Esempio
Nell'esempio di codice seguente viene usata la classe per illustrare l'uso LogProviders di GetEnumerator. La LogProviders raccolta eredita da DTSReadOnlyCollectionBasee esegue l'override GetEnumerator di per fornire un enumeratore appropriato per la raccolta.

class Program
{
static void Main(string[] args)

// The package is one of the SSIS Samples. The package
// was modified in the designer to log to the SSIS log
// provider for Text files before being loaded
// for this code example.
string mySample = @"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx";
// Create the Application, and load the sample.
Application app = new Application();
Package pkg = app.LoadPackage(mySample, null);
// Get the LogProviders collection from the package.
LogProviders logProvs = pkg.LogProviders;
//Create the Enumerator.
LogProviderEnumerator myEnumerator = logProvs.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);
