C# 基于主状态枚举的绑定子状态枚举

我试图基于主状态将标签值绑定到子状态枚举。每个主状态都有不同的子状态枚举，这就是为什么当主状态更改时，我需要将标签重新绑定到不同的子状态枚举。但我如何做到这一点是相应的XAML代码

这是包含3个状态枚举（1个主状态和2个子状态）的类

因此，当

当前状态

更改为

校准

时，我想绑定到子状态项

校准跟踪状态

，当

当前状态

更改为

回家

时，我想绑定到子状态项

回家状态

这是我到目前为止的XAML代码：

<Label>
    <Label.Content>
        <TextBlock>
            <TextBlock.Text>
                <MultiBinding StringFormat="{}{0} - {1}">
                    <Binding Path="motor.CurrentState"/>
                    <Binding Path="motor.xxx"/>
                </MultiBinding>
            </TextBlock.Text>
        </TextBlock>
    </Label.Content>
</Label>

当校准的主状态为

且校准的子状态为
SUB_STATE_C1
时，请按照以下步骤操作

在ViewModel中创建名为“SubState”的字符串属性，并将其绑定到标签，如下所示

  private string _subState;    
  public string SubState    
  {
     get { return _subState; }
     set { _subState = value; OnPropertyChanged(); }
  }

          public List<STATE> States { get; set; }
          States = new List<STATE>
          {
              STATE.IDLE,
              STATE.CALIBRATE,
              STATE.GO_HOME
          };


更新xaml以绑定到子状态字符串属性

<Label Content="{Binding SubState}" />


下面是我的ViewModel的SetState方法

      public void SetState(object selectedState)
      {
          if(selectedState.ToString() == STATE.IDLE.ToString())

              };

              SubState = CurrentState.ToString();
          }



          public void SetState(object selectedState)
          {
              if(selectedState.ToString() == STATE.IDLE.ToString())
              {
                  SubState = CurrentState.ToString();
              }
              else if(selectedState.ToString() == STATE.CALIBRATE.ToString())
              {

          {
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
          }

          public event PropertyChangedEventHandler PropertyChanged;
      }


声明列表并绑定到组合框，并在ViewModel构造函数中初始化States List对象，如下所示

  private string _subState;    
  public string SubState    
  {
     get { return _subState; }
     set { _subState = value; OnPropertyChanged(); }
  }

          public List<STATE> States { get; set; }
          States = new List<STATE>
          {
              STATE.IDLE,
              STATE.CALIBRATE,
              STATE.GO_HOME
          };

公共列表状态{get；set；}
国家=新名单

};

注意：-MainVM是我的ViewModel，我个人认为Motor类应该只包含数据成员，而不包含任何属性更改事件或与VM相关的其他事情。因此，我已将某些项从Motor类移动到ViewModel
