c# WinForm 如何在坐标上添加按钮

Question

我的想法是在我点击表格的坐标上添加一个 button/custom 标记，但我不知道如何实现它。

 private void AddLogo_Click_1(object sender, EventArgs e)
    {
        
    } 
private void MapBrowser_MouseUp(object sender, MouseEventArgs e)
    {
        textBox1.Text = "X-" + e.X + "Y- " + e.Y;
        var button1 = new Button { Location = new Point(e.X, e.Y) };
       
        Controls.Add(button1);

    }

这让我每次单击表单时都能得到一个按钮，但我的想法是单击表单，然后按 addlogo 按钮向表单添加一个按钮。

Answer 1

您需要一个形式为

的变量

bool _placeButton = false;
int _xButton;
int _yButton;

然后

private void MapBrowser_MouseUp(object sender, MouseEventArgs e)
{
    textBox1.Text = "X-" + e.X + "Y- " + e.Y;
    _xButton = e.X;
    _yButton = e.Y;
    _placeButton = true;
}

最后

 private void AddLogo_Click_1(object sender, EventArgs e)
{
   if(_placeButton)
    {
      _placeButton = false;
      var button1 = new Button { Location = new Point(_xButton, _yButton) };
   
      Controls.Add(button1);
   }  
    
}
