我是一个完整的C#新手，请原谅我的无知。

我正在尝试将字符串值解析为视图模型。作为 LineOne、LineTwo 和 LineThree 属性的一部分，我很难将数据库 DateTime 和 Boolean 值转换为字符串。我该怎么做呢？

private void mapChecks() 
{
    bool FoundResult = false;

    // Check if object is loaded
    if (Items.Count == 0)
    {
    //Add everything
        foreach (xtn_UnresolvedCheck check in MyChecks)
        {
                Items.Add(new ItemViewModel
                    {

                        LineOne = check.ClientName,
                        LineTwo = check.NSMDateTime,
                        LineThree = check.HaveRead,
                        MyappId = check.MonitoringID

          }
        );
    }
}

项目视图模型：

namespace App
{
    public class ItemViewModel : INotifyPropertyChanged
    {
        private int _myappId;

        public int MyappId
        {
            get
            {
                return _myappId;
            }
            set
            {
                if (value != _myappId)
                {
                    _myappId = value;
                    NotifyPropertyChanged("MyappId");
                }
            }
        }

    private bool _isFavorite;

    public bool IsFavorite
    {
        get
        {
            return _isFavorite;
        }
        set
        {
            if (value != _isFavorite)
            {
                _isFavorite = value;
                NotifyPropertyChanged("IsFavorite");
            }
        }
    }

    private string _lineOne;

    public string LineOne
    {
        get
        {
            return _lineOne;
        }
        set
        {
            if (value != _lineOne)
            {
                _lineOne = value;
                NotifyPropertyChanged("LineOne");
            }
        }
    }

    private string _lineTwo;

    public string LineTwo
    {
        get
        {
            return _lineTwo;
        }
        set
        {
            if (value != _lineTwo)
            {
                _lineTwo = value;
                NotifyPropertyChanged("LineTwo");
            }
        }
    }

    private string _lineThree;

    public string LineThree
    {
        get
        {
            return _lineThree;
        }
        set
        {
            if (value != _lineThree)
            {
                _lineThree = value;
                NotifyPropertyChanged("LineThree");
            }
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    private void NotifyPropertyChanged(String propertyName)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (null != handler)
        {
            handler(this, new PropertyChangedEventArgs(propertyName));
        }
    }
}

你应该做这个

 Items.Add( new ItemViewModel
 {

        LineOne = check.ClientName,
        LineTwo = check.NSMDateTime.ToString(),
        LineThree = check.HaveRead.ToString(),
        MyappId = check.MonitoringID
 });

利用ToString();

或转换为字符串
