Modifying AutoCAD support Path through .NETBy Virupaksha Aithal
You can use AutoCAD ActiveX API to manipulate the AutoCAD support path. Refer below code. As usual below code uses late binding technique while accessing ActiveX API.

[CommandMethod("AddSupportPath")]

static public void AddSupportPath()

{

    object acadObject = Application.AcadApplication;

    object preferences =

            acadObject.GetType().InvokeMember("Preferences",

            BindingFlags.GetProperty,

            null, acadObject, null);

    //get the files

    object files =

            preferences.GetType().InvokeMember("Files",

            BindingFlags.GetProperty,

            null, preferences, null);

    //get the support path SupportPath

    string supportPath =

            (string)files.GetType().InvokeMember("SupportPath",

            BindingFlags.GetProperty,

            null, files, null);

    Document doc = Application.DocumentManager.MdiActiveDocument;

    Editor ed = doc.Editor;

    if (!supportPath.Contains("C:\\BatchPublish"))

    {

        supportPath = supportPath + ";" + "C:\\BatchPublish";

        object[] dataArry = new object[1];

        dataArry[0] = supportPath;

        files.GetType().InvokeMember("SupportPath",

                         BindingFlags.SetProperty,

                         null, files, dataArry);

        ed.WriteMessage(supportPath + "\n");

    }

    else

    {

        ed.WriteMessage("Support path already present\n");

    }

}

这里面用到了InvokeMember GetProperty SetProperty, 是不是 Arx 定义的GetPropertyvalue Setpropertyvalue是用的就是这个?

这两个函数需要的特性名称是大小写敏感的，和C或Net规则一致
