类型为'int'的值不能用作默认参数，因为没有标准转换来键入C＃

Question

"A value of type 'int' cannot be used as a default parameter because there are no standards conversions to type 'Reality.Game.Rooms.RoomActorType'" is there error I'm getting within my C#.exe.

The line(s) of error:

 public RoomActor GetActorByReferenceId(int ReferenceId, RoomActorType ReferenceType =    1)
    {
        lock (this.mActors)
        {
            foreach (RoomActor actor in this.mActors.Values)
            {
                if ((actor.Type == ReferenceType) && (actor.ReferenceId == ReferenceId)) /* line of error */
                {
                    return actor;
                }
            }
        }
        return null;
   }

Here's Reality>Game>Rooms>RoomActorType.cs:

namespace Reality.Game.Rooms
{
using System;

public enum RoomActorType
  {
    AiBot = 2,
    UserCharacter = 1,
  }
}

Thanks!

Answer 1

更改方法签名：

public RoomActor GetActorByReferenceId(int ReferenceId, RoomActorType ReferenceType = RoomActorType.UserCharacter)

Answer 2

RoomActorType ReferenceType = 1)

should be

RoomActorType ReferenceType = RoomActorType.UserCharacter)

or if you really want to use int do:

RoomActorType ReferenceType = (RoomActorType)1)

You can not use int as enum without casting
