The MemberInfo.DeclaringType property retrieves a reference to the Type object for the type that declares this member. A member of a type is either declared by the type or inherited from a base type, so the Type object returned by the MemberInfo.DeclaringType property might not be the same as the Type object used to obtain the current System.Reflection.MemberInfo object.

• If the Type object from which this MemberInfo object was obtained did not declare this member, the MemberInfo.DeclaringType property will represent one of its base types.

• If the MemberInfo object is a global member (that is, if it was obtained from the Module.GetMethods method, which returns global methods on a module), the returned MemberInfo.DeclaringType will be null.

The following example demonstrates the difference between the MemberInfo.DeclaringType and MemberInfo.ReflectedType of a member.

using System;
using System.Reflection;

public class BaseClass {
   public void ReflectedMethod() {}
}

public class DerivedClass: BaseClass {}

public class DeclaringTypeExample {
   public static void Main() {
    Type t = typeof(DerivedClass);
    MemberInfo [] memInfo = t.GetMember("ReflectedMethod");
    Console.WriteLine("Reflected type is {0}.", memInfo[0].ReflectedType);
    Console.WriteLine("Declaring type is {0}.", memInfo[0].DeclaringType);    
   }
}
   

The output is
