Check the static Nullable.GetUnderlyingType.
- If the underlying type is null, then the template parameter is not Nullable, and we can use that type directly
- If the underlying type is not null, then use the underlying type in the conversion.
Seems to work for me:
public object Get( string _toparse, Type _t )
{
// Test for Nullable<T> and return the base type instead:
Type undertype = Nullable.GetUnderlyingType(_t);
Type basetype = undertype == null ? _t : undertype;
return Convert.ChangeType(_toparse, basetype);
}
public T Get<T>(string _key)
{
return (T)Get(_key, typeof(T));
}
public void test()
{
int x = Get<int>("14");
int? nx = Get<Nullable<int>>("14");
}
