I am working on a C# application. I want to change number decimal figure with comma(,) where i have dot(.) using regular expression.

For example:

Price= 100,00.56

As this international rule of representing numeric values but I Sweden they have different ways for numbers Like 

Price= 100.00,56

So i want to change dot(.) into comma(,) and comma(,) into dot(.) using RegEx. Could guide me about this.

When formatting numbers, you should use the string format overload that takes a CultureInfo object. The culture name for swedish is "sv-SE", as can be seen here.

decimal value = -16325.62m;
Console.WriteLine(value.ToString(CultureInfo.CreateSpecificCulture("sv-SE")));

Edit:

As @OregonGhost points out - parsing out numbers should also be done with CultureInfo.
