C#字串數組排序

//排序只帶字元的數組，不帶數位private   string[]   aa   ={ "a ", "c ", "b "}; Array.Sort(aa);     MessageBox.Show(aa[0]);     MessageBox.Show(aa[1]);     MessageBox.Show(aa[2]); 結果是：a,b,c

如果想實現

Array.Sort(arr);
不對!!!!!!!!!!
比如:   A1,A2,A10
用Array.Sort(arr);排出來就是
A1,A10,A2
而我要的是
A1,A2,A10

這樣就可以了： public   class   CustomComparer:System.Collections.IComparer { public   int   Compare(object   x,   object   y){ string   s1   =   (string)x; string   s2   =   (string)y; if   (s1.Length   >   s2.Length)   return   1; if   (s1.Length   <   s2.Length)   return   -1; for   (int   i   =   0;   i   <   s1.Length;   i++)   { if   (s1[i]   >   s2[i])   return   1; if   (s1[i]   <   s2[i])   return   -1; } return   0; } } 應用： string[]   str   =   new   string[]{ "A1 ", "A2 ", "A10 "}; Array.Sort(str,   new   CustomComparer()); for   (int   i   =   0;   i   <   str.Length;   i++) Console.WriteLine(str[i]);

 但是這樣不對帶有字元的字元排序。
