本文针对WinForm ToolTip使用方法进行实例总结，希望对大家学习C#程序设计有所帮助。具体如下：

程序功能代码如下：

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>    /// 为控件提供Tooltip    /// </summary>    /// <param name="control">控件</param>    /// <param name="tip">ToolTip</param>    /// <param name="message">提示消息</param>    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;    }    /// <summary>    /// 为控件提供Tooltip    /// </summary>    /// <param name="control">控件</param>    /// <param name="tip">ToolTip</param>    /// <param name="message">提示消息</param>    /// <param name="durationTime">保持提示的持续时间</param>    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;    }    /// <summary>    /// 为控件提供Tooltip    /// </summary>    /// <param name="control">控件</param>    /// <param name="tip">ToolTip</param>    /// <param name="message">提示消息</param>    /// <param name="xoffset">水平偏移量</param>    /// <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;    }    /// <summary>    /// 为控件提供Tooltip    /// </summary>    /// <param name="control">控件</param>    /// <param name="tip">ToolTip</param>    /// <param name="message">提示消息</param>    /// <param name="xoffset">水平偏移量</param>    /// <param name="yoffset">垂直偏移量</param>    /// <param name="durationTime">保持提示的持续时间</param>    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;    }  }}

使用方法示例：

using System;using System.Windows.Forms;using WinFormUtilHelpV2;namespace TooltipToolV2Test{  public partial class Form1 : Form  {    public Form1()    {      InitializeComponent();    }    private void button1_Click(object sender, EventArgs e)    {      button1.ShowTooltip(toolTip, "button1_Click");    }    private void listBox1_Click(object sender, EventArgs e)    {      listBox1.ShowTooltip(toolTip, "listBox1_Click", 500);    }  }}

代码运行效果如下：
