Something like this would work, it uses AutoCAD.Interop:
{code}
[CommandMethod("TLOD", CommandFlags.Modal)]
public void TLOD()
{
/*
;;
;; contents of "C:/_TLOAD.lsp"
;;
(defun c:LISPCOM1 ()
(prompt "\nLoaded: C:/_TLOAD.lsp")
(prompt "\nLISPCOM1 Executed!")
(prompt "\nNice")
(princ)
)
*/

AcadDocument curAcadDoc = (AcadDocument)AcApp.DocumentManager.MdiActiveDocument.AcadDocument;
string lispPath = "C:/_TLOAD.lsp";
string loadStr = String.Format("(load \"{0}\") "/*space after closing paren!!!*/, lispPath);
curAcadDoc.SendCommand(loadStr);
curAcadDoc.SendCommand("LISPCOM1 "/*space after command name!!!*/);
}
{code}

It won't load it application wide. You would have to run 'TLOD' again for each document that you open.
And you can use 'HostApplicationServices.FindFile()' to find a file that might be in AutoCAD's path, if needed.

No problem! I thought I woudl follow it up with, if you do want a lisp file to be loaded in all dwgs and subsequent opened dwgs:
{code}
AcadDocument curAcadDoc = (AcadDocument)AcApp.DocumentManager.MdiActiveDocument.AcadDocument;
curAcadDoc.SendCommand("(vl-load-com) "/*space after closing paren!!!*/);
string lispPath = "C:/_TLOAD.lsp";
string loadStr = String.Format("(vl-load-all \"{0}\") "/*space after closing paren!!!*/, lispPath);
curAcadDoc.SendCommand(loadStr);
{code}

Hi,

I know this topic is quite old, but while using the you provided I am getting this error.

expected class delegate enum interface or struct (at void)

I have modified the code to suit my needs please help me resolve it.

code

using Microsoft.Win32;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.Runtime;
using acApp = Autodesk.AutoCAD.ApplicationServices.Application;

[CommandMethod("TLOD", CommandFlags.Modal)]

public void TLOD()
{
AcadDocument curAcadDoc = (AcadDocument)AcApp.DocumentManager.MdiActiveDocument.AcadDocument;
curAcadDoc.SendCommand("(vl-load-com) "/*space after closing paren!!!*/);
string lispPath = (string)Registry.LocalMachine.GetValue(@"SOFTWARE\XXXX\YYYY", "InstallDir", null);
string loadStr = String.Format("(vl-load-all \"{0}\") "/*space after closing paren!!!*/, lispPath);
curAcadDoc.SendCommand(loadStr);
}

Any help would be appreciated.

I believe I have to declare the namespace and also public class but I do not know how. Any example Please..

AcadDocument curAcadDoc = (AcadDocument)Autodesk.AutoCAD.ApplicationServices.Application .DocumentManager.MdiActiveDocument.GetAcadDocument();
            curAcadDoc.SendCommand("(vl-load-com) "/*space after closing paren!!!*/);
            string lispPath = "C:LU.lsp";
            string loadStr = String.Format("(vl-load-all \"{0}\") "/*space after closing paren!!!*/, lispPath);
            curAcadDoc.SendCommand(loadStr)

try with this
