Где взять стандартные иконки команд

[avc]

Вот так работает:

Код - C# [Выбрать]

1.    
2.     internal static bool DarkTheme
3.     {
4.       get => AcadApp.Version.Major >= 20 && (short)AcadApp.GetSystemVariable("COLORTHEME") == 0;
5.     }
6.  
7.     internal static Bitmap BuiltinBitmap(string Name)
8.     {
9.       string lib = AcadApp.Version.Major < 20 || DarkTheme ? "acadbtn.xmx" : "acadbtn_light.xmx";
10.       string filename = System.Windows.Forms.Application.ExecutablePath.Replace("acad.exe", lib);
11.       return ResourceManager.GetBitmap(filename, Name, ResourceManager.RC_RCDATA);
12.     }
13.  
14. [CommandMethod("IconTest")]
15.     public static void IconTestCommand()
16.     {
17.       Document doc = AcadApp.DocumentManager.MdiActiveDocument;
18.       Editor ed = doc.Editor;
19.       PromptStringOptions pso = new PromptStringOptions("Image name? "){
20.        AllowSpaces = false, DefaultValue = "RCDATA_16_ABOUT" };
21.       PromptResult pr = ed.GetString(pso);
22.       if (pr.Status != PromptStatus.OK) return;
23.       Bitmap bmp = BuiltinBitmap(pr.StringResult);
24.       if (bmp == null)
25.       {
26.         ed.WriteMessage("\nBitmap not loaded\n");
27.         return;
28.       }
29.       using Form f = new Form() {
30.         Name = "Test",
31.         Text = "Test",
32.         MinimumSize = new Size(32, 32),
33.         FormBorderStyle = FormBorderStyle.SizableToolWindow };
34.       PictureBox box = new PictureBox() {
35.         Name = "box",
36.         Dock = DockStyle.Fill,  
37.         SizeMode = PictureBoxSizeMode.CenterImage,
38.         Image = bmp  };
39.       f.Controls.Add(box);
40.       f.ShowDialog();
41.     }

avc,
Оказывается можно еще проще:

Код - C# [Выбрать]

1. System.Drawing.Icon ico = Autodesk.AutoCAD.Internal.Utils.GetAcadResourceIcon("имя ресурса");

Для проверки:

Код - C# [Выбрать]

1. public void GetIconWithId() // This method can have any name
2. {
3.   Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
4.   Editor ed = doc.Editor;
5.   System.Drawing.Icon ico = Autodesk.AutoCAD.Internal.Utils.GetAcadResourceIcon("RCDATA_32_BLOCK");
6.   ed.WriteMessage("Icon size = {0}", ico.Size);
7.   using (System.Windows.Forms.Form f = new System.Windows.Forms.Form()
8.   {
9.     Name = "Test", Text = "Test",
10.     MinimumSize = new System.Drawing.Size(32, 32),
11.     FormBorderStyle = System.Windows.Forms.FormBorderStyle.SizableToolWindow
12.   })
13.   {
14.     System.Windows.Forms.PictureBox box = new System.Windows.Forms.PictureBox()
15.     {
16.       Name = "box",
17.       Dock = System.Windows.Forms.DockStyle.Fill,
18.       SizeMode = System.Windows.Forms.PictureBoxSizeMode.StretchImage,
19.       Image = ico.ToBitmap()
20.     };
21.     f.Controls.Add(box);
22.     f.ShowDialog();
23.   }
24. }
