How can I get a folder (in my project) from string? (C#)

Question

What I mean is, if I were to have something like this tree in my project:

MyProject > MyPrograms > Program1 > DoSomething.cs
                       > Program2 > DoSomething.cs

And I wanted to execute something like this in my main program.cs:

static void Main(string[] args) {
    DoStuff("Program1"); // Program1 being a folder
}

static void DoStuff(string program) {
    new MyProject.MyPrograms.program* This being the string *.DoSomething(); // This is the line
}

How would I access the program's DoSomething by using a string? (Asuming all the programs have the same file)

(PS: I do not mean Copy to Output Directory, I really mean at runtime in the application)

If you want to choose what method or behavior you call at runtime based on a string, then try looking at interface and abstract class concepts. Based on their implementation, they can perform different functions.

interface ISomething
{
  void DoSomething();
}

class SomethingA : ISomething
{
    public void DoSomething() 
   {
     Console.WriteLine("A");
   }
}

class SomethingB : ISomething
{
    public void DoSomething() 
   {
     Console.WriteLine("B");
   }
}

In the execution, you can check for the string and create a type of the object accordingly of SomethingA or SomethingB and call the method.

 static void Main(string[] args) 
{
    ISomething obj;
    
    if(args[0] == "Program1") 
    {
     obj = new SomethingA();
    }
    else 
    {
     obj = new SomethingB();
    }        

    obj.DoSomething();        
}
