vb.net 如何动态彻底删除控件

晕,你把有用的控件选中,然后ctrl+x剪切,再全选窗体内控件,删除!删完了再粘贴!

for each 循环删除控件(vb.net 2003)

因为你在删除的过程中,控件数量改变,导致循环次数不准确,所以才会不完全删除控件

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using System.Xml;

namespace WindowsApplication14

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)

{

}

private void Form1_Load(object sender, EventArgs e)

{

setLabel(5);

}

private void setLabel(int num)

{

for (int i = 0; i num; i++)

{

Label testLbl = new Label();

testLbl.Text = i.ToString();

this.Controls.Add(testLbl);

testLbl.Top = i * 50;

testLbl.Left = 10;

}

}

private void button1_Click(object sender, EventArgs e)

{

clearLabel(this);

}

private void clearLabel(Control container)

{

for (int i = container.Controls.Count; i 0;i-- )

{

Label lbl = container.Controls[i-1] as Label;

container.Controls.Remove(lbl);

}

}

private void button2_Click(object sender, EventArgs e)

{

setLabel(5);

}

}

}
