The following code example accepts a PerformanceCounter category name, counter name, and instance name from the command line. It gets the InstanceDataCollectionCollection for the category, which is a collection of InstanceDataCollection objects. From that it gets the particular InstanceDataCollection for the specified counter. Then, if the instance exists, the example uses the Item property (referenced as an indexer) to obtain the associated InstanceData object.
