Immediate Interfaces for a type

If anybody is interested to get the immediate interfaces for a type, this a way to get it:

          /// <summary>
          /// Gets the immediate interfaces.
          /// </summary>
          /// <param name="type">The type.</param>
          /// <returns></returns>
          public static Type[] GetImmediateInterfaces(Type type)
          {
              Type[] interfaces = type.GetInterfaces();
              return GetImmediateInterfaces(interfaces);
          }
  
          /// <summary>
          /// Gets the immediate interfaces.
          /// </summary>
          /// <param name="interfaces">The interfaces.</param>
          /// <returns></returns>
          public static Type[] GetImmediateInterfaces(Type[] interfaces)
          {
              List<Type> immediateInterfaces = new List<Type>();
  
              foreach (Type possibleImmediateInterface in interfaces)
              {
                  bool isBaseInterface = false;
  
                  foreach (Type baseInterface in interfaces)
                  {
                      if (possibleImmediateInterface != baseInterface && possibleImmediateInterface.IsAssignableFrom(baseInterface))
                      {
                          isBaseInterface = true;
                          break;
                      }
                  }
  
                  if (!isBaseInterface)
                      immediateInterfaces.Add(possibleImmediateInterface);
              }
  
              return immediateInterfaces.ToArray();
          }
