使用例
次のコード例では、LogProviders クラスを使用して、GetEnumerator の使用方法を示しています。 LogProviders コレクションは DTSReadOnlyCollectionBase から継承され、GetEnumerator をオーバーライドして、そのコレクションの適切な列挙子を提供します。

using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
namespace LogProviderInfos_testing
{
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);
}
}
}
