String was not recognized as a valid DateTime.

hi sanjida,

remove static from your function and try as follows

 

use this

 

 

DateTime startDate; it is output date

string[] formats = {

"d.MM.yyyy",

"dd.MM.yyyy",

"dd.M.yyyy",

"d.M.yyyy",

"d/MM/yyyy",

"dd/MM/yyyy",

"dd/M/yyyy",

"d/M/yyyy"

}; // these you can change as per your current date

If DateTime.TryParseExact("your date", formats, CultureInfo.InvariantCulture, DateTimeStyles.None, startDate) Then

{

//out date is start date,

}

sanjida 

for check given value is a valid date value or not, we need to check the value as below

 

public bool ValidateDate(DateTime date)
{
     DateTime dt;
    if (DateTime.TryParse(date.ToShortDateString(), out dt) && date > new DateTime(1900, 1, 1))
       return true;
   else
       return false;
}
