Format decimal to string in correct culture info

Question

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

Loading nHibernate object from database, property is decimal and when call toString() it does format with correct decimal places. However when saving setting the same property from text eg. allocation.Price = Decimal.Parse(price, CultureInfo.CurrentCulture); but once this is set and call allocation.Price.toString() decimal places not added. eg after decimal parse 15 want 15.00 but toString just gives 15. Strange? — c00ke, Feb 26 '10 at 13:04

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.

nHibernate property was Decimal? therefoer the format option was not available on toString method. Now creating decimal variable and using your answer and works a treat. cheers! – c00ke Feb 26 '10 at 13:34
if it's a Nullable then you could either user the .Value property or cast to decimal (if you are sure it's not null) – Hans Keﬆing Feb 26 '10 at 15:10

Why not decimalVar.ToString("F2", CultureInfo.CurrentCulture);. For format strings (the "F2" part) and what they do, see Standard Numeric Format Strings and Custom Numeric Format Strings

Also, if you want to use a culture specified by the user you can use:


string userInfo = "en-US";

yourDecimal.ToString("N2", CultureInfo.CreateSpecificCulture(userInfo));

or

yourDecimal.ToString("N2", new CultureInfo(userInfo));

so what? He is not asking for dynamic cultureInfo. – NetSide Feb 26 '10 at 13:31
JavaScript is not 'Global' aware, so I used .ToString("#.00", New CultureInfo("en-GB", False)) – Zymotik Mar 28 '12 at 13:52
