C# : Convert datetime from string with different format

问题

If my string is 26/01/2011 00:14:00 but my computer set United state format (AM:PM) How to convert my string into Datetime? I try Convert.ToDateTime() but it cause error.

回答1:

As the others have said, you can use DateTime.TryParseExact, but you also seem to have a European culture format in your date. It might not hurt to make an attempt to use that to perform the conversion:

CultureInfo enGB = new CultureInfo("en-GB"); 
string dateString;
DateTime dateValue;

// Parse date with no style flags.
dateString = "26/01/2011 00:14:00";
DateTime.TryParseExact(dateString, "g", enGB, DateTimeStyles.None, out dateValue);

回答2:

Use DateTime.ParseExact or DateTime.TryParseExact. If you have to accept multiple possible datetime formats, both of those methods have overloads that take an array of format strings.

As far as that format, it looks like "dd/mm/yyyy HH:MM:ss"

I use DateTime.Tryparse - that way you can catch and handle a failure gracefully:
