Question

I want to identify all delegates of a class using reflection. I don’t want to invoke them, just identify. I suppose that I may use getMembers() like that :

Type t = myType;
MemberInfo[] mia = t.GetMembers(BindingFlags.Static | BindingFlags.Public | BindingFlags.NonPublic).OrderBy(item => item.Name).ToArray();
foreach (MemberInfo m in mia)
{
    //Find delegates
}

EDIT : Delegate example :

class ClassTest
{
    public delegate void SampleEventHandler(object sender, EventArgs e);
}

It’s possible with this method, or another ?

Thanks for your answers!

Answer 1

A delegate is just a (special, compiler-generated) class, that may be declared inside a class as a nested type – but bear in mind that they may also be declared directly in a namespace, like normal classes.

This will find you all nested types in a given type t, that are delegates:

private IEnumerable<Type> DelegatesDefinedInType(Type t) 
{
    var nestedTypes = t.GetNestedTypes();    
    return nestedTypes.Where(typeof(Delegate).IsAssignableFrom);
}
