Alternative to IndexOutOfRangeException

[Magnus.Moraberg]

Hi,

I have the following methods -

public MyClass this[int index]
public MyClass this[string myClassName]

if this[int index] recieves an index which is outside the bounds of
the concerned array, I throw - IndexOutOfRangeException

What exception should I throw if no object in the concerned array has
the name myClassName, for this[string myClassName]?

Thanks,

Barry.

If you're using the string myClassName as a key to your collection,
you can use the KeyNotFoundException.
