本文实例讲述了C#实现获取鼠标句柄的方法，分享给大家供大家参考。具体实现方法如下：
一、调用user32.dll
(1)引用
using System.Runtime.InteropServices;
(2)调用方法
1、获取窗口标题
[DllImport( "user32.dll" )] public static extern int GetWindowText( IntPtr hWnd, StringBuilder lpString,int nMaxCount );
注：hWnd 窗口句柄 lpString 窗口标题 nMaxCount 最大值
2、获取类名
[DllImport( "user32.dll" )] public static extern int GetClassName( IntPtr hWnd, StringBuilder lpString,int nMaxCount );
注：hWnd 句柄 lpString 类名 nMaxCount 最大值
3、根据坐标获取窗口句柄
[DllImport( "user32.dll" )] public static extern IntPtr WindowFromPoint(Point point);
注：point 坐标
二、显示数据
(1) 获取鼠标坐标
int x = Cursor.Position.X;
int y = Cursor.Position.Y;
this.textBox4.Text = string.Format( "({0},{1})" , x, y);
(2) 获取句柄
Point p = new Point(x,y); IntPtr formHandle = WindowFromPoint(p); this.textBox1.Text = formHandle.ToString();
(3) 得到窗口标题
GetWindowText(formHandle,title,title.Capacity); this.textBox2.Text = title.ToString();
(4)得到窗体的类名
StringBuilder cllassName = new StringBuilder(); GetClassName(formHandle,cllassName,cllassName.Capacity); this.textBox3.Text = cllassName.ToString();
(5)Load事件
this.timer1.Enabled = !this.timer1.Enabled;
注：动态显示信息
三、运行结果如下图所示：
