解决C# winForm自定义鼠标样式的两种实现方法详解

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));

}
