Format decimal to string in correct culture info

What is the best way to format a decimal amount to string for UI display in the correct culture info?

Solution

  • Add a format to the ToString: myDecimal.ToString("#.00") or myDecimal.ToString("C").

    For a nullable decimal (decimal?) you will need to use the .Value property (myNullableDecimal.Value.ToString("C")) or cast the value to a plain (non-nullable) decimal. Be sure not to do this when the value is null or you will get an exception!

    See the documentation for Standard or Custom numeric format strings.
