c#自定义鼠标形状

更改鼠标指针，需要使用到 Windows API:

1. 添加命名空间的引用：

using System.Runtime.InteropServices; 
using System.Reflection;

2. 声明 API 函数

[DllImport("user32.dll")] 
static extern IntPtr LoadCursorFromFile( string fileName );

3. 在Form_Load 事件中，加载自定义光标

private void Form1_Load(object sender, EventArgs e)
  {
      Cursor customCursor = new Cursor(Cursor.Current.Handle);
      IntPtr customCursorHandle = LoadCursorFromFile("你的自定义鼠标指针的路径");
      customCursor.GetType().InvokeMember("handle", BindingFlags.Public |
      BindingFlags.NonPublic | BindingFlags.Instance |
      BindingFlags.SetField, null, customCursor,
     new object[] { customCursorHandle });
     this.Cursor = customCursor;
  }
