[c#] String format currency

I have this line

@String.Format("{0:C}", @price)

in my razor view. I want it to display a dollar sign in front of the price but instead it display a pound sign. How do I achieve this?

For those using the C# 6.0 string interpolation syntax: e.g: $"The price is {price:C}", the documentation suggests a few ways of applying different a CultureInfo.

I've adapted the examples to use currency:

decimal price = 12345.67M;
FormattableString message = $"The price is {price:C}";

System.Globalization.CultureInfo.CurrentCulture = System.Globalization.CultureInfo.GetCultureInfo("nl-NL");
string messageInCurrentCulture = message.ToString();

var specificCulture = System.Globalization.CultureInfo.GetCultureInfo("en-IN");
string messageInSpecificCulture = message.ToString(specificCulture);

string messageInInvariantCulture = FormattableString.Invariant(message);

Console.WriteLine($"{System.Globalization.CultureInfo.CurrentCulture,-10} {messageInCurrentCulture}");
Console.WriteLine($"{specificCulture,-10} {messageInSpecificCulture}");
Console.WriteLine($"{"Invariant",-10} {messageInInvariantCulture}");
// Expected output is:
// nl-NL      The price is € 12.345,67
// en-IN      The price is ? 12,345.67
// Invariant  The price is ¤12,345.67

You need to provide an IFormatProvider:

@String.Format(new CultureInfo("en-US"), "{0:C}", @price)

Personally i'm against using culture specific code, i suggest doing:

@String.Format(CultureInfo.CurrentCulture, "{0:C}", @price)

and in your web.config do:

<system.web>
    <globalization culture="en-GB" uiCulture="en-US" />
</system.web>

For razor you can use: culture, value

@String.Format(new CultureInfo("sv-SE"), @Model.value)

As others have said, you can achieve this through an IFormatProvider. But bear in mind that currency formatting goes well beyond the currency symbol. For example a correctly-formatted price in the US may be "$ 12.50" but in France this would be written "12,50 $" (the decimal point is different as is the position of the currency symbol). You don't want to lose this culture-appropriate formatting just for the sake of changing the currency symbol. And the good news is that you don't have to, as this code demonstrates:

var cultureInfo = Thread.CurrentThread.CurrentCulture;   // You can also hardcode the culture, e.g. var cultureInfo = new CultureInfo("fr-FR"), but then you lose culture-specific formatting such as decimal point (. or ,) or the position of the currency symbol (before or after)
var numberFormatInfo = (NumberFormatInfo)cultureInfo.NumberFormat.Clone();
numberFormatInfo.CurrencySymbol = "€"; // Replace with "$" or "£" or whatever you need

var price = 12.3m;
var formattedPrice = price.ToString("C", numberFormatInfo); // Output: "€ 12.30" if the CurrentCulture is "en-US", "12,30 €" if the CurrentCulture is "fr-FR".

Use this it works and so simple :

  var price=22.5m;
  Console.WriteLine(
     "the price: {0}",price.ToString("C", new System.Globalization.CultureInfo("en-US")));

decimal value = 0.00M;
value = Convert.ToDecimal(12345.12345);
Console.WriteLine(".ToString(\"C\") Formates With Currency $ Sign");
Console.WriteLine(value.ToString("C"));
//OutPut : $12345.12
Console.WriteLine(value.ToString("C1"));
//OutPut : $12345.1
Console.WriteLine(value.ToString("C2"));
//OutPut : $12345.12
Console.WriteLine(value.ToString("C3"));
//OutPut : $12345.123
Console.WriteLine(value.ToString("C4"));
//OutPut : $12345.1234
Console.WriteLine(value.ToString("C5"));
//OutPut : $12345.12345
Console.WriteLine(value.ToString("C6"));
//OutPut : $12345.123450
Console.WriteLine();
Console.WriteLine(".ToString(\"F\") Formates With out Currency Sign");
Console.WriteLine(value.ToString("F"));
//OutPut : 12345.12
Console.WriteLine(value.ToString("F1"));
//OutPut : 12345.1
Console.WriteLine(value.ToString("F2"));
//OutPut : 12345.12
Console.WriteLine(value.ToString("F3"));
//OutPut : 12345.123
Console.WriteLine(value.ToString("F4"));
//OutPut : 12345.1234
Console.WriteLine(value.ToString("F5"));
//OutPut : 12345.12345
Console.WriteLine(value.ToString("F6"));
//OutPut : 12345.123450
Console.Read();
