C#使用Winfrom编程时的注意事项

C#让窗体不能被修改大小

FormBorderStyle = FormBorderStyle.FixedSingle;

让窗体在屏幕中心显示：

this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;

关闭最大化功能：

this.MaximizeBox = false;

关闭最小化功能：

this.MinimizeBox = false;

让组件可以被多线程修改：

System.Windows.Forms.Control.CheckForIllegalCrossThreadCalls = false;

发送httpd请求：

·HttpWebRequest req = (HttpWebRequest)WebRequest.Create(new Uri(@"url地址"));
   req.Method = "协议";
   req.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:62.0) Gecko/20100101 Firefox/62.0";
   req.ContentType = "application/x-www-form-urlencoded";
   req.Accept = "application/json";
   req.Referer = "http://www.kdjz.com/";
   string result = "";

   StringBuilder builder = new StringBuilder();
   builder.AppendFormat("{0}={1}", "phone", textBox1.Text);
   builder.Append("&");
   builder.AppendFormat("{0}={1}", "password", textBox2.Text);

   byte[] data = Encoding.UTF8.GetBytes(builder.ToString());
   req.ContentLength = data.Length;
   using (Stream reqStream = req.GetRequestStream())
   { reqStream.Write(data, 0, data.Length); reqStream.Close(); }
   HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
   Stream stream = resp.GetResponseStream();
   //获取响应内容         
   using (StreamReader reader = new StreamReader(stream, Encoding.UTF8))
   { result = reader.ReadToEnd(); }

开启多线程执行函数：

Thread thread1 = new Thread(new ThreadStart(StartSomeWorkFromUIThread));
                Thread thread2 = new Thread(new ThreadStart(GetMessage));
                thread1.IsBackground = true;
                thread1.Start();

定义动态string数组：

private List<string> Have_Gotton_User_Name = new List<string>();
