C＃CS发送HTTP GET请求

try
            {
                WebRequest req = WebRequest.Create("http://127.0.0.1/test/loginsso.aspx?username=admin&password=admin");
                req.Method = "POST";   //指定提交的Method，可以为POST和GET，一定要大写 
                //byte[] postData = System.Text.Encoding.GetEncoding("gbk").GetBytes("?username=admin&password=admin");//Post的数据 
                //req.ContentLength = postData.Length;
                Stream postStream = req.GetRequestStream();
                //postStream.Write(postData, 0, postData.Length);
                postStream.Close();
                WebResponse res = req.GetResponse();
                System.Text.Encoding resEncoding = System.Text.Encoding.GetEncoding("utf-8");//接收的编码 
                StreamReader reader = new StreamReader(res.GetResponseStream(), resEncoding);
                string html = reader.ReadToEnd();     //接收的Html 
                MessageBox.Show("=========" + html);
                reader.Close();
                res.Close();
            }
            catch (Exception ex)
            {
                MessageBox.Show("error");
            }

.NET接收GET发送请求

Response.ContentEncoding = Encoding.GetEncoding("UTF-8");
           string username = Request["username"];
           string password = Request["password"];
           if (username != "" && username == "admin" && password != "" && password == "admin")
           {
               Response.Write("success");
           }
           else
           {
               Response.Write("error" + Request.Url.Host);
              // Response.Redirect("http://www.g.cn");
         }

.NET接收后请求

System.Text.Encoding resEncoding = System.Text.Encoding.GetEncoding("utf-8");//接收的编码
                StreamReader reader = new StreamReader(Request.InputStream, resEncoding);
                string msg = reader.ReadToEnd();
                reader.Close();

如果 （！textBox_fileName.Text.Trim（）。等于（“” ））  
            {  
                字符串 的loadFile = textBox_fileName.Text.Trim（）;  
                字符串 文件名= loadFile.Substring（loadFile.LastIndexOf（“\\”）+1，loadFile.Length - 1 - loadFile.LastIndexOf（“ \\”））;  
                字符串 urlStr = @ “http://127.0.0.1/test/UploadFile.aspx?name=”  +文件名;  
                UploadFileBinary（的loadFile，urlStr）;  
            }  
            其他  
            {  
                字符串 alStr =  “您还没有选择文件” ;  
                MessageBox.Show（alStr， “ 系统提示” ，MessageBoxButtons.OK，MessageBoxIcon.Exclamation，MessageBoxDefaultButton.Button1）;  
            }
