If you have the PropertyInfo, you can check the .PropertyType; if .IsValueType is true, and if Nullable.GetUnderlyingType(property.PropertyType) is null, then it is a non-nullable value-type:

        if (value == null && property.PropertyType.IsValueType &&
            Nullable.GetUnderlyingType(property.PropertyType) == null)
        {
            throw new InvalidCastException ();
        }
