Let’s say I have a method that I want to make generic, and so far it had a big switch case of types.

For an simplified example,

switch (field.GetType()) {
case Type.Int: Method((int)x)...
case Type.NullInt: Method((int?)x)...
case Type.Long: Method((long)x)...

I’d like to be able to just call my GenericMethod<T>(field) instead and I’m wondering if this is possible and how would I go around doing it.

GenericMethod(field)

public void GenericMethod<T>(T field)

Can I use reflection to get a type and the pass it into the generic method somehow, is it possible to transform Type into <T>?

Can I have a method on the field object that will somehow give me a <T> type for use in my generic method?

Sorry for a confusing question, I’m not really sure how to phrase it correctly, but basically I want to get rid of switch cases and lots of manual coding when all I need is just the type (but that type can’t be passed as generic from parent class)

    You can actually use the dynamic type here for late binding of overloads. You will get a runtime error for unknown types though.

    You essentially define the function overloaded for each type. Then call the function with a dynamic and the runtime will figure out what method to call
