问题 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 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? 回答1:
