매개 변수
- index
유형: System.Object
The name, identity, ID, or index of the LogProvider object to return.
속성 값
유형: Microsoft.SqlServer.Dts.Runtime.LogProvider
A LogProvider object from the collection.
예외
| 예외 | 조건 |
|---|---|
| DTS_E_ELEMENTNOTFOUND | The element could not be found in the collection. |
주의
If the call to the Contains method returns true, you can access the specified element in the collection by using the syntax SelectedLogProviders[index]. If the Contains method returns false, this property throws an exception. In C#, this property is the indexer for the SelectedLogProviders class.

The following code example adds and removes log providers for the package, in addition to showing the use of the Contains and Item syntax of [0] for the collection.
