如何验证日期 [英] how to validate a date

问题描述

大家好，我在验证日期时遇到问题，我有一个带有jquery日历放置的文本框(tbDate)，但仍然被告知必须验证该日期，我知道了以下方法，但它似乎对我不起作用，如果还有其他方法，请提出建议和帮助，非常感谢.

Hi all, I''m having problems validating my date, I got a text box (tbDate) with a jquery calendar drop, but I''m still been told that I must validate that date, I''ve got the following method but it doesn''t seem to be working for me, if there is any other way please advise and help, thanks alot.

DateTime validate;
        if (DateTime.TryParse(tbDOB.Text, out validate))
        {
            update.Parameters.AddWithValue("@dob", tbDOB.Text);

        }
        else
        {
            Page.ClientScript.RegisterStartupScript(this.GetType(), "Window", "alert('Enter Valid Date');", true);

U Can validate your date Using Javascript with rejex expression

or if u want to validate in server side just use try.. catch.

Try

{
   Datetime myDate = Datetime.Parse(someTextBox.Text)
}

Catch (Exception ex)
{

   'Not a valid Date

'your Msg Goes Hear....
   'Do Something

}

}
