如何在C＃中确定Dictionary比较器的类型？

Question

I need to determine whether a Dictionary I receive in a function has a case-insensitive comparer.

ie. A case insensitive dictionary is declared like so:

var myDict = new Dictionary<string, decimal>(StringComparer.OrdinalIgnoreCase);

When I receive the dictionary into my function I can access the .Comparer property and check its type - however all I seem to get is -

System.Collections.Generic.EqualityComparer<string> 

How can I find out if the Comparer being used is StringComparer.OrdinalIgnoreCase?

您应该检查值，而不是StringComparer.OrdinalIgnoreCase的类型。

myDict.Comparer == StringComparer.OrdinalIgnoreCase
