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：
