C# ToString("#.00") removes my first value [closed]

I pass 0,00 to ToString("#.00") and it gives me .00 instead while i need it to be 0.00.

Solution 1:

Yes, that's working as intended. As per the documentation, the # format specifier means:

Replaces the "#" symbol with the corresponding digit if one is present; otherwise, no digit appears in the result string.

Note that no digit appears in the result string if the corresponding digit in the input string is a non-significant 0. For example, 0003 ("####") -> 3.

If you want a result of 0.00, use a format string of "0.00".

The 0 format specifier is documented (in the summary table):

Replaces the zero with the corresponding digit if one is present; otherwise, zero appears in the result string.

There are more details in the specific sections for the "#" custom specifier and the "0" custom specifier.
