How to get methods in a type

Question

Given: System.Type instance.

The aim is to get the newly-introduced methods (i don't know the right word) in the type, which are - not inherited - not overridden

I want to use .NET Reflection and I tried the Type.GetMethods() method. But, it returned even inherited and overridden ones.

I thought of filtering after getting all the methods. And I looked at the properties/methods exposed by MethodInfo class. I could not figure how to get what I wanted.

For instance: I have a class, class A { void Foo() { } }

When I invoke typeof(A).GetMethods() , I get Foo along with the methods in System.Object: Equals, ToString, GetType and GetHashCode. I want to filter it down to only Foo.

Does anyone know how to do this?

Thanks.

Answer 1

GetMethods has an overload that lets you specify BindingFlags. E.g. so if you need to get all declared, public, instance methods you need to pass the corresponding flags.

var declaredPublicInstanceMethods = 
    typeof(A).GetMethods(BindingFlags.DeclaredOnly | BindingFlags.Public | BindingFlags.Instance);

I hope this was what you want

var methods = typeof(MyType).GetMethods(System.Reflection.BindingFlags.DeclaredOnly);

Answer 3

try this

typeof(Foo).GetMethods(BindingFlags.Public|BindingFlags.Instance|BindingFlags.DeclaredOnly)

You can filter the returned MethodInfo collection by DeclaringType:

var methods = typeof(A).GetMethods().Where(mi => mi.DeclaringType== typeof(A));
