A little help // C#

Question

hello,

can someone help me to implement these commands in C#? or other but in the same context

static string fact = "";

fact = find_str_from_to2(responseFromServer, ">", "-1<");

if (fact = 1)
then (comp = 11955|708);
else
if (fact = 2)
then (comp = 9080|55);
else
if (fact = 3)
then (comp = 1085|708);  // update..


fact must me string, because i'm getting he's value from a website....
and i need to use other string.. but i need these if conditions..

ty.
