直接贴上代码，不懂的可以问我

using Autodesk.AutoCAD.EditorInput;
using Autodesk.AutoCAD.GraphicsInterface;
using Copper.AutocadApi.Properties;
using System.Drawing;
namespace Copper.AutocadApi.ExtendedMethod;
public static class Utils
{
private static ImageBGRA32 _FormatBrushImage = null;
public static void CreateFormatBrushCursor()
{
if (_FormatBrushImage==null)
{
using var bmp =Resources.FormatBrush;//把透明背景的图片放到资源里面直接调用
for (var i = 0; i < bmp.Width; i++)
{
for (var j = 0; j < bmp.Height; j++)
{
var pixel = bmp.GetPixel(i, j);
if ((pixel.A == 0 && pixel.R == 0 && pixel.G == 0 && pixel.B == 0)|| pixel.A == 0 && pixel.R == 255 && pixel.G == 255 && pixel.B == 255)
{
bmp.SetPixel(i, j, Color.Magenta);
}
}
}
_FormatBrushImage = Autodesk.AutoCAD.Internal.Utils.ConvertBitmapToAcGiImageBGRA32(bmp);
}
new CursorBadgeUtilities().AddSupplementalCursorImage(_FormatBrushImage, 1);
}
public static void DeleteFormatBrushCursor()
{
var cbu = new CursorBadgeUtilities();
if (cbu.HasSupplementalCursorImage() && _FormatBrushImage!=null)
{
cbu.RemoveSupplementalCursorImage(_FormatBrushImage);
}
}
}

using Autodesk.<a href="http://bbs.mjtd.com/forum-41-1.html" target="_blank" class="relatedlink">AutoCAD</a>.EditorInput; 
using Autodesk.AutoCAD.GraphicsInterface; 
using Copper.AutocadApi.Properties; 
using System.Drawing; 
 
namespace Copper.AutocadApi.ExtendedMethod; 
 
public static class Utils 
{ 
    private static ImageBGRA32 _FormatBrushImage = null; 
    public static void CreateFormatBrushCursor() 
    { 
        if (_FormatBrushImage==null) 
        { 
            using var bmp =Resources.FormatBrush;//把透明背景的图片放到资源里面直接调用 
            for (var i = 0; i < bmp.Width; i++) 
            { 
                for (var j = 0; j < bmp.Height; j++) 
                { 
                    var pixel = bmp.GetPixel(i, j); 
                    if ((pixel.A == 0 && pixel.R == 0 && pixel.G == 0 && pixel.B == 0)|| pixel.A == 0 && pixel.R == 255 && pixel.G == 255 && pixel.B == 255) 
                    { 
                        bmp.SetPixel(i, j, Color.Magenta); 
                    } 
                } 
            } 
            _FormatBrushImage = Autodesk.AutoCAD.Internal.Utils.ConvertBitmapToAcGiImageBGRA32(bmp); 
        } 
        new CursorBadgeUtilities().AddSupplementalCursorImage(_FormatBrushImage, 1); 
    } 
 
    public static void DeleteFormatBrushCursor() 
    { 
        var cbu = new CursorBadgeUtilities(); 
 
        if (cbu.HasSupplementalCursorImage() && _FormatBrushImage!=null) 
        { 
            cbu.RemoveSupplementalCursorImage(_FormatBrushImage); 
        } 
    } 
}

这里有个关键点，要注意图的背景色更改为Color.Magenta，如下

bmp.SetPixel(i, j, Color.Magenta);

复制代码

调用时把方法放在你需要更改鼠标样式的位置，如下

[CopperCmd("0DF476F9-87DF-46B8-917A-FD3A49F5CF9F", CommandFlags.Redraw)]
public class CopyPropertiesCmd : AutocadCommand
{
protected override void Execute()
{
......
if (!this.TryCreateFilterForSelectBlockByName(new List<string> { bref.GetBlockName() }, out var filter)) return;
var sourseFilter = new SelectionFilter(filter);
var sourseOption = new PromptSelectionOptions
{
......
};
Utils.CreateFormatBrushCursor();//此处设置图标
var objSel = Ed.GetSelection(sourseOption, sourseFilter);
Utils.DeleteFormatBrushCursor();//此处取消
if (objSel.Status != PromptStatus.OK) return;
var targetIds = objSel.Value.GetObjectIds();
foreach (var id in targetIds)
{
... ...
}
}
}

复制代码

本做法参考了keanw的博客地址如下：
