c# example for accessing the view table

问题：
Is there a c# (sharp) example that shows how to access views from .NET?

解答：
Here is an example that outputs the names of the views to the command line.

1. // Namespaces in AutoCAD assemblies
   
2. using Autodesk.AutoCAD.Runtime;
   
3. using Autodesk.AutoCAD.ApplicationServices;
   
4. using Autodesk.AutoCAD.DatabaseServices;
   
5. using Autodesk.AutoCAD.EditorInput;
   
6. 
   
7. 
   
8.   [Autodesk.AutoCAD.Runtime.CommandMethod("listViews")]
   
9.   public void listViews()
   
10.   {
    
11.    Database db;
    
12.    Transaction tr;
    
13.    ViewTable vt;
    
14.    ViewTableRecord vtRec;
    
15.    Autodesk.AutoCAD.EditorInput.Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;
    
16. 
    
17. 
    
18.    try
    
19.    {
    
20.     db = HostApplicationServices.WorkingDatabase;
    
21.     using(tr = db.TransactionManager.StartTransaction())
    
22.     {
    
23.      using(vt = (ViewTable)tr.GetObject(db.ViewTableId, OpenMode.ForRead))
    
24.      {
    
25.       foreach(ObjectId id in vt)
    
26.       {
    
27.        vtRec = (ViewTableRecord)tr.GetObject(id, OpenMode.ForRead);
    
28.        ed.WriteMessage("Name of View = " + vtRec.Name + "\n");
    
29.       }
    
30. 
    
31. 
    
32.      }
    
33.      tr.Commit();
    
34.     }
    
35.    }
    
36.    catch(System.Exception ex)
    
37.    {
    
38.     ed.WriteMessage(ex.ToString());
    
39. 
    
40.    }
