Avoid the Convert class. Use the parsers for the type you want.

You may get an error when converting a string to a DateTime because the string format does not match the format you are using. In your case, the string "2024/22/03" is not a valid date format.

Here's how you can fix your code:

string str = "2024/03/12"; // Make sure the format is yyyy/MM/dd
DateTime Date_1 = DateTime.ParseExact(str, "yyyy/MM/dd", CultureInfo.InvariantCulture);

Make sure the date in your string is valid (the date does not exceed the number of days in the month). If you want to use a different rice purity test format, adjust the str string accordingly.

If you need more help, let me know!

DateTime.ParseExact Method (System) | Microsoft Learn[^] will do what you want:

C#

string str = "2024/22/03";

// Parse the string into a DateTime object with the specified format
DateTime dateTime = DateTime.ParseExact(str, "yyyy/dd/MM", null);

// Format the DateTime object into the desired format
string formattedDate = dateTime.ToString("yyyy/MM/dd");

Console.WriteLine("Original string: " + str);
Console.WriteLine("Formatted date: " + formattedDate);

and the output:

Original string: 2024/22/03
Formatted date: 2024/03/22

To add to what Graeme has said, a better solution is to use DateTime.TryParseExact Method (System) | Microsoft Learn[^] instead - that way you can spot errors instead of your app crashing if the data isn't in the format you expect for some reason:

C#

DateTime dt;
if (!DateTime.TryParseExact(str, "yyyy/MM/dd", CultureInfo.InvariantCulture, DateTimeStyles.None, out dt))
   {
   ... report or log the problem
   return;
   }
... dt contains a valid date set at midnight here
