However, when calling the String.Format method, it is not necessary to focus on the particular overload that you want to call. Instead, you can call the method with an object that provides culture-sensitive or custom formatting and a composite format string that includes one or more format items. You assign each format item a numeric index; the first index starts at 0. In addition to the initial string, your method call should have as many additional arguments as it has index values. For example, a string whose format items have indexes of 0 and 1 should have 2 arguments; one with indexes 0 through 5 should have 6 arguments. Your language compiler will then resolve your method call to a particular overload of the String.Format method.
