Question

I have a static class that looks like this:

namespace Argus
{
    static class Argus
    {
        public static List<Branch> myArgus;
    }
}

and elsewhere in my code I have this:

// Add this branch to myArgus
Argus.myArgus.Add(branch);

When I run the code, I get this error:

Object reference not set to an instance of an object.

I have verified that branch is valid (it’s an object of the Branch class), and have no idea what could be wrong here. I’m trying to read branch data in from a text file.

You need to instantiate it; it’s default value is null otherwise:

public static List<Branch> myArgus = new List<Branch>();
