c# substring utility

[DARTHTAMPON]

Not sure if there is where I should be posting this information but here it goes (please direct me where to go if this is the wrong place)

I have a variable that looks like this

variable r00000000000000000000000000
or r10101010101010101010101010

and everytime a certain action is taken one of the 0's will change.
I need to check this against a stored variable to see if only 1 was changed.

in php i would do something like this
for ($x=0; $x<27; $x++)
if (!($variable{$x} == $storedvariable{$x}))
$changes++;

How do I do this in c#

any help or suggestions would be greatly appreciated

for(int x=0;x<27;x++)
{
if (!(variable.Substring(x,1) == storedvariable.Substring(x,1) )
changes++;
}
