[深海之蓝]

public string change(string test)
{

char[] aa = test.ToCharArray();
char[] bb = new char[aa.Length];
string result = "";
for (int i = 0; i < aa.Length; i++)
{
bb[i] = aa[aa.Length-i-1];
result += bb[i].ToString();
}

return result;

}

.NET 2.0以前版本...

char[] cs = ss.ToCharArray();
Array.Reverse(cs);
return new string(cs);

Linq版本...

return new string(ss.ToCharArray().Reverse().ToArray())

  string ss = "xyz";
  char[] newss = ss.ToCharArray();
  for(int i=newss.Length-1;i>=0;i--)
   Console.WriteLine(newss[i]);

把字符串里的字符循环一遍重新组装一下

string ss = "xyz";
            StringBuilder strBuilder = new StringBuilder();
            foreach (char c in ss)
            {
                strBuilder.Insert(0, c.ToString());
                Console.WriteLine(strBuilder);
            }
