format factory error not recognized supported

It doesn’t take long to reach the conclusion that some strings that are perfectly valid dates in one format are not in others. Now consider this list, which shows just some of the possible ways that date can be represented, in actual date/time formats used by real people every day across the globe: (There’s nothing special about that date I got it from this Random Calendar Date Generator.) One of the ways this messiness manifests itself is through the countless date formats used around the world.įor instance, think about the date June 14th, 2019. We humans have a messy relationship with time. Did it run successfully? Or, did you get the “String was not recognized as a valid DateTime value” message?Īs it turns out, whether the code works like a charm or crashes is mostly a matter of geography.

Go ahead, create a console app and place that line of code in it. The really important piece in the last sentence was “at least to you,” as you’ll see in a second.įor instance, consider the following line of C# code: DateTime d = DateTime.Parse('') The problem is, more often than not, the offending string is something that, at least to you, looks like a perfectly normal date and time. Well, things would be a walk in the park if you got this message only when trying to parse, say, “potato” as a DateTime. It states that you’re trying to get a DateTime value out of a string that is not a valid?DateTime. I’ll concede?it: As far as error messages go, “String was not recognized as a valid DateTime” isn’t bad at all. “String Was Not Recognized as a Valid DateTime.” Why Does That Happen?
