如何通过.NET API打开AutoCAD 2015

Question

我已经浏览了一个小时,还没有找到有助于此的东西.我正在使用C#从VS2013中的.NET API打开AutoCAD,但出于某种原因,我无法让AutoCAD实际启动.我正在使用以下代码:

using System;
using System.Runtime.InteropServices;

using Autodesk.AutoCAD.Interop;
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.ApplicationServices;

namespace IOAutoCADHandler
{
    public static class ACADDocumentManagement
    {
        [CommandMethod("ConnectToAcad")]
        public static void ConnectToAcad()
        {

            AcadApplication acAppComObj = null;
            // no version number so it will run with any version
            const string strProgId = "AutoCAD.Application";

            // Get a running instance of AutoCAD
            try
            {
                acAppComObj = (AcadApplication)Marshal.GetActiveObject(strProgId);
            }
            catch // An error occurs if no instance is running
            {
                try
                {
                    // Create a new instance of AutoCAD
                    acAppComObj = (AcadApplication)Activator.CreateInstance(Type.GetTypeFromProgID(strProgId), true);
                }
                catch   //// STOPS HERE
                {
                    // If an instance of AutoCAD is not created then message and exit
                    // NOTE: always shows this box and never opens AutoCAD
                    System.Windows.Forms.MessageBox.Show("Instance of 'AutoCAD.Application'" +
                                                         " could not be created.");

                    return;
                }
            }

            // Display the application and return the name and version
            acAppComObj.Visible = true;
            System.Windows.Forms.MessageBox.Show("Now running " + acAppComObj.Name +
                                                 " version " + acAppComObj.Version);

            // Get the active document
            AcadDocument acDocComObj;
            acDocComObj = acAppComObj.ActiveDocument;

            // Optionally, load your assembly and start your command or if your assembly
            // is demandloaded, simply start the command of your in-process assembly.
            acDocComObj.SendCommand("(command " + (char)34 + "NETLOAD" + (char)34 + " " +
                                    (char)34 + @"C:\Users\Administrator\Documents\All Code\main-libraries\IOAutoCADHandler\bin\Debug\IOAutoCADHandler.dll" + (char)34 + ") ");

            acDocComObj.SendCommand("DRAWCOMPONENT");
        }
    }

不幸的是,它始终在嵌套catch语句处停止,并始终显示弹出框而不打开AutoCAD.关于如何至少为我打开AutoCAD的任何建议？
