❔ method

Hello, If I create a method, does the method know about things in the Main method? Or am I supposed to tell the method?

it will not "know" about things in other methods

palekfOP•2y ago

how to tell

Pobiega•2y ago

you'll get compilation errors? 🙂

how to import a int/string in a other method

Doombox•2y ago

public void DoThing(string someValue){ } pass what you want to use in the method as a parameter

ero•2y ago

arguments

palekfOP•2y ago

thank you @Ero @Task.WhenAll

ero•2y ago

they meant "how to tell the method about the variable" not "how to tell that it doesn't work"

Pobiega•2y ago

palekfOP•2y ago

thank you too

ero•2y ago

what are those warnings though

Pobiega•2y ago

suggestions (var over int, public could be private). Not relevant to the topic. also, chill with the passive aggressive comments while someone is helping lol

ero•2y ago

what? what passive aggressive comments

Pobiega•2y ago

ero•2y ago

yeah that's just fact and clarification

Pobiega•2y ago

Read the initial post. I think its a good idea to show the initial state and how to fix the problem

ero•2y ago

what

palekfOP•2y ago

static public int Poop(string countPoopString) { try { int countPoopInt = Int16.Parse(countPoopString); } catch { Console.WriteLine("Konverting dont available"); } return countPoopInt ; }

odd method name there

palekfOP•2y ago

where

TheRanger•2y ago

u called ur method Poop

palekfOP•2y ago

yes

TheRanger•2y ago

which means this 💩

palekfOP•2y ago

and? its dor testing for

TheRanger•2y ago

so im saying its odd, u asked where

palekfOP•2y ago

what means odd

Pobiega•2y ago

weird, unusual anyways, your code has a problem.. you are declaring a variable in the try that might not succeed. countPoopInt is declared in the wrong "scope" for you to use it as the return

palekfOP•2y ago

what do you mean with scope

Pobiega•2y ago

$scopes

MODiX•2y ago

scope A {
  thing a;
  scope B {
    thing b;
  }
}

scope A {
  thing a;
  scope B {
    thing b;
  }
}

thing a is available in scope A and scope B thing b is available only in scope B

Pobiega•2y ago

anywhere you see {, that creates a new scope } closes the current scope so the stuff inside the try is not availble outside it

palekfOP•2y ago

so how to get it outside

Pobiega•2y ago

You could split the declaration and the assignment so you declare the variable outside the try, and assign to it inside. you'll need to give it a default value thou, in case the try fails

palekfOP•2y ago

static public int Poop(string countPoopString) {
int countPoopInt           
try {
                int countPoopInt = Int16.Parse(countPoopString);
             }
         catch {
                Console.WriteLine("Konverting dont available");
               }
            return countPoopInt ;
        }

static public int Poop(string countPoopString) {
int countPoopInt           
try {
                int countPoopInt = Int16.Parse(countPoopString);
             }
         catch {
                Console.WriteLine("Konverting dont available");
               }
            return countPoopInt ;
        }

Pobiega•2y ago

better, but you have duplicate declarations now

TheRanger•2y ago

Int16 btw

Pobiega•2y ago

Ah yes, don't use that. just int.Parse instead

palekfOP•2y ago

TheRanger•2y ago

int CountPoopInt; // this is a declaration
CountPoopInt = 1; // this is an assignment
int CountPoopInt = 1; // this is a declaration and assignment combined

int CountPoopInt; // this is a declaration
CountPoopInt = 1; // this is an assignment
int CountPoopInt = 1; // this is a declaration and assignment combined

palekfOP•2y ago

that I know, but the parse is not recocnized now

TheRanger•2y ago

how so? u need to tell us what error messages u see and show us ur current code

palekfOP•2y ago

the name "int" isnt there in the actual konext

TheRanger•2y ago

copy paste the error message

palekfOP•2y ago

Im a german so the error message is in german

TheRanger•2y ago

doesnt matter, i can see the error code number

palekfOP•2y ago

CS0103

TheRanger•2y ago

error message can help too since it can tell which variable it has the issue with and show ur current code

palekfOP•2y ago

ok wait

static public int Poop(string countPoopString) {
            int countPoopInt;
            try {
                int countPoopInt = Int.Parse(countPoopString);
             }
         catch {
                Console.WriteLine("Konvertierung nicht möglich");
               }
            return countPoopInt;
        }
    
    }

static public int Poop(string countPoopString) {
            int countPoopInt;
            try {
                int countPoopInt = Int.Parse(countPoopString);
             }
         catch {
                Console.WriteLine("Konvertierung nicht möglich");
               }
            return countPoopInt;
        }
    
    }

TheRanger•2y ago

its int.Parse(countPoopString); not Int.Parse(countPoopString); i is small

palekfOP•2y ago

oh yeah Ill be away for a short time, thank you
