{class Program{static void Main(string[] args){StringBuilder s = new StringBuilder("hello,world!");Console.WriteLine(s);//Length属性Console.WriteLine("s.Length={0}", s.Length);//Chars属性for (int i = 0; i < s.Length; i++)Console.Write(s[i] + " ");Console.WriteLine();//Capacity属性
            Console.WriteLine(s.Capacity);}}

namespace StringBuilderTest
