c# - 无法访问已实现的属性(从接口(interface))

Question

我有一个带有属性的接口(interface):

public interface IEntityModifier
{

    ...
    bool AutoDetachOnFinished { get; set; }
    bool Finished { get; }
    ...

}

然后我实现它:

    bool IEntityModifier.AutoDetachOnFinished { get; set; }
    bool IEntityModifier.Finished { get { return this.mFinished; } }

但是当我需要在同一个类中访问 AutoDetachOnFinished 时，会弹出一个编译器错误:

    void IEntityModifier.Update(IEntity pEntity, Microsoft.Xna.Framework.GameTime pGameTime)
    {
        if (!this.mFinished)
        {
            this.Value += this.Delta * (float)pGameTime.ElapsedGameTime.TotalSeconds;

            if (this.Value >= this.Max)
            {
                this.Value = this.Max;
                this.mFinished = true;
                if (this.AutoDetachOnFinished) { /* Error Here */ }
            }
        }
    }

错误信息:

14 'MEngine.Entities.EntityModifier.SingleValueEntityModifier' does not contain a definition for 'AutoDetachOnFinished' and no extension method 'AutoDetachOnFinished' accepting a first argument of type 'MEngine.Entities.EntityModifier.SingleValueEntityModifier' could be found (are you missing a using directive or an assembly reference?)

我有两个问题:

1. 为什么如果我删除 IEntityModifier. 编译器会报错(所以 IEntityModifier.Update 会变成 Update，适用于任何已实现的方法) ？
2. 为什么我无法访问 AutoDetachOnFinished？

您已将这些实现为 explicit interface implementations ，这意味着您只能通过接口(interface)类型的变量访问它们 - IEntityModifier。

要么这样做:

if (((IEntityModifier)this).AutoDetachOnFinished)

或从实现中删除接口(interface)名称:

bool AutoDetachOnFinished { get; set; }
bool Finished { get { return this.mFinished; } }
