How to: Iterate Through All Properties of an Object in Visual Basic .NET

SQL Server 2005

This section describes how to iterate through all the properties that belong to an object.

The code example iterates through the Properties collection of the StoredProcedure object and displays them on the Visual Studio Output screen.

  1. Start Visual Studio 2005.

  2. From the File menu, select New Project. The New Project dialog box appears.

  3. In the Project Types pane, select Visual Basic. In the Templates pane, select Console Application.

  4. (Optional) In the Name box, type the name of the new application.

  5. Click OK to load the Visual Basic console application template.

  6. On the Project menu, select Add Reference item. The Add Reference dialog box appears. Select Browse and locate the SMO assemblies in the C:\Program Files\Microsoft SQL Server\90\SDK\Assemblies folder. Select the following files:

    Microsoft.SqlServer.ConnectionInfo.dll

    Microsoft.SqlServer.Smo.dll

    Microsoft.SqlServer.SqlEnum.dll

    Microsoft.SqlServer.SmoEnum.dll

  7. On the View menu, click Code.-Or-Select the Module1.vb window to display the code window.

  8. In the code, before any declarations, type the following Imports statements to qualify the types in the SMO namespace:

    Imports Microsoft.SqlServer.Management.Smo
    Imports Microsoft.SqlServer.Management.Common
    
  9. Insert the code that follows this procedure into the main program.

  10. Run and build the application.

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Set properties on the uspGetEmployeedManagers stored procedure on the AdventureWorks database.
Dim db As Database
db = srv.Databases("AdventureWorks")
Dim sp As StoredProcedure
sp = db.StoredProcedures("uspGetEmployeeManagers")
sp.AnsiNullsStatus = False
sp.QuotedIdentifierStatus = False
'Iterate through the properties of the stored procedure and display.
'Note the Property object requires [] parentheses to distinguish it from the Visual Basic key word.
Dim p As [Property]
For Each p In sp.Properties
    Console.WriteLine(p.Name & p.Value)
Next

The Property object has been placed in square parentheses because it is also a Visual Basic keyword.
