二手代码

Hi,

i'm Working in Windows Application. I'm Developing Simple Notification System based c#.net with datetime concept. this project working in my system. i need validate datetime as dd/MM/yyyy while validate in client system error occur as string not recognized as a valid datetime. becoz client system have system formatted : dd MMMM yyyy

let me know how to accept all kind of datetime format in my project..

Used Code

public bool DateValidation(string stringDateValue)
        {
            bool A = false;
            try
            {
                CultureInfo CultureInfoDateCulture = new CultureInfo("fr-FR");
                DateTime d = DateTime.ParseExact(stringDateValue, "dd/MM/yyyy", CultureInfoDateCulture);
                A = true;
            }
            catch
            {
               
                        A = false;
            }
        

            return A;
        }

推荐答案

不要假设任何格式：只使用当前格式，这应该是用户输入的格式（因为这是他喜欢使用的）：

Don't assume any format: just use the current format and that should be what the user entered (since that's what he likes to use):

public bool DateValidation(string stringDateValue)
    {
    DateTime d;
    return DateTime.TryParse(stringDateValue, out d);
    }

或者更好的是，使用DateTimePicker并且您不需要将其验证为有效的DateTime，因为用户无法输入错误的。

Or better still, use a DateTimePicker and you don't need to validate it as a valid DateTime as the user can't enter a "bad" one.

DateTime d = DateTime.ParseExact(stringDateValue,  new string[] { "dd/MM/yyyy", "MM/dd/yyyy", "dd MMMM yyyy" }, CultureInfoDateCulture, DateTimeStyles.None);
