将DateTime和Boolean转换为字符串

Question

I'm a complete C# novice, please excuse my ignorance.

I'm trying to parse string values into a view-model. I'm having difficulty converting the database DateTime and Boolean values into strings as part of the LineOne, LineTwo and LineThree properties. How do I do this?

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

          }
        );
    }
}

ItemViewModel:

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));
        }
    }
}

Answer 1

You should do this

 Items.Add( new ItemViewModel
 {

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

Answer 2

Use ToString();

or cast to string
