public Configuration this [
    Object index

Параметры

index
The name, description, ID, or index of the Configuration object to return.

Значение свойства

A Configuration object.

Замечания

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

Пример

The following code example uses the Contains method to see if item syntax is available. If true, the code example uses the item syntax of p.Configurations[0].Name to get the name of the configuration located in the first position of the collection, index position 0.
