实验StringBuilder类实现字符反转

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string  x = Console.ReadLine();
Console.WriteLine(Reverse(x));
Console.ReadKey();
}
public static string Reverse(String str)
{
StringBuilder strBu = new StringBuilder();
char[] c=str.ToCharArray();

for (int i = 0; i <c.Length; i++)
{
strBu.Append(c[c.Length-i-1]);
}
return strBu.ToString();
}

}
}
