Параметры

index
Тип: System. . :: . .Object
The name, description, ID, or index of the object to return from the collection.

Значение свойства

Тип: Microsoft.SqlServer.Dts.Runtime. . :: . .LogProvider
A LogProvider object.

Замечания

If the call to Contains method returns true, you can access the specified element in the collection by using the syntax LogProviders[index]. If the Contains returns false, this property throws an exception. In C#, this property is the indexer for the LogProviders class.

Примеры

The following code example retrieves an item from the collection by using two methods. The first method uses the logProvs[0] syntax to retrieve the entire object located in the first position of the collection and place it in the logProv object. You can now retrieve all properties from the logProv object as usual. The second method demonstrates how to retrieve a specific property from the first object in the collection.

            Console.WriteLine("The Name of the first connection info is: {0}", nameOfFirstItem)
        End Sub

Sample Output:

The ID of the first connection info is: {1E107E39-DB79-4F02-B8A7-61D88F2DEF63}

The Name of the first connection info is: SSIS log provider for Text files
