[解决办法]
这样试试看：

string str = "this is test";
char[] cs = str.ToCharArray();
Array.Reverse(cs);
str = new string(cs);

Console.WriteLine(str);
[解决办法]
string str = "this is test";
string[] sss = str.Split(' ');
Array.Reverse(sss);
然后输出sss
[解决办法]
以空格split后，再for倒着输出
[解决办法]
如果是颠倒单词则参考如下：

C# code

string s = "this is test";string t = string.Empty;foreach (string v in s.Split(new char[] { ' ' },    StringSplitOptions.RemoveEmptyEntries))    t = v + " " + t;t = t.Trim();Console.WriteLine(t);
[解决办法]

       string str = "this is test";  
       string[] strs = str.Split( ' ');
       Array.Reverse(strs);
       str = string.Join(" ",strs);
       Response.Write(str);
