public has an error message under public static void for the following code

[irahmanJS6UB]

Hello, for the following code I get a red line under public and I am not sure as to why, can someone help me?

[CommandMethod("OpenDrawing", CommandFlags.Session)]
public static void OpenDrawing()
{
string strFileName = "C:\\campus.dwg";
DocumentCollection acDocMgr = Application.DocumentManager;

if (File.Exists(strFileName))
{
acDocMgr.Open(strFileName, false);
}
else
{
acDocMgr.MdiActiveDocument.Editor.WriteMessage("File " + strFileName +
" does not exist.");
}
}

Thank you!

Look in the error message box. You probably didn't declare a namespace and a public class. It feels like you should read the VS tutorial first and compile "Hello world".

using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.Runtime;
using System.IO;

namespace Aspecific.AcadCommands
{
    public static class TestCommand
    {

        [CommandMethod("OpenDrawing", CommandFlags.Session)]
        public static void OpenDrawing()
        {
            string strFileName = "C:\\campus.dwg";
            DocumentCollection acDocMgr = Application.DocumentManager;

            if (File.Exists(strFileName))
            {
                acDocMgr.Open(strFileName, false);
            }
            else
            {
                acDocMgr.MdiActiveDocument.Editor.WriteMessage("File " + strFileName +
                " does not exist.");
            }
        }
    }
}

Perhaps this?

Hi,

I suspect you didn't start your project from a "class library" one.

You can start from this topic to see how to create an AutoCAD .NET project.
