length;
using (Stream reqStream = req.GetRequestStream())
{
     reqStream.Write(bs, 0, bs.Length);
     reqStream.Close();
}
using (HttpWebResponse response = (HttpWebResponse)req.GetResponse())
{
     using (StreamReader reader = new StreamReader(response.GetResponseStream(), encoding))
     {
          responseData = reader.ReadToEnd();
     }
     Response.Write(responseData);
}

2、Webbrowser

private void Form1_Load(object sender, EventArgs e)  
{  
     this.webBrowser1.Url = new Uri("http://www.baidu.com");//指定url地址为百度首页  
}  
       
private void button1_Click(object sender, EventArgs e)  
{  
     HtmlElement searchWords = webBrowser1.Document.All["kw"];//获取百度搜索的文本框  
     HtmlElement searchButton = webBrowser1.Document.All["su"];//获取百度搜索的按钮  
     searchWords.SetAttribute("value", "guwei4037");//给百度搜索的文本框赋值  
     searchButton.InvokeMember("click");//调用百度搜索按钮的点击事件  
}
