❔ Ignoring Main?

just starting out with c# and have a pretty basic question. Trying to just make a random array of ints and print them out.

class sorting {
    
public static void Main(string[] args) { 
        int[] numsToSort = getListOfNums();
        for (int i = 0; i < numsToSort.Length; ++i) {
            Console.WriteLine(numsToSort[i]);
        }


    }

    public static int[] getListOfNums() {
        Random rand = new Random();
        int[] numsToSort = new int[100];
        for (int i = 0; i < numsToSort.Length; ++i) {
            numsToSort[i] = rand.Next(100);
        }

        return numsToSort;

    }

}

class sorting {
    
public static void Main(string[] args) { 
        int[] numsToSort = getListOfNums();
        for (int i = 0; i < numsToSort.Length; ++i) {
            Console.WriteLine(numsToSort[i]);
        }


    }

    public static int[] getListOfNums() {
        Random rand = new Random();
        int[] numsToSort = new int[100];
        for (int i = 0; i < numsToSort.Length; ++i) {
            numsToSort[i] = rand.Next(100);
        }

        return numsToSort;

    }

}

output:

First time I see anything like that... I guess it offers some strict checks Like, in C# the naming convention is usually PascalCase, but your class has a lowercase names And, yeah, lowercase names are usually reserved for the language constructs like string, int, bool, etc The second one... could it be about your code missing a namespace?

j_uiceOP•2y ago

oh yes, if I change to class Sorting then it gets rid of one error but still warning CS7022: The entry point of the program is global code; ignoring 'Sorting.Main(string[])' entry point. let me try

Visual Studio supports writing code without a main or classes. Could do that if you're just looking to play around.

j_uiceOP•2y ago

Oh I would like a main and classes. Just trying to get this setup before getting more into it moving over from Java, but just not understanding what the issue is here

Omnissiah•2y ago

is this all of the code? or is there something above what you are showing

j_uiceOP•2y ago

this is all of it

Angius•2y ago

No other file in the project? Besides the .csproj of course

jayfromengland•2y ago

I'm struggling to reproduce that with just the code you shared.

j_uiceOP•2y ago

two empty .cs files

Angius•2y ago

Is one named Program.cs by chance?

j_uiceOP•2y ago

Angius•2y ago

huh

jayfromengland•2y ago

What are they named?

j_uiceOP•2y ago

jayfromengland•2y ago

Ahh you're in Visual Studio Code rather than Visual Studio

j_uiceOP•2y ago

yes I just went to dotnetfiddle (online ide) and it runs like I want it to

Angius•2y ago

How did you create this project? dotnet new console?

j_uiceOP•2y ago

yes

Omnissiah•2y ago

not even a using System?

Angius•2y ago

No need Global usings since .NET 6

j_uiceOP•2y ago

even with that it doesn't work

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net7.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

Angius•2y ago

Uhhhhh... A long shot, but rename the Sorting class to Program, and the sorting.cs file to Program.cs...? It shouldn't matter, since only the Main matters for the entry point, but who knows

j_uiceOP•2y ago

same thing so this seems like it might be a vs code thing?

Angius•2y ago

Shouldn't be

Omnissiah•2y ago

put an explicit entry point in the csproj... like <StartupObject>Name.Sorting.Main</StartupObject> (if i remember correctly)

jayfromengland•2y ago

When you run dotnet build is the warning displayed under "Build succeeded"?

Angius•2y ago

Or just yeet the main and use top-level statements lol

Weeeeird

Angius•2y ago

Aight, time to experiment

int[] numsToSort = GetListOfNums();
for (int i = 0; i < numsToSort.Length; ++i) {
    Console.WriteLine(numsToSort[i]);
}

static int[] GetListOfNums() {
    Random rand = new Random();
    int[] numsToSort = new int[100];
    for (int i = 0; i < numsToSort.Length; ++i) {
        numsToSort[i] = rand.Next(100);
    }

    return numsToSort;
}

int[] numsToSort = GetListOfNums();
for (int i = 0; i < numsToSort.Length; ++i) {
    Console.WriteLine(numsToSort[i]);
}

static int[] GetListOfNums() {
    Random rand = new Random();
    int[] numsToSort = new int[100];
    for (int i = 0; i < numsToSort.Length; ++i) {
        numsToSort[i] = rand.Next(100);
    }

    return numsToSort;
}

this is as proper of a code as it can be, with as few moving parts as it can have No namespace, no class, no main If that doesn't work, I'm at a loss

j_uiceOP•2y ago

error CS8802: Only one compilation unit can have top-level statements. cursed pc

Angius•2y ago

Delete all the other files you have that are empty

j_uiceOP•2y ago

omg

Angius•2y ago

Leave just Program.cs with this code

j_uiceOP•2y ago

j_uiceOP•2y ago

it was that tempCodeRunnerFile.cs i didnt make that

jayfromengland•2y ago

Oh, so deleting that fixed it? I was about to come onto that :p

j_uiceOP•2y ago

thank yall 🙂

jayfromengland•2y ago

Woohoo What was in it?

Angius•2y ago

If the file was completely empty, chances are the compiler saw it as a top-level statements entry point

j_uiceOP•2y ago

its an extension I have on vscode I guess it does that for some reason

        int[] numsToSort = new int[100];
        Console.WriteLine(numsToSort);

        int[] numsToSort = new int[100];
        Console.WriteLine(numsToSort);

jayfromengland•2y ago

Even if I try adding that file, I can't reproduce it

j_uiceOP•2y ago

I am not sure why 😄

jayfromengland•2y ago

Oooh Woohoo! Adding that code reproduces it. That makes sense You have one file with classes and one that's just standalone code. Feels weird to me to have it like that.

j_uiceOP•2y ago

thank yall for the help, I was starting to go crazy lol

jayfromengland•2y ago

It doesn't know whether to run the Main or the standalone code No worries

j_uiceOP•2y ago

Indirectly I learned about having just top level statements so that is nice

Angius•2y ago

TLS are great

jayfromengland•2y ago

I didn't know they were called "top-level statements" so I learned a thing.
