第一种：（调用系统API）
首先引入两个命名空间
using System.Runtime.InteropServices;
using System.Reflection;
导入API
[DllImport("user32.dll")]
public static extern IntPtr LoadCursorFromFile(string fileName);
[DllImport("user32.dll")]
public static extern IntPtr SetCursor(IntPtr cursorHandle);
[DllImport("user32.dll")]
public static extern uint DestroyCursor(IntPtr cursorHandle);
接下来使用自己的鼠标样式
private void Form1_Load(object sender, EventArgs e)
{
Cursor myCursor = new Cursor(Cursor.Current.Handle);
IntPtr colorCursorHandle = LoadCursorFromFile("my.cur");//鼠标图标路径
myCursor.GetType().InvokeMember("handle", BindingFlags.Public |
BindingFlags.NonPublic | BindingFlags.Instance |
BindingFlags.SetField, null, myCursor,
new object[] { colorCursorHandle });
this.Cursor = myCursor;
}
第二种：（不用API方式的，鼠标样式只需要一张背景透明的图片就行了，png或gif格式的）
public void SetCursor(Bitmap cursor, Point hotPoint)
{
int hotX = hotPoint.X;
int hotY = hotPoint.Y;
Bitmap myNewCursor = new Bitmap(cursor.Width * 2 - hotX, cursor.Height * 2 - hotY);
Graphics g = Graphics.FromImage(myNewCursor);
g.Clear(Color.FromArgb(0, 0, 0, 0));
g.DrawImage(cursor, cursor.Width - hotX, cursor.Height - hotY, cursor.Width,
cursor.Height);
this.Cursor = new Cursor(myNewCursor.GetHicon());
g.Dispose();
myNewCursor.Dispose();
}
在你想要改变鼠标样式的事件里头使用这个方法就行了，如：
private void Form1_Load(object sender, EventArgs e)
{
Bitmap a=(Bitmap)Bitmap.FromFile("myCur.png");
SetCursor(a, new Point(0, 0));
}
