以下是一个简单的示例代码，用于将多个CUR格式的光标图像合并为ANI格式的动画：

using System;
using System.Collections.Generic;
using System.Drawing;
using System.Runtime.InteropServices;

class Program
{
    static void Main(string[] args)
    {
        // Load the cursor images
        List<Cursor> cursorList = new List<Cursor>();
        cursorList.Add(new Cursor("image1.cur"));
        cursorList.Add(new Cursor("image2.cur"));
        cursorList.Add(new Cursor("image3.cur"));

        // Create a new ANI animation
        IntPtr aniHandle = CreateAniAnimation(cursorList);

        // Save the ANI animation to a file
        using (var fs = new System.IO.FileStream("animation.ani", System.IO.FileMode.Create))
        {
            byte[] aniBytes = GetAniBytes(aniHandle);
            fs.Write(aniBytes, 0, aniBytes.Length);
        }

        // Clean up resources
        DestroyCursorAni(aniHandle);
        foreach (Cursor cursor in cursorList)
        {
            cursor.Dispose();
        }
    }

    static IntPtr CreateAniAnimation(List<Cursor> cursorList)
    {
        IntPtr[] cursorHandles = new IntPtr[cursorList.Count];
        for (int i = 0; i < cursorList.Count; i++)
        {
            cursorHandles[i] = cursorList[i].Handle;
        }

        IntPtr aniHandle = IntPtr.Zero;
        int result = Animate_CreateCursorIndirect(ref cursorHandles[0], cursorHandles.Length, 100 /* delay in milliseconds */, out aniHandle);
        if (result == 0)
        {
            throw new Exception("Failed to create ANI animation.");
        }

        return aniHandle;
    }

    static byte[] GetAniBytes(IntPtr aniHandle)
    {
        uint aniSize = Animate_GetSize(aniHandle);
        IntPtr aniData = Marshal.AllocHGlobal((int)aniSize);
        Animate_GetData(aniHandle, aniData);
        byte[] aniBytes = new byte[aniSize];
        Marshal.Copy(aniData, aniBytes, 0, (int)aniSize);
        Marshal.FreeHGlobal(aniData);
        return aniBytes;
    }

    [DllImport("user32.dll", SetLastError = true)]
    static extern int Animate_CreateCursorIndirect(ref IntPtr phCursor, int cFrames, int cSteps, out IntPtr phAni);

    [DllImport("user32.dll", SetLastError = true)]
    static extern uint Animate_GetSize(IntPtr hAni);

    [DllImport("user32.dll", SetLastError = true)]
    static extern void Animate_GetData(IntPtr hAni, IntPtr lpBuffer);

    [DllImport("user32.dll", SetLastError = true)]
    static extern void DestroyCursorAni(IntPtr hAni);
}

这段代码首先加载了多个CUR格式的光标图像，并使用CreateAniAnimation()方法将它们合并为一个ANI格式的动画。然后，使用GetAniBytes()方法将ANI数据从句柄中提取出来，并将其保存到名为”animation.ani”的文件中。

请注意，这里使用了Windows API函数Animate_CreateCursorIndirect()来创建ANI动画。我们将CUR图像的句柄传递给它，以及延迟时间和其他参数。在获取ANI数据之前，必须使用Animate_GetSize()函数获取ANI动画的大小。在销毁ANI动画之前，使用DestroyCursorAni()函数释放
