Changing a Int to a String then Formatting the String

Question

<p class="card"> Credit Limit: <b style="color: #00e500 ;"> $@Model.CreditLimit.ToString().ToLocaleString()</b> </p>

I am changing an Int to a String using ToString() Then I am trying to format the number I am getting using ToLocaleString(). The number looks like this: 80567. I am trying to format it to look like this: 80,567.

The error I get is "string does not contain a definition for "ToLocaleString"

Thoughts?

EDIT: Going to have this issue closed. Found where my error resided. Please refer to this link if you have any questions on the topic: Link to StackOverFlow issue

toLocaleString is available in other languages, not C#, unless you implement an extension method. — Yuriy Faktorovich, Aug 29 '17 at 14:03
Also, I wouldn't think ToLocaleString would be a method on a string but rather an int because what would it even do for a string like "hello world!" ? — Blake Thingstad, Aug 29 '17 at 14:04

I see that you want to show money amount, you should use currency NumberFormatInfo for this. First get current CultureInfo or create it for specific language-country:

var culture = Thread.CurrentThread.CurrentCulture;
// or
var culture = new CultureInfo("en-US");

Then use it to format your number:

var creditLimit = 100;
var creditLimitFormatted = creditLimit.ToString("c", culture);

The "c" stands for "currency", you can see other possible options in the documentation of NumberFormatInfo.

@Model.CreditLimit - this is Integer

@Model.CreditLimit.ToString() - this is a String

now you are trying to execute the ToLocaleString() which clearly from the error

"string does not contain a definition for "ToLocaleString"

To do what you want to archive try the solutions below:

String.Format("{0:n}", @Model.CreditLimit); //Output: 80,567.00

string.Format("{0:n0}", @Model.CreditLimit); // Output: 80567

That's because the int (Int32) class is not formattable, that is, it's representation does not depend on the culture, for example. You have to roll out your formatting code.

This article gives a nice overview of the different format types available. It sounds like you want the Numeric Format Specifier. You'd use it like this

int intValue = 123456789;
Console.WriteLine(intValue.ToString("N1", CultureInfo.InvariantCulture));
// Displays 123,456,789.0
