Convert 24-hour String to DateTime-CodePudding

I have a string containing the date and time

string startDate = "30-09-2022 09:00:00";
DateTime startdate = DateTime.ParseExact(startDate, "dd/MM/yyyy HH:mm:ss", CultureInfo.InvariantCulture);

I want to convert to DateTime, but it doesn't work and the error message is System.FormatException: String '30-09-2022 09:00:00' was not recognized as a valid DateTime

How to solve it?

Note: the string is in 24-hour format

CodePudding user response：

The "Exact" in ParseExact() means it... your format string much match the data perfectly. For example, you can't use / if the data has -.

DateTime startdate = DateTime.ParseExact(startDate, "dd-MM-yyyy HH:mm:ss", CultureInfo.InvariantCulture);

CodePudding user response：

Your date string has '-' between the date elements and your format string has '/' slashes. This is not an exact parse.

string startDate = "30-09-2022 09:00:00"; DateTime startdate = DateTime.ParseExact(startDate, "dd-MM-yyyy HH:mm:ss", CultureInfo.InvariantCulture);

string startDate = "30/09/2022 09:00:00"; DateTime startdate = DateTime.ParseExact(startDate, "dd/MM/yyyy HH:mm:ss", CultureInfo.InvariantCulture);
