WebRequest 的使用

 读取服务端数据:

WebRequest req = WebRequest.Create(tbURL.Text);
            WebResponse res = req.GetResponse();
            Stream ReceiveStream = res.GetResponseStream();
            Encoding ecode = Encoding.GetEncoding("utf-8");
            StreamReader sr = new StreamReader(ReceiveStream,ecode);
            Char[] ReadBuffer = new char[256];
            int nCount = sr.Read(ReadBuffer,0,256);
            while(nCount>0)
            ...{
                string str = new string(ReadBuffer,0,nCount);
                tbContent.Text += str;
                nCount = sr.Read(ReadBuffer,0,256);
            }

 

向服务器端写数据:

WebRequest req = WebRequest.Create(tbURL.Text);
            req.Method = "POST";
            req.ContentType="application/x-www.form-urlencoded";

            byte[] bData = null;
            bData = Encoding.UTF8.GetBytes(tbPostData.Text);
            req.ContentLength = bData.Length;
            Stream newStream = req.GetRequestStream();
            newStream.Write(bData,0,bData.Length);
            newStream.Close();
