Question

下面的代碼給了我一個

System.StackOverflowException {因爲當前線程堆棧溢出狀態無法計算表達式。 }

如何在我的模型裏面定義一個依賴於他人的字段？

public class User : IMandatoryFields 
{ 
    public byte Active 
    { 
     get 
     { 
      if (this.Active == 1 && this.LocalActive == 1 && this.GlobalActive == 1) return 1; 
      else return 0; 
     } 
     set { this.Active = value; } 
    } 
}

我認爲你需要一個私人財產也：

public class User : IMandatoryFields 
    { 
    private byte active; 
    public byte Active 
     { 
      get 
      { 
       if (active == 1 && this.LocalActive.HasValue && 
this.LocalActive.Value == 1 && 
this.GlobalActive.HasValue && 
this.GlobalActive.Value== 1) return 1; 
       else return 0; 
      } 
      set { active = value; } 
     } 
    } 
    public byte? LocalActive { get; set; } 
    public byte? GlobalActive { get; set; }
