{
static void Main(string[] args)
{
Application dtsApplication = new Application();
ConnectionInfos connectionInfos = dtsApplication.ConnectionInfos;
// Search for the File connection in the collection
if (connectionInfos.Contains("DTS Connection Manager for Files"))
Console.WriteLine("The collection contains the FILE connection");
else
Console.WriteLine("The collection does not contain the FILE connection");
Console.WriteLine();
}
}

Imports Microsoft.SqlServer.Dts.Runtime
Namespace ConnInfosTest
Class Program
Shared Sub Main(ByVal args() As String)
Dim dtsApplication As Application = New Application()
Dim connectionInfos As ConnectionInfos = dtsApplication.ConnectionInfos
' Search for the File connection in the collection
