C#-StringBuilder类的使用---ShinePans

//StringBuilder
using System;
using System.Text;
class program
{
static void Main()
{
int Num = 689;
StringBuilder SBuilder = new StringBuilder("ABCD", 100);
//实例化一个StringBuilder 对象,并且将其赋值为ABCD,初始长度为100
SBuilder.Append(")abcd.");  //"abcd"添加到结尾
Console.WriteLine("Step1:"+SBuilder);

SBuilder.AppendFormat("{0:C}", Num);  //{0:C}输出元符号
SBuilder.Insert(0, "software");  //将software添加到开头,索引为0处
Console.WriteLine("Step2:"+SBuilder);

SBuilder.Remove(14, SBuilder.Length - 14);  //删去指定字符
Console.WriteLine("Step3:"+SBuilder);

SBuilder.Replace("software", "--software replaced--"); //替换指定字符
Console.WriteLine("Step4:"+SBuilder);

Console.ReadLine();
}
}
