MorryMarOP•10mo ago

Angius•10mo ago

Well, what does it say?

so for every code file i need to make a new project?

Angius•10mo ago

What does the error say For every program you need a new project

You can have many files within one project, yes

MorryMarOP•10mo ago

how then

Angius•10mo ago

But those files must be a part of the same program

And only the entry file can have top-level code All other files must be classes (or structs or records or enums)

MorryMarOP•10mo ago

oh well thats a bit sad

but then how do i launch a specific code?

MorryMarOP•10mo ago

when i launch it launches the main 1 or do i have to invoke it in the main one?

Angius•10mo ago

You launch the project That executes your entry file There can only ever be a single entry point in a project So... you don't

MorryMarOP•10mo ago

well b r u h my brain is dying

Angius•10mo ago

If you want to create a new program, create a new project You can use some tricks, of course

MorryMarOP•10mo ago

like i wanted to make a folder inside it all the codes i have made within a course

Angius•10mo ago

For example something like

// ProgramOne.cs
static class Foo
{
    public static void Run()
    {
        // some code
    }
}

// ProgramOne.cs
static class Foo
{
    public static void Run()
    {
        // some code
    }
}

// ProgramTwo.cs
static class Bar
{
    public static void Run()
    {
        // some code
    }
}

// ProgramTwo.cs
static class Bar
{
    public static void Run()
    {
        // some code
    }
}

// Program.cs
Console.WriteLine("Select program to run");
switch (Console.ReadLine())
{
    case "one":
        Foo.Run();
        break;
    case "two":
        Bar.Run();
        break;
    default:
        Console.WriteLine("No such program");
        break;
}

// Program.cs
Console.WriteLine("Select program to run");
switch (Console.ReadLine())
{
    case "one":
        Foo.Run();
        break;
    case "two":
        Bar.Run();
        break;
    default:
        Console.WriteLine("No such program");
        break;
}

each "codes" probably equates to the need for an individual project for each, if they are all simple console applications. from what I am gathering.

Angius•10mo ago

Yeah, most likely

MorryMarOP•10mo ago

yea

Angius•10mo ago

You can group multiple projects into a single solution if you want

MorryMarOP•10mo ago

how o

Angius•10mo ago

dotnet new sln -n MyCoolSolution dotnet sln MyCoolSolution.sln add MyCoolProject/MyCoolProject.csproj First command creates a solution file Second adds a project to the solution The structure would be like so

MyCoolThing
|— MyCoolThing.sln
|— ProjectOne
|  |— ProjectOne.csproj
|  \— Program.cs
|— ProjectTwo
|  |— ProjectTwo.csproj
|  \— Program.cs

MyCoolThing
|— MyCoolThing.sln
|— ProjectOne
|  |— ProjectOne.csproj
|  \— Program.cs
|— ProjectTwo
|  |— ProjectTwo.csproj
|  \— Program.cs

MorryMarOP•10mo ago

o okokokok thanks

z0mb•10mo ago

To add onto that, when you try to run it you just need to specify which project you are trying to run, as there are obviously multiple.

MorryMarOP•10mo ago

// Program.cs
Console.WriteLine("Select program to run");
switch (Console.ReadLine())
{
    case "one":
        Foo.Run();
        break;
    case "two":
        Bar.Run();
        break;
    default:
        Console.WriteLine("No such program");
        break;
}

// Program.cs
Console.WriteLine("Select program to run");
switch (Console.ReadLine())
{
    case "one":
        Foo.Run();
        break;
    case "two":
        Bar.Run();
        break;
    default:
        Console.WriteLine("No such program");
        break;
}

with this right?

Angius•10mo ago

No This is a workaround if you wanted to keep just a single project With mutliple projects you... run the given project cd ProjectOne && dotnet run is the easiest IMHO

z0mb•10mo ago

agreed ^

Angius•10mo ago

But you can dotnet run --project ProjectOne/ProjectOne.csproj From the solution level

z0mb•10mo ago

Alternatively if you have Visual Studio Community Edition or something of the likes you can easily select the startup project from a GUI. I don't typically use vscode otuside of front end stuff, but there's probably a way there as well

MorryMarOP•10mo ago

man thats alot of stuff

MorryMarOP•10mo ago

but now i get the idea

MorryMarOP•10mo ago

thanks :D

z0mb•10mo ago

No need to have Program2.cs and Program.cs. If you create two different csproj you can have Program.cs that is associated to each project like @ZZZZZZZZZZZZZZZZZZZZZZZZZ displayed This is a pretty standard approach and should be followed That way you don't end up with Program49.cs at some point, lol

so like u dont have to create an extra file to put the same code ? but copy and paste it into another :Ok:

z0mb•10mo ago

I'm not sure I follow the question

MorryMarOP•10mo ago

like u dont manually make a new file but the vsc does it for u man i suck at explaining stuff

z0mb•10mo ago

If you create a project within the sln, it should provide you with a Program.cs file tied to that project you created. There's two different approaches you can take. 1) One sln, multiple projects (each with their own Program.cs file). 2) One sln, one project, multiple classes, and your Program.Cs controls which one you wish to run.

MorryMarOP•10mo ago

hm ok i think all of those methods come to me in the future right xD bc it will be hard to remember all of them

So really at this point you just need to decide which approach you want to take, and if you have questions we can help with the decided upon approach. But we need to know which one you are wishing to proceed with

the most useful to be honest to follow a course is the point 2

MorryMarOP•10mo ago

to not get stuck in tutorial hell?

z0mb•10mo ago

If you wish to start with approach 2 that will work, so you have a sln created with a single project already?

So with this, you only need one Program.cs then you can create a new class that will be resposnbile for each lesson. So you may have: Program.cs Lesson1.cs Lesson2.cs Lesson3.cs etc... Or name them however you see fit It may make sense to put like lessons into folders as well, if you'd like

MorryMarOP•10mo ago

wdym? like every cs file into a folder?

z0mb•10mo ago

Just providing options, but maybe something like this...

MyLessons
|— MyLessons.sln
|— Loops
|  \— ForLoop.cs
|  \— WhileLoop.cs
|— Files
|  \— OpenFile.cs
|  \— ReadFile.cs

MyLessons
|— MyLessons.sln
|— Loops
|  \— ForLoop.cs
|  \— WhileLoop.cs
|— Files
|  \— OpenFile.cs
|  \— ReadFile.cs

Or however your course is structured.

z0mb•10mo ago

Really how you organize it is up to you, I can't decide that for you, but just providing the option that you can create a folder to hold like items together. Ultimately each lesson is it's own .cs file and can be organized as you see fit
