Generic conversion function doesn't seem to work with Guids

Question

I have the following code:

public static T ParameterFetchValue(string parameterKey)
{
    Parameter result = null;

    result = ParameterRepository         


        

Answer 1

How about:

T t = (T)TypeDescriptor.GetConverter(typeof(T)).ConvertFromInvariantString(text);

Works fine for Guid and most other types.
