Populate DataTable with API results
You can pass all of the properties of your dataPull class in a single line which will also pass any future properties you decide to add to your object, using Reflection:

var values = data.GetType().GetProperties().Select(p =&gt; p.GetValue(data))
    .Concat(new object[] {gg, ff, ee, dd});
SQLHelperTable.Rows.Add(ro.Alpha, values);
