The name, ID, description, or index of the item to locate in the collection.

Valeur de propriété

A PipelineComponentInfo object.

Notes

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

Exemple

The following code example retrieves an item from the collection using two methods. The first method uses the pInfos[…] syntax to retrieve the entire object located in the first position of the collection and place it in the pInfo object. You can now retrieve all properties from the pInfo object as usual. The second method demonstrates how to retrieve a specific property, the description, from the "merge" object in the collection using the name as the indexer.
