1、使用 Cursor属性设置鼠标形状
<Button Cursor="Hand" />
鼠标形状的枚举数值如下所示：
public enum CursorType
{
None = 0,
No = 1,
Arrow = 2,
AppStarting = 3,
Cross = 4,
Help = 5,
IBeam = 6,
SizeAll = 7,
SizeNESW = 8,
SizeNS = 9,
SizeNWSE = 10,
SizeWE = 11,
UpArrow = 12,
Wait = 13,
Hand = 14,
Pen = 15,
ScrollNS = 16,
ScrollWE = 17,
ScrollAll = 18,
ScrollN = 19,
ScrollS = 20,
ScrollW = 21,
ScrollE = 22,
ScrollNW = 23,
ScrollNE = 24,
ScrollSW = 25,
ScrollSE = 26,
ArrowCD = 27
}
2、加载外部图片作为鼠标形状
public class CursorSafeHandle : SafeHandle
{
public CursorSafeHandle(IntPtr preexistingHandle, bool ownsHandle)
: base(IntPtr.Zero, ownsHandle)
{
handle = preexistingHandle;
}
public override bool IsInvalid
{
get { return handle == IntPtr.Zero; }
}
protected override bool ReleaseHandle()
{
return true;
}
}
Bitmap dimage = new Bitmap("update.png");
var handle = dimage.GetHicon();
var c = new CursorSafeHandle(handle, true);
var cursor= CursorInteropHelper.Create(c);
testButton.Cursor = cursor;
3、创建Bitmap图像
我们还可以在GDI+上绘制图形作为鼠标形状：
private Bitmap FillGraphToBitmap()
{
var backBitmap = new Bitmap(20, 20);
using (Graphics graphics = Graphics.FromImage(backBitmap))
{
// 设置背景色
graphics.Clear(System.Drawing.Color.Transparent);
// 绘制圆
Brush greenBrush = new SolidBrush(Color.Green);
graphics.FillEllipse(greenBrush, 0, 0, backBitmap.Width, backBitmap.Height);
graphics.Dispose();
}
return backBitmap;
}
