C# Currency to string

Question

I am querying a database field that returns a money value, I am assigning this to a string but it is adding extra 00 on the end.

e.g. Query returns 30.00

Answer 1

The Money data type has a precision of 4 decimal places. You'll need to either specify the format in the ToString() arguments or you can round off the value before converting to a string.

If you use .ToString() you're not getting any rounding as far as I know. I think you just lose the digits.

If you round, you're not just chopping off digits. Here's a sample for rounding (untested code):

string value = Math.Round(ReturnValue, 2).ToString();
