I have the following code in my C# program.
DateTime dateForButton = DateTime.Now;
dateForButton = dateForButton.AddDays(-1); // ERROR: un-representable DateTime
Whenever I run it, I get the following error:
The added or subtracted value results in an un-representable DateTime.
Parameter name: value
Iv’e never seen this error message before, and don’t understand why I’m seeing it. From the answers Iv’e read so far, I’m lead to believe that I can use -1 in an add operation to subtract days, but as my question shows this is not the case for what I’m attempting to do.
