Issues related to ToString ("C2") when transferring RMB amount

We often encounter the conversion of a number to an amount string, which is simple, such as:

1 class Program2     {3         Static voidMain (string[] args)4         {5             Doublenum =123.456;6             stringNUM1 = num. ToString ("C2");7 Console.WriteLine (NUM1);8 Console.read ();9         }Ten}

where "C" is the amount of the transfer, "2" is the precision that represents the two digits after the decimal point is reserved.

The result is

However, the actual process we write, the customer encountered a problem, that is, in their, with the same code, the result is:

Finally, it is found that the ToString () method has an overload of two parameters, which is given by the official:

1 //2         //Summary:3         //converts the numeric value of this instance to its equivalent string representation, using the specified format and culture-specific format information. 4         //5         //Parameters:6         //format:7         //a numeric format string. 8         //9         //provider:Ten         //An object that provides culture-specific formatting information.  One         // A         //return Result: -         //The string representation of the value of this instance, as specified by format and provider.  - [SecuritySafeCritical] the          Public stringToString (stringFormat, IFormatProvider provider);

So, if we give only one parameter, the second parameter takes the local default value, and this value is related to some parameter settings in the operating system. If we can give the second parameter, we can guarantee to convert to RMB in any operating system, the improved code is

1 class Program2     {3         Static voidMain (string[] args)4         {5             Doublenum =123.456;6             stringNUM1 = num. ToString ("C2", CultureInfo.CreateSpecificCulture ("ZH-CN")));7 Console.WriteLine (NUM1);8 Console.read ();9         }Ten}
