groupbox文字居中_C# WinForm 控件在窗体中动态居中创建删除控件及对其赋值（转）...

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”；

}
