一、 以lable为例：               在Form中放一个控件，让其在启动和动态改变窗口大小时始终居中             int gLeft = this.Width / 2 - lable1.Width / 2; //this指Form             int gTop = this.Height / 2 - lable1.Height / 2;               lable1.Location = new Point(gLeft, gTop);    二、动态创建控件并找到或者删除控件               1、 以Lable为例创建控件：                           Label lbl = new Label();                         lbl.Name = "lblNum" + m;                         lbl.AutoSize = true;                         lbl.BackColor = System.Drawing.Color.Transparent;                         lbl.Font = new System.Drawing.Font("宋体", 36F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(134)));                         lbl.ForeColor = System.Drawing.Color.White;                         lbl.Location = new System.Drawing.Point(lable1.Location.X - 150, 29);                         lbl.TextAlign = System.Drawing.ContentAlignment.TopCenter;                         lbl.Anchor = System.Windows.Forms.AnchorStyles.Top;                        // this.Controls.Add(lbl);窗体中添加控件                         this.groupBox2.Controls.Add(lbl);//groupBox2中添加控件                              2、以Lable为例删除控件：             if (this.groupBox2.Controls.ContainsKey("lable2") == true)             {                 this.groupBox2.Controls.RemoveByKey("lable2");             }                      3、找到控件并对其赋值                        Control[] control = this.Controls.Find("lable1" ，true);                if (control.Length == 1 && control[0] is Label)               {                       (control[0] as Label).Text =“hello”；                 }
