decrement a foreach

[Elementary Penguin]

is there a way to decrement a foreach loop?

for example

string s = "cat";

foreach(char c in s)
//some how it goes backward here
Console.WriteLi ne(c);

and so the result would be

t
a
c

RE: decrement a foreach

You could optionally resort the string in the reverse order and then run your
foreach loop as usual. eg.

class ReversedCompare r:IComparer
{
public int Compare(object x,object y)
{
if((char)x < (char)y)
return 1;
else if((char)x > (char)y)
return -1;
else
return 0;
}
}


Array array = s.ToCharArray() ;
Array.Sort(arra y,new ReversedCompare r());
//s = new String((char[])array);

foreach(char c in array)
{
Console.WriteLi ne(c);
}
