Question

A follow-up question to one earlier: I’ve created an object in the Form1 : Form class with:

public struct POStruct
    {
        public List<string> staticCustInfo;
        public List<List<string>> itemCollection;
        public int testInt;
    }

    POStruct myObject = new POStruct();

However, when I try to access myObject from public void ItemSubmit_Click_1(object sender, EventArgs e) I get errors saying it’s not instantiated. I thought I already instantiated it above with the line POStruct myObject = new POStruct();?

Thanks for the help.

Answer 1

You’re instantiating POStruct, but that struct has two List<> objects that aren’t instantiated. When you instantiate myObject, you need to set these two properties to something of use, e.g.:

POStruct myObject = new POStruct();
myObject.StaticCustInfo = new List<string>();
myObject.itemCollection = new List<List<string>>();

If that doesn’t help, can you post the whole class, with event handler, the exact message, and the line of code that’s triggering the exception?
