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：
