Question

Consider the following code:

class Program 
{

    static void Main(string[] args)
    {
        new Program().Run(args);
    }

    void Run(string[] args)
    {
        ...
    }

    ...
}

Now this works as I expect it to, and certainly I can’t see anything obviously wrong, but instinctually this code worries me. So I have three questions:

• Is this behavior well defined by the compiler?
• Is this code doing what I expect it to?
• Is this code in keeping with best practices?

Answer 1

Yes, this is valid code and does what you expect it to do.

Main is just a static method. The fact that it is the entry point, just means that the CLR calls it at startup. It is perfectly valid to instantiate a class in a static method, and call methods on it.
