This might help 

    String.Format("{#,##0.00}", 1243.50); // Outputs “1,243.50″

    String.Format("{0:$#,##0.00;($#,##0.00);Zero}", 1243.50); // Outputs “$1,243.50″ 

    String.Format("{0:$#,##0.00;($#,##0.00);Zero}", -1243.50); // Outputs “($1,243.50)″ 

    String.Format("{0:$#,##0.00;($#,##0.00);Zero}", 0); // Outputs “Zero″

myPrice.ToString("N2");

depending on what you want, you may also wish to display the currency symbol:

myPrice.ToString("C2");

(The number after the C or N indicates how many decimals should be used). (C formats the number as a currency string, which includes a currency symbol)

To be completely politically correct, you can also specify the CultureInfo that should be used.

The one you want is "N2".

Here is an example:

double dPrice = 29.999988887777666655554444333322221111; 
string sPrice = "£" + dPrice.ToString("N2");

You might even like this:

string sPrice = "";

if(dPrice < 1)
{
    sPrice = ((int)(dPrice * 100)) + "p";

} else
{
    sPrice = "£" + dPrice.ToString("N2");

}

which condenses nicely to this:

string sPrice = dPrice < 1 ? ((int)(dPrice * 100)).ToString("N0") + "p" : "£" + dPrice.ToString("N2");

As a side note, I would recommend looking into the Decimal type for currency. It avoids the rounding errors that plague floats, but unlike Integer, it can have digits after the decimal point.

Look into format strings, specifically "C" or "N".

double price = 1234.25;
string FormattedPrice = price.ToString("N"); // 1,234.25

I think this should do it:

String.Format("{0:C}", doubleVar);

If you don't want the currency symbol, then just do this:

String.Format("{0:N2}", doubleVar);
