DateTime c＃解析

Question

I try to parse DateTime.TryParse("30-05-2010"), and it throws an exception because it accepts MMddyyyy, and I need ddMMyyyy format. how can I change TryParse format?

thanks,

Dani

Answer 1

您可以使用DateTime.TryParseExact方法，它允许您指定字符串所在的确切格式

Answer 2

If you're making that adjustment because of local usage, try this:

bool success = DateTime.TryParse("30-05-2010", out dt);

Console.Write(success); // false

// use French rules...
success = DateTime.TryParse("30-05-2010", new CultureInfo("fr-FR"),
              System.Globalization.DateTimeStyles.AssumeLocal, out dt);

Console.Write(success); // true

Answer 3

maybe you can use the overload with the formatprovider.

DateTime.TryParse("30-05-2010", <IFormatProvider>)

not sure how to correctly implement it, cant test anything here, but here's more info about the iformatprovider: http://msdn.microsoft.com/en-us/library/system.iformatprovider.aspx
