❔ C# Will not write to txt file

Not to sure what I did wrong as this is the first time I'm trying this. The code runs just gives (process 32508) exited with code 0. https://paste.mod.gg/duanwieezrrk/0

You're not using the streamwriter You're writing to the console

suddenly_toast•2y ago

can you point out where it is writing to console?

Angius•2y ago

suddenly_toast•2y ago

ohhh so i need a new set of write lines for the print func that say streamwriter gotcha

Henkypenky•2y ago

it's never entering this if

if (char.Equals(Option != 'Y', StringComparison.OrdinalIgnoreCase))
        {
            Manometer.Printvalues(density, interval);
        };

if (char.Equals(Option != 'Y', StringComparison.OrdinalIgnoreCase))
        {
            Manometer.Printvalues(density, interval);
        };

Angius•2y ago

That too, yeah It's trying to compare that char with a boolean

suddenly_toast•2y ago

Im not seeing why its trying to compare with a boolean?

Angius•2y ago

Option != 'Y' This results in a boolean

suddenly_toast•2y ago

yes

Henkypenky•2y ago

char.Equals doesn't have an overload for what you want

Angius•2y ago

a.Equals(b) compares char a with char b So 'a'.Equals(false) will try comparing char 'a' with boolean false

mtreit•2y ago

Isn't that char the type and not an instance?

suddenly_toast•2y ago

honestly im not sure. im still trying to learn this. So to fix would i change char to boolean or the option part to a char?

mtreit•2y ago

char is a keyword in C#

Henkypenky•2y ago

you can do char.Equsl(obj1, obj2) or Option.Equals(ob1)

mtreit•2y ago

Yeah, but that's not what the code shown is doing

Henkypenky•2y ago

yeah

mtreit•2y ago

Does that even compile?

Henkypenky•2y ago

yes cause StringComparison.OrdinalIgnoreCase is 5

suddenly_toast•2y ago

it compiled before i changed the console bits under stream writer to streawriter

mtreit•2y ago

Oh it's just treating the StringComparison like another object Equals(object a, object b)

Henkypenky•2y ago

yeah

mtreit•2y ago

So this code is clearly not doing what is intended 🙂

suddenly_toast•2y ago

yes lol i just need it to see if its y or n make it upper case then do what the y or n option is

Henkypenky•2y ago

StringComparison in char Equality is also a red flag there is no overload for char equality

suddenly_toast•2y ago

and this also brings up another question. if the y/n is not working is the m/w not working also?

Henkypenky•2y ago

i tested your code and the txt is empty so yes

suddenly_toast•2y ago

okat testing the code rn for the streamwriter problem. after that im still not sure how to fix the boolean comparisin prob

Henkypenky•2y ago

you can do:

char.Equals(obj1, obj2)

char.Equals(obj1, obj2)

obj1.Equals(obj2)

obj1.Equals(obj2)

suddenly_toast•2y ago

Program does not contain a static 'Main' method suitable for an entry point its saying that

Henkypenky•2y ago

what did you change

Henkypenky•2y ago

why are u passing a StreamWriter in the main as a parameter?

Angius•2y ago

Was about to ask

suddenly_toast•2y ago

because it did this - i sec

Henkypenky•2y ago

what you shared before was correct you just need to correct char comparison and streamwriter cause you are calling a method that prints to console not to file

si i changed the colsole to streamwriter and it was red squiogillys eveerywhere

Angius•2y ago

Because you're trying to use those methods as static

Henkypenky•2y ago

cause your variable is outputefile

Angius•2y ago

Use the StreamWriter you instantiated

Henkypenky•2y ago

Henkypenky•2y ago

don't use it as Type

suddenly_toast•2y ago

of pute output file there there we go that makes sense okay now for the if statements. when you say obj1 obj 2 is it comparing ob1 to obj 2?

Angius•2y ago

Yes

Henkypenky•2y ago

i understand what you want to do, with OrdinalIgnoreCase, but that only works for strings, there is no overload in char.Equals that takes that argument, you just compare chars. That's it

suddenly_toast•2y ago

so is obj 1 or obj 2 the master that is the one being compared too

Angius•2y ago

They're... just being compared

int a = 5;
int b = 17;

a.Equals(b); // same result
b.Equals(a); // same result

int a = 5;
int b = 17;

a.Equals(b); // same result
b.Equals(a); // same result

suddenly_toast•2y ago

okay let me try that 1 min

        {
            Console.WriteLine("Create file from data?: (Y/N)");
            Option = char.Parse(Console.ReadLine());
            Option = char.ToUpper(Option);

            if (Option != 'Y' && Option != 'N')
                Console.WriteLine("Incorrect Response, please input a correct respose (Y/N)");
        } while (Option != 'Y' && Option != 'N');


        if (char.Equals(Option, 'Y'))
        {
            Manometer.Printvalues(density, interval);
        };
        if (char.Equals(Option, 'N'))
        {
            Environment.Exit(0);
        };

        {
            Console.WriteLine("Create file from data?: (Y/N)");
            Option = char.Parse(Console.ReadLine());
            Option = char.ToUpper(Option);

            if (Option != 'Y' && Option != 'N')
                Console.WriteLine("Incorrect Response, please input a correct respose (Y/N)");
        } while (Option != 'Y' && Option != 'N');


        if (char.Equals(Option, 'Y'))
        {
            Manometer.Printvalues(density, interval);
        };
        if (char.Equals(Option, 'N'))
        {
            Environment.Exit(0);
        };

is that right?

Angius•2y ago

Yep

suddenly_toast•2y ago

thankyou

FusedQyou•2y ago

I'm surprised this is valid code

Henkypenky•2y ago

since char.Equals(obj1, obj2) evaluates object? it's valid, albeit wrong
