c# - Need to read multiple elements from single line from a text file -

i've tried using streamwriter, readline, setting var's , if statements .contains("stuff"); can't print specific part of text

start shootergameserver.exe theisland?queryport=27015?sessionname=cain532?maxplayers=10?listen?serverpassword=12345?serveradminpassword=******** -nosteamclient -game -server -log 

i need read stuff after "sessionname", "maxplayers", "serverpassword","serveradminpassword"

i can't figure out how make split work either :(

i have 3 textboxes , numericupdown box need plug values into.

you can use c# string.split() method separate out need.

        string input = "start shootergameserver.exe theisland?queryport=27015?sessionname=cain532?maxplayers=10?listen?serverpassword=12345?serveradminpassword=******** -nosteamclient -game -server -log";         string[] parts = input.split('?', ' '); // split string '?' , ' '         string output = "";         foreach(var part in parts)         {             if(part.startswith("serveradminpassword")) // put looking here                 output = part.split('=')[1]; // right side of '='         }         console.writeline(output);
