Hi,

Please refer below code.

DateTime dateformat;
DateTime date;
if (string.IsNullOrEmpty(TxtDate.Text))
{
    date = DateTime.MinValue;
}
else
{
    if (DateTime.TryParseExact(TxtDate.Text, "dd-MMM-yyyy", null, DateTimeStyles.None, out dateformat) == false)
    {
        lblErrMsg.Text = "Enter valid Txtdate";
        return;
    }
    else
    {
        date = DateTime.Parse(TxtDate.Text);
    }
}

I hope this will help you out.
