c# - DateTime TryParse problem -

- 

string date = txtworkingdate.text;             datetime datetime = datetime.minvalue;              if (datetime.tryparse(date, out datetime))             {                 args.isvalid = true;             }             else                 args.isvalid = false;

txtworkingdate.text "dd.mm.yyyy" becouse of validateion false if date not "dd.mm.yyyy". how c check types of date "dd.mm.yyyy", "mm/dd/yyyy" becouse valid.

by using this overload , providing accepted formats:

string date = txtworkingdate.text; datetime datetime; string[] formats = new[] { "dd.mm.yyyy", "mm/dd/yyyy" }; if (datetime.tryparseexact(date, formats, cultureinfo.invariantculture, datetimestyles.none, out datetime)) {     args.isvalid = true; } else {     args.isvalid = false; }
