本文介绍了两种在 WinForm 应用中实现 Tooltip 的方法。第一种方法通过自定义工具类来灵活设置 Tooltip 的显示位置及持续时间；第二种方法则是直接在控件上设置 Tooltip 文本，适用于简单需求。

第一种

using System.Drawing;
using System.Windows.Forms;
 
namespace WinFormUtilHelpV2
{
  /// <summary>
  /// 基于.NET 2.0的Tooltip工具类
  /// </summary>
  public static class TooltipToolV2
  {
    /// <summary>

    public static void ShowTooltip(this Control control, ToolTip tip, string message)
    {
      Point _mousePoint = Control.MousePosition;
      int _x = control.PointToClient(_mousePoint).X;
      int _y = control.PointToClient(_mousePoint).Y;
      tip.Show(message, control, _x, _y);
      tip.Active = true;
    }

    public static void ShowTooltip(this Control control, ToolTip tip, string message, int durationTime)
    {
      Point _mousePoint = Control.MousePosition;
      int _x = control.PointToClient(_mousePoint).X;
      int _y = control.PointToClient(_mousePoint).Y;
      tip.Show(message, control, _x, _y, durationTime);
      tip.Active = true;
    }

    /// <param name="yoffset">垂直偏移量</param>
    public static void ShowTooltip(this Control control, ToolTip tip, string message, int xoffset, int yoffset)
    {
      Point _mousePoint = Control.MousePosition;
      int _x = control.PointToClient(_mousePoint).X;
      int _y = control.PointToClient(_mousePoint).Y;
      tip.Show(message, control, _x + xoffset, _y + yoffset);
      tip.Active = true;
    }

    public static void ShowTooltip(this Control control, ToolTip tip, string message, int xoffset, int yoffset, int durationTime)
    {
      Point _mousePoint = Control.MousePosition;
      int _x = control.PointToClient(_mousePoint).X;
      int _y = control.PointToClient(_mousePoint).Y;
      tip.Show(message, control, _x + xoffset, _y + yoffset, durationTime);
      tip.Active = true;
    }
  }
}
 
 
第二种
 
private void SetRadioButtonToolTip() 
{ 
    // Create the ToolTip and associate with the Form container. 
    ToolTip toolTip1 = new ToolTip();

    // Set up the delays for the ToolTip. 
    toolTip1.AutoPopDelay = 5000; 
    toolTip1.InitialDelay = 1000; 
    toolTip1.ReshowDelay = 500; 
    // Force the ToolTip text to be displayed whether or not the form is active. 
    toolTip1.ShowAlways = true;

    // Set up the ToolTip text for the Button and Checkbox. 
    toolTip1.SetToolTip(this.radioButton4, "光标"); 
    toolTip1.SetToolTip(this.radioButton1, "标签"); 
    toolTip1.SetToolTip(this.radioButton2, "面板"); 
    toolTip1.SetToolTip(this.radioButton3, "按钮"); 
}
