Convert a console program to a dll and preserve arguments

I have a dll that used to be a console program, it still has code to use "static Main(string[] args)" is there a way to pass args when I load the DLL?

I'm using

Assembly assembly = Assembly.LoadFrom("App.dll");
Type type = assembly.GetType("App.LoadFile");
var instance = Activator.CreateInstance(type,new string[] { filepath });

The Main method will not be called just by loading the assembly in your 2nd program. You just need to invoke the Main method on the type you have above.

Here's how you can call the static Main method from your code...

var assembly = Assembly.LoadFrom("App.dll");
var type = assembly.GetType("App.LoadFile");

var args = new string[] { filepath };

var main = type.GetMethod("Main", 
    System.Reflection.BindingFlags.Static
    | System.Reflection.BindingFlags.NonPublic
    | System.Reflection.BindingFlags.InvokeMethod
    );

main.Invoke(null, new object[] { args });
