I have a class MyGeneric<T>, and some cached data created from type MyGeneric<string>, MyGeneric<int>, MyGeneric<double>... etc.
Somewhere I have to check certain data to see if it is MyGeneric, I code like this:
if (data is MyGeneric<>) { // can't compile
// ... do something
}
or
if (data.GetType() == typeof(MyGeneric<>)
|| typeof(MyGeneric<>).isAssginableFrom(data.GetType())) {
// no exception but none of these comparison works
}
or this kind of stupid implemention works but i'd like to throw it away:
if (data.GetType().Name.StartsWith(typeof(MyGeneric<>).Name) { ... }
Is there a way to check relations between actual data type and open generic type (MyGeneric<>) ?
What you call open generic type is known as generic type definition:
if(data.GetType().GetGenericTypeDefinition() == typeof(MyGeneric<>))
{
}
