Exemples

The following code sample creates a ConnectionEnumerator 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 ConnMgr_GetEnum_Current
{
    class Program
    {
        static void Main(string[] args)
        {
            // The package is one of the SSIS Samples.
            string mySample = @"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx";

            // Create an application and load the sample.
            Application app = new Application();
            Package pkg = app.LoadPackage(mySample, null);

            // Get the Connections collection from the package.
            Connections conns = pkg.Connections;
            
            //Create the enumerator.
            ConnectionEnumerator myEnumerator = conns.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);
        }
    }
}

Namespace ConnMgr_GetEnum_Current
    Class Program
        Shared  Sub Main(ByVal args() As String)
            ' The package is one of the SSIS Samples.
            Dim mySample As String =  "C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx" 
 
            ' Create an application and load the sample.
            Dim app As Application =  New Application() 
            Dim pkg As Package =  app.LoadPackage(mySample,Nothing) 
 
            ' Get the Connections collection from the package.
            Dim conns As Connections =  pkg.Connections 
 
            'Create the enumerator.
            Dim myEnumerator As ConnectionEnumerator =  conns.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

Sample Output:

The collection contains the following values:

[0] localhost.AdventureWorks
