❔ Trying to run a command through C# on macOS

I'm currently utilising Jetbrains rider. My tutor has tasked me with creating a simple little C# transpiler, that will have source code, which works and builds into a CS file, after that it then needs to compile via Mono. Everything works except trying to get the csc build.cs file working.

void Build()
{
...
    Compile($"csc {buildDir}/build.cs");
}

void Compile(string command)
{
    Process.Start("csc", command);
    Environment.Exit(0);
}

void Build()
{
...
    Compile($"csc {buildDir}/build.cs");
}

void Compile(string command)
{
    Process.Start("csc", command);
    Environment.Exit(0);
}

you're specifying csc twice this will equate to running csc csc build/build.cs in the terminal

I see so i really should be doing Process.Start(command); @Pobiega ? When doing that:

no you should remove the csc from the command you are generating the first argument to process.start is the command itself, not any arguments

Oh don’t think of that x Ty
