Find underlying DataType (System Type) in the PropertyType.FullName using RegEx or Other possible way?

Question

I have some library that have some properties nullable i want to access the underlying data type of the property using Reflection.

System.Nullable`1[[System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]

How can i get they System.Int32 from RegEx??

If there any another best way to get this then it will be much better.

Do you really have to go via the string representation? If you've got the property itself, it's easy:

// This returns null if property.PropertyType isn't a Nullable<T>
Type underlyingType = Nullable.GetUnderlyingType(property.PropertyType);
