C# 使用Windows API获取系统当前鼠标信息(图案)

  通过使用Windows API来获取当前鼠标的图案,不论是系统图片还是自定义图标都能够获取到,在这个示例中,为了方便测试,给Form1添加了一个KeyPress事件,在程序激活状态下,将鼠标移动到任意能使鼠标图案不同的地方,随便按下一个按键,将会将当前鼠标图案描绘到Form1窗体中。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace GetWindowsCurrentCursorByWindowsAPI
{
    public partial class Form1 : Form
    {
        [StructLayout(LayoutKind.Sequential)]
        struct CURSORINFO
        {
            public int cbSize;
            public int flags;
            public IntPtr hCursor;
            public Point ptScreenPos;
        }
        [DllImport("user32.dll")]
        static extern bool GetCursorInfo(out CURSORINFO pci);
        private const int CURSOR_SHOWING = 0x00000001;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_KeyPress(object sender, KeyPressEventArgs e)
        {
            CURSORINFO vCurosrInfo;
            vCurosrInfo.cbSize = Marshal.SizeOf(typeof(CURSORINFO));
            GetCursorInfo(out vCurosrInfo);
            if ((vCurosrInfo.flags & CURSOR_SHOWING) != CURSOR_SHOWING) return;
            Cursor vCursor = new Cursor(vCurosrInfo.hCursor);
            Graphics vGraphics = Graphics.FromHwnd(Handle);
            Rectangle vRectangle = new Rectangle(95, 50, 32, 32);
            vGraphics.FillRectangle(new SolidBrush(BackColor), vRectangle);
            vCursor.Draw(vGraphics, vRectangle);
        }
    }
}
