New to .NET - Loading and Running an Application

DGCSCAD — Mon, 27 Nov 2023 12:29:02 GMT

I'm just starting out with .NET and am trying to get this code (from Norman Yuan) to run:

using System.Collections.Generic; using System.Linq; using Autodesk.AutoCAD.DatabaseServices; using Autodesk.AutoCAD.Runtime; using ConsoleApp1; using CadApp = Autodesk.AutoCAD.ApplicationServices.Application; [assembly: CommandClass(typeof(MyCommands))] namespace ConsoleApp1 { public class MyCommands { [CommandMethod("ListDataLinks")] public static void GetDataLinks() { var dwg = CadApp.DocumentManager.MdiActiveDocument; var ed = dwg.Editor; try { var links = GetDataLinksInDb(dwg.Database); if (links.Count() > 0) { ed.WriteMessage("\nExcel Data Link(s) found in current drawing:"); foreach (var link in links) { ed.WriteMessage($"\n\t{link}"); } ed.WriteMessage("\n"); } else { ed.WriteMessage("\nNo Excel Data Link found in current drawing.\n"); } } catch (System.Exception ex) { ed.WriteMessage("\nError:\n{0}.", ex.Message); } finally { Autodesk.AutoCAD.Internal.Utils.PostCommandPrompt(); } } [CommandMethod("UpdateDataLink")] public static void RepathDataLink() { var dwg = CadApp.DocumentManager.MdiActiveDocument; var ed = dwg.Editor; string linkName = "JEI - Cable"; string newSource = @"C:\PRD\Apps\LISP\Datalink Test\Data Link Test 002.xlsx"; using (var tran = dwg.TransactionManager.StartTransaction()) { var link = GetDataLink(linkName, dwg.Database, tran); if (link != null) { var source = link.ConnectionString; CadApp.ShowAlertDialog($"Data Link: \"{linkName}\"" + $"\nCurrent Link Source: \"{source}\""); var suffix = ""; var pos = source.IndexOf("!"); if (pos > 0) { suffix = source.Substring(pos + 1); } if (!string.IsNullOrEmpty(suffix)) { newSource = newSource + "!" + suffix; } if (!link.IsWriteEnabled) link.UpgradeOpen(); link.ConnectionString = newSource; link.Update(UpdateDirection.SourceToData, UpdateOption.AllowSourceUpdate); } tran.Commit(); } } private static IEnumerable<string> GetDataLinksInDb(Database db) { var links = new List<string>(); using (var tran = db.TransactionManager.StartTransaction()) { var dic = (DBDictionary)tran.GetObject(db.DataLinkDictionaryId, Autodesk.AutoCAD.DatabaseServices.OpenMode.ForRead); foreach (DBDictionaryEntry entry in dic) { links.Add(entry.Key); } tran.Commit(); } return links; } private static DataLink GetDataLink(string linkName, Database db, Autodesk.AutoCAD.DatabaseServices.Transaction tran) { DataLink link = null; var dic = (DBDictionary)tran.GetObject(db.DataLinkDictionaryId, Autodesk.AutoCAD.DatabaseServices.OpenMode.ForRead); foreach (DBDictionaryEntry entry in dic) { if (entry.Key.ToUpper() == linkName.ToUpper()) { link = (DataLink)tran.GetObject(entry.Value, Autodesk.AutoCAD.DatabaseServices.OpenMode.ForRead); break; } } return link; } } }

It builds with no errors and I think it's loading when I NETLOAD it, but I get an "Unkown Command" when I run a command (UpdateDataLink) from the code.

Not sure of what I'm missing...?

Hi,

namespace ConsoleApp1

Sounds strange...

You have to understand the basics of .NET and how to to build a plugin (a dll netloaded from AutoCAD).

To build an AutoCAD plugin project, you can start from here.
