任务正在重置条目中的参数

Question

我在Task的入口处有一个Task，将EditorText设置为空字符串。我正在使用FreshMvvm。您能否解释为什么在Task DecreaseDate EditorText条目中设置了条目？

以下内容在DayLogPageModel.cs中

    async Task DecreaseDate()
    {
        _dayLogs.SetLog(_logDate.ConvertToIntShort(), EditorText);

        _logDate.AddDays(-1);
        LogDateString = _logDate.ConvertToStrShort();
        EditorText = _dayLogs.GetLog(_logDate.ConvertToIntShort());
    }
    private string _editorText;
    public String EditorText
    {
        get => _editorText;
        set
        {
            _editorText = value;
            RaisePropertyChanged("EditorText");
        }
    }

这是DayLogPage.xaml
