Compare string to 2 other strings

so i have this code part: 

        private int checkErrors() {
           int error = 0;
           if (!(nether.Text.Equals("true"))) { error += 1; }
           if (!(nether.Text.Equals("false"))) { error += 1; }
           if (!(fly.Text.Equals("true"))) { error += 1; }
           if (!(fly.Text.Equals("false"))) { error += 1; }
           if (!(achivments.Text.Equals("true"))) { error += 1; }
           if (!(achivments.Text.Equals("false"))) { error += 1; }
           if (!(whitelist.Text.Equals("true"))) { error += 1; }
           if (!(whitelist.Text.Equals("false"))) { error += 1; }
           if (!(pvp.Text.Equals("true"))) { error += 1; }
           if (!(pvp.Text.Equals("false"))) { error += 1; }
           if (!(commandBlock.Text.Equals("true"))) { error += 1; }
           if (!(commandBlock.Text.Equals("false"))) { error += 1; }
           if (!(spawnMonster.Text.Equals("true"))) { error += 1; }
           if (!(spawnMonster.Text.Equals("false")) { error += 1; }
           return error;
        }

but in any way it will get me that 'error = 7' because when one statement is true the other is false so my question is:

Is there a way to compare 2 strings to a third string ?

other example: i have the string userInput and i want, if userInput not equals "a" or "b" to execute error += 1;!

I suspect you're trying to find cases where it isn't "true" and it isn't "false". So something like:

if (spawnMonster.Text != "true" && spawnMonster.Text != "false")
{
    error++;
}

Alternatively, express the condition once, and apply it to all your strings:

var strings = new[] { nether.Text, fly.Text, achivments.Text, whitelist.Text
                      pvp.Text, commandBlock.Text, spawnMonster.Text };
return strings.Count(t => t != "true" && t != "false");
