• WebClient Get

• public string WebClientGet(string url)
  {
      WebClient client = new WebClient();
      client.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");

      string result = reader.ReadToEnd();
      stream.Close();
      reader.Close();
      return result;
  }

• public string GetStr(string data)
  {
  　　string url = "";
  　　byte[] postData = Encoding.UTF8.GetBytes(data);
  　　WebClient webClient = new WebClient();
  　　webClient.Headers.Add("Content-Type", "application/x-www-form-urlencoded");//采取POST方式必须加的header，如果改为GET方式的话就去掉这句话即可 
  　　byte[] responseData = webClient.UploadData(url, "POST", postData);//得到返回字符流
  
  　　string getStr = Encoding.UTF8.GetString(responseData);//解码
  　　return getStr;
  }
