无法将DateTime转换为字符串

Question

I'm trying to convert a DateTime to a string but actually the dt variable passed in the getFixtures method is underlined in red.

DateTime dt = DateTime.ParseExact(Calendar.SelectedDate.Value.ToString(), "ddMMyyyy",
                                  CultureInfo.InvariantCulture);
dt.ToString("ddMMyyyy");

fixtures.getFixtures(dt);

Error:

Can't convert DateTime to string.

What am I doing wrong?

Answer 1

Seems you want pass a string to the getFixtures but actually you are passing the dt which is a DateTime .

dt.ToString("ddMMyyyy"); does not change the dt to string , so you should save it's output to a string and use that string. Here is the code:

var stringDt = dt.ToString("ddMMyyyy");

fixtures.getFixtures(stringDt );

Answer 2

Your code:

dt.ToString("ddMMyyyy");
fixtures.getFixtures(dt);

If you want to pass string representation of datetime inside a method, change it to :

fixtures.getFixtures(dt.ToString("ddMMyyyy"));

Answer 3

instead of, dt.ToString("ddMMyyyy"); fixtures.getFixtures(dt); dt.ToString("ddMMyyyy"); fixtures.getFixtures(dt);

use

string dttime=dt.ToString("ddMMyyyy");
fixtures.getFixtures(dttime); 

using dt.ToString("ddMMyyyy") does not converts dt to string, it just returns a new string, dt remains datetime as it was.

This is an old way but it works. I added to the model.

private string _displayDate;

    [Display(Name="Display Date")]
    [DataType(DataType.Text)]
    public string DisplayDate
    {
        get
        {
            DateTime dt = new DateTime();
            dt = Convert.ToDateTime(_displayDate);
            return dt.ToShortDateString();
        }
        set { _displayDate = value; }

    }
