Hello All,

I need to check the string(will be passed as 'YYYYMMDD' e.g. 20170413) is future date or not. I need to make use of TryParseExact for this?

I have used

ParseExact

currently and it is working fine.

But now I have to use TryParseExact instead.

Can anyone help in this?

Thanks in advance.

If you reread your posting, you would see that it makes no sense. You used TryParseExact and it is working fine but now you have to use TryParseExact instead?

And so what is the problem? Didn't the example code for TryParseExact answer whatever your question actually is?

I guess you have used TryParse and ask how to use TryParseExact.

Read the documentation:
DateTime.TryParseExact Method (String, String, IFormatProvider, DateTimeStyles, DateTime) (System)[^].

The format string for 'YYYYMMDD' will be "yyyyMMdd".
The provider should be CultureInfo.InvariantCulture.
The style should be DateTimeStyles.None.

So use

C#

DateTime dateValue;
bool isValidDate = DateTime.TryParseExact(dateString, 
    "yyyyMMdd", 
    CultureInfo.InvariantCulture, 
    DateTimeStyles.None, 
    out dateValue);

Solution 2

You should use one of the DateTime methods, such as DateTime.Compare Method (DateTime, DateTime) (System)[^].

string d = "20170413";
            
// using ParseExact
DateTime dt1 = DateTime.ParseExact(d, "yyyyMMdd", System.Globalization.CultureInfo.CurrentCulture);

// using TryParseExact
DateTime dt2;
if (DateTime.TryParseExact(d, "yyyyMMdd", System.Globalization.CultureInfo.CurrentCulture, System.Globalization.DateTimeStyles.None, out dt2))
{
    // the conversion worked
}
else
{
    // the conversion failed
}
