Question

exe file written in C#
which i need to return a complex return value to another C# project

Here is my code:

class Program
{
    private class MyObject
    {
        private int num;

        public int Num
        {
            get
            {
                return (this.num);
            }
            set
            {
                this.num = value;
            }
        }

        public MyObject(int num)
        {
            this.Num = num;
        }

    }

    [STAThread]
    public static MyObject Main(string[] args)
    {
        return new MyObject(5);
    }
}

this gives me the following error:
…\ConsoleApplication1.exe’
does not contain a static ‘Main’ method suitable for an entry point.

I’ve tried playing with it but i got no success in making it return a complex value.

Answer 1

You can’t do this from a Main method which is meant to be the entry point of the process.

If you’re writing code to be called directly from other code, you should almost certainly be building a Class Library project instead. You can add a reference from one application to another, but it’s unusual (at least outside unit tests). If you want to do this, you should just call a different method instead of Main. (You could have a Main method declared that way in one class, and use a different class as the “normal” entry point, but that seems pointlessly complicated.)
