Unknown member error C#

I am a pretty new developer and I am trying to setup a ODS database connection. I am referencing an example from another programmers work that use to work here. Here is the code. It throws an error on after this. statement. I have my work exactly like his if you want to see his just leave comment it's several lines long.

public ODSData_Codename.TrayLabelReferenceRow toDataRow()
    {
        ODSData_Codename.TrayLabelReferenceRow row= null;
        row.LabelName = this.LabelName;
        row.LabelCode = this.LabelCode;
        row.LabelStock = this.LabelStock;

        return row;
    }
Solution

  • Are you getting a NullReferenceException, Object reference not set to an instance of an object?

    you're first line makes row point to null. null doesn't have a property of LabelName. You need to instantiate row to an object of class ODSData_Codename.TrayLabelReferenceRow

    You should look at this What is a NullReferenceException and how do I fix it?
