如何在winform中动态添加或删除控件，多谢了

[threenewbee]

Controls.Add(new Label() { Size = new Size(100, 100), Text = "I'm new", name = "newlabel" });

Controls.Remove("newlabel");

[caoqinghua]

//添加控件
TextBox txt = new TextBox();
txt.Text = "我是自动添加的";
txt.Location = new Point(10, 10);
this.Controls.Add(txt);
//移除控件
this.Controls.Remove(txt);
txt.Dispose();

		private void Form1_Load(object sender, EventArgs e)
		{
			Button[] buttons = new Button[3];
			for (int i = 0; i < buttons.Length; i++)
			{
				buttons[i] = new Button();
				buttons[i].Name = "button" + i;
				buttons[i].Text = buttons[i].Name;
				buttons[i].Location = new Point(10, 30 * i);
				buttons[i].Click += new EventHandler(Buttons_Click);
			}
			this.Controls.AddRange(buttons);
		}
		void Buttons_Click(object sender, EventArgs e)
		{
			this.Text = (sender as Button).Text;
		}

移除控件用this.Controls.Remove(控件);//不一定是this，也可以是其他父容器控件

Panel pnl = new Panel();
TextBox textBox3 = new TextBox();
textBox3.BackColor = Color.White;
textBox3.Location = new System.Drawing.Point(481, 6);
textBox3.Name = "textBox3";
textBox3.Size = new System.Drawing.Size(118, 21);
textBox3.TabIndex = 5;
textBox3.ReadOnly = true;
textBox3.Text = OperatorName;
pnl.Controls.Add(textBox3);
this.pnlMessage.Controls.Add(pnl);


移除
for (int i = 0; i < flowLayoutPanel.Controls.Count; i++)
{
if (flowLayoutPanel.Controls[i].Name == txtFilePath.Text)
{
flowLayoutPanel.Controls.Remove(flowLayoutPanel.Controls[i]);
txtFilePath.Text = "";
return;
}
}

this.Controls.Clear();
//移除所有

可以参考　设计器生成的　designer.cs
删除就是　Controls.Remove

我是这样子去实现的，动态生成的时候给加个右键菜单，然后要删除时右键菜单响应。

 private void 删除ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            pictureBox1.Controls.Remove(contextMenuStrip1.SourceControl);
            contextMenuStrip1.SourceControl.Dispose();
            pictureBox1.Refresh();
        }

希望对后来看到的人有用

移除后最好dispose掉
