Comentários
If a call to the Contains method returns true, you can access the specified element in the collection by using the syntax ConnectionInfos[index]. If the Contains method returns false, this property throws an exception. In C#, this property is the indexer for the ConnectionInfos class.
Exemplos
The following code example retrieves an item from the collection by using two methods. The first method uses the connectionInfos[0] syntax to retrieve the entire object, located in the first position of the collection and then places it in the connInfo object. You can now retrieve all properties from the ConnectionInfo object as usual. The second method retrieves a specific property from the first object in the collection.
