Пример

The following code sample creates a DBProviderInfoEnumerator using the GetEnumerator method, and then iterates over the collection.

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;

namespace DBProvInfos_GetEnum
{
    class Program
    {
        static void Main(string[] args)
        {
            Application app = new Application();
            DBProviderInfos dbprovInfos = app.DBProviderInfos;

            //Create the Enumerator.
            DBProviderInfoEnumerator myEnumerator = dbprovInfos.GetEnumerator();
            Console.WriteLine("The collection contains the following values:");
            int i = 0;
            while ((myEnumerator.MoveNext()) && (myEnumerator.Current != null))
                Console.WriteLine("[{0}] {1}", i++, myEnumerator.Current.Name);
        }
    }
}

Imports System
Imports System.Collections.Generic
Imports System.Text
Imports Microsoft.SqlServer.Dts.Runtime
 
Namespace DBProvInfos_GetEnum
    Class Program
        Shared  Sub Main(ByVal args() As String)
            Dim app As Application =  New Application() 
            Dim dbprovInfos As DBProviderInfos =  app.DBProviderInfos 
 
            'Create the Enumerator.
            Dim myEnumerator As DBProviderInfoEnumerator =  dbprovInfos.GetEnumerator() 
            Console.WriteLine("The collection contains the following values:")
            Dim i As Integer =  0 
            While (myEnumerator.MoveNext()) &&(myEnumerator.Current <> Nothing)
            Console.WriteLine("[{0}] {1}",i = Console.WriteLine("[{0}] {1}",i + 1
            End While
        End Sub
    End Class
End Namespace
