Question

Is there a C# equivalent for the VB.NET FormatNumber function?

I.e.:

JSArrayString += '^' + (String)FormatNumber(inv.RRP * oCountry.ExchangeRate, 2); 

Answer 1

In both C# and VB.NET you can use either the .ToString() function or the String.Format() method to format the text.

Using the .ToString() method your example could be written as:

JSArrayString += '^' + (inv.RRP * oCountry.ExchangeRate).ToString('#0.00') 

Alternatively using the String.Format() it could written as:

JSArrayString = String.Format('{0}^{1:#0.00}',JSArrayString,(inv.RRP * oCountry.ExchangeRate)) 

In both of the above cases I have used custom formatting for the currency with # representing an optional place holder and 0 representing a 0 or value if one exists.

Other formatting characters can be used to help with formatting such as D2 for 2 decimal places or C to display as currency. In this case you would not want to use the C formatter as this would have inserted the currency symbol and further separators which were not required.

See ‘String.Format(‘{0}’, ‘formatting string’};‘ or ‘String Format for Int‘ for more information and examples on how to use String.Format and the different formatting options.
