Advanced formatting rules for StringBuilder.AppendFormat

I've seen on this site a StringBuilder code sample illustrating AppendFormat usage:

using System;
using System.Text;

class Program
{
    static int[] _v = new int[]
    {
        1,
        4,
        6
    };

    static void Main()
    {
        StringBuilder b = new 开发者_开发问答StringBuilder();
        foreach (int v in _v)
        {
            b.AppendFormat("int: {0:0.0}{1}", v,
                Environment.NewLine);
        }
        Console.WriteLine(b.ToString());
    }
}

=== Output of the program ===

int: 1.0
int: 4.0
int: 6.0

Where can I find documentation on those advanced rules for string formatting?

• Composite Formatting
• Standard Numeric Format Strings
• Custom Numeric Format Strings
• Standard Date and Time Format Strings
• Custom Date and Time Format Strings

Are you looking for this ?

You can start by checking the Composite Formatting article at MSDN. From there you will find links to standard format strings for numbers and dates, as well as links to the custom format strings for both numbers and dates.
