我创建了一个示例来演示如何创建自定义控件。

创建一个UserControl并给出名称示例并将以下代码放入.cs文件中。

[DefaultEvent("Click")] 
public partial class Sample : UserControl 
{ 
    private string _text; 
    [Browsable(true)] 
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)] 
    public override string Text 
    { 
     get 
     { 
      return _text; 
     } 
     set 
     { 
      _text = value; 
     } 
    } 
    private bool _mouseDown = false; 
    private bool _mouseHover = false; 
    private bool _invalidateRequired = true; 

    public Sample() 
    { 
     InitializeComponent(); 
    } 
    protected override void OnMouseDown(MouseEventArgs e) 
    { 
     base.OnMouseDown(e); 
     _mouseDown = true; 
     _invalidateRequired = true; 
     this.Invalidate(); 
    } 
    protected override void OnMouseUp(MouseEventArgs e) 
    { 
     base.OnMouseUp(e); 
     _mouseDown = false; 
     _invalidateRequired = true; 
     this.Invalidate(); 
    } 
    protected override void OnMouseMove(MouseEventArgs e) 
    { 
     base.OnMouseMove(e); 
     _mouseHover = true; 
     if (_invalidateRequired) 
     { 
      this.Invalidate(); 
      _invalidateRequired = false; 
     } 
    } 
    protected override void OnMouseLeave(EventArgs e) 
    { 
     base.OnMouseLeave(e); 
     _mouseHover = false; 

     this.Invalidate(); 
     _invalidateRequired = true; 
    } 
    protected override void OnPaint(PaintEventArgs e) 
    { 
     base.OnPaint(e); 
     Rectangle r = new Rectangle(0, 0, this.ClientRectangle.Width - 1, this.ClientRectangle.Height - 1); 
     Color bg = Color.White; 
     Color fr = Color.Gray; 
     Color br = Color.FromArgb(173, 178, 173); 
     if (_mouseDown) 
     { 
      bg = Color.FromArgb(24, 162, 231); 
      fr = Color.White; 
     } 
     if (_mouseHover) 
      br = Color.FromArgb(24, 162, 231); 
     e.Graphics.FillRectangle(new SolidBrush(bg), r); 
     e.Graphics.DrawRectangle(new Pen(br, 3), r); 
     StringFormat sf = new StringFormat(); 
     sf.LineAlignment = StringAlignment.Center; 
     sf.Alignment = StringAlignment.Center; 
     e.Graphics.DrawString(Text, this.Font, new SolidBrush(fr), r, sf);    
    } 
}
