.AcadSelectionSet sset;
         AutoCAD.AcadApplication app;
         app = (AcadApplication)
         System.Runtime.InteropServices.Marshal.GetActiveObject("AutoCAD.Application.16");
         short[] f1 = new short[] { 2 };
         object[] f2 = new object[] { "gtmodel" };

         sset=app.ActiveDocument.SelectionSets.Add("MySelect");
         this.Hide();
         //此次如何激活CAD窗口，让程序在cad中选择

         app.ActiveDocument.Utility.Prompt("请选择对象：");
         sset.SelectOnScreen(f1, f2);
         this.Show();

不知老兄是否解决问题了？我的方法比较复杂，就是模拟鼠标在CAD屏幕上点击一下。
using System.Diagnostics;
加上
[DllImport("User32")]
      public extern static void mouse_event(int dwFlags, int dx, int dy, int dwData, IntPtr dwExtraInfo);
      [DllImport("User32")]
      public extern static void SetCursorPos(int x, int y);
      [DllImport("User32")]
      public extern static bool GetCursorPos(out POINT p);
      [DllImport("User32")]
      public extern static int ShowCursor(bool bShow);
      public struct POINT
      {
         public int X;
         public int Y;
      }
      [Flags]
      public enum MouseEventFlags
      {
         Move = 0x0001,
         LeftDown = 0x0002,
         LeftUp = 0x0004,
         RightDown = 0x0008,
         RightUp = 0x0010,
         MiddleDown = 0x0020,
         MiddleUp = 0x0040,
         Wheel = 0x0800,
         Absolute = 0x8000
      }
//==========================================模拟鼠标左键点击
      private void AutoMouseLeftClick(int x,int y)
      {
         int dx = 0;
         int dy = 0;
         mouse_event((int)(MouseEventFlags.LeftDown | MouseEventFlags.Absolute), dx, dy, 0, IntPtr.Zero);
         mouse_event((int)(MouseEventFlags.LeftUp | MouseEventFlags.Absolute), dx, dy, 0, IntPtr.Zero);


      }
