performancecounters and IComparable/IComparer

Hi, I am creating an array of performancecounter objects and wondering if it
is possible to sort this array according to category Names.
I tried Array.Sort(AllCountersCategories) but it is erroring. I understood
that to be able to sort an array its contents should implement the
IComparable/IComparer interface.
So the question is how can we know if an object implements this interface or
not, the 2nd of course, any idea of how to sort this array containing
performance counters object according to category names?

Thanks

Thanks Jeroen and Cor for your replies!

Hi Salam,
Yes, you're right. A hashtable could not be sorted. To get a "sorted
hashtable", you can use System.Collections.SortedList or
System.Collections.Generic.SortedList<TKey,TValuea s Cor has suggested.

The following comments are quoted from MSDN document:

"A SortedList element can be accessed by its key, like an element in any
IDictionary implementation, or by its index, like an element in any IList
implementation. A SortedList object internally maintains two arrays to
store the elements of the list; that is, one array for the keys and another
array for the associated values."

"The elements of a SortedList object are sorted by the keys either
according to a specific IComparer implementation specified when the
SortedList is created or according to the IComparable implementation
provided by the keys themselves. In either case, a SortedList does not
allow duplicate keys."

For more information on the SortedList and SortedList<TKey,TValueclasses,
please refer to the following MSDN documents:

Hope this helps.
