WPF C # How to validate textbox input as date format

I have text boxes where the user enters a date or time. When I save to the database, I create

string input = txtdocumentiDate.Text +" "+ txtdocumentiTime.Text;
        ts.Documenti = DateTime.ParseExact(input, "dd/MM/yyyy HH.mm", CultureInfo.InvariantCulture);

(ts is my entity database database)

I would like to make a check to check if all my textbox formats are valid before saving the save button.

Use DateTime.TryParse

. It returns a bool value indicating whether the method was able to parse the string or not.



string input = txtdocumentiDate.Text +" "+ txtdocumentiTime.Text;
DateTime dummy;
if(DateTime.TryParse(input, dummy))
    ts.Documenti = DateTime.ParseExact(input, "dd/MM/yyyy HH.mm", CultureInfo.InvariantCulture);
