How to set FontWeights to any value (Bold, UltraBold, ...) from C# Reflection?

Hi experts,

I have a string that contains "Bold" or "UltraBold" or something else that represents a FontWeights (in string format).
I also have an object (Type) that reprensents the "FontWeights" of a WPF control (from textblock or textbox or else)
I don't know how to set the String value to a fontweight value from reflection in C#

Any helps will be grateful,


Thanks,

Kind Regards.
