Getting Underlying type of generic collection by relection?

Question

Is there a simple way to get the underlying type of a generic collection using reflection? For example, if I have an IList<T>, how do I find out the type of T? The best I have been able to do so far is:

myProperty.PropertyType.UnderlyingSystemType.ToString()

 
That gives me a string like this
:

"System.Collections.Generic.IList`1[Fsm.Core.Domain.Category]"

I can then parse that string to get the underlying type ('Category' in this case).

The parsing code is an ugly hack--is there a simpler, more direct way to get the type of class T? Thanks for your help.

YOu can use

myProperty.PropertyType.BaseType.GetGenericArguments[0]

Thanks--here is the code I used:

private static string GetElementTypeName(PropertyInfo property)

{

Type[] genericArguments = property.PropertyType.GetGenericArguments();

return genericArguments[0].Name;

}
