Question

The code below contains a “whole bunch” of error messages, and I can’t for the life of me figure out why. I recently had to “downgrade” from VS2010 to VS2008, and have had nothing but misery since. The first few error messages are shown as comments next to where they are occurring.

Answer 1

Here is the corrected code (I have moved static member declaration in right place and corrected the _line.Splt() parameter):

//...
public static int TOPLEVEL_ID = 0;
public static int PARENT_ID = 1;
public static int SELF_ID = 2;
public static int MENU_CAPTION = 3;
public static int MENU_NAME = 4;

void buttonPopMenuItemsLU_Click(object sender, RoutedEventArgs e) {
    string fileName = @"C:\_UniClientNextGen\MenuItemsWithIDs.txt";
    using(StreamReader reader = File.OpenText(fileName)) {
        string _line = null;
        string[] strElements;
        do {
            _line = reader.ReadLine();
            strElements = _line.Split(',');
            int iTopLevelID = Convert.ToInt32(strElements[TOPLEVEL_ID]);
            int iParentID = Convert.ToInt32(strElements[PARENT_ID]);
            int iOwnID = Convert.ToInt32(strElements[SELF_ID]);
            string sMenuCaption = strElements[MENU_CAPTION];
            string sMenuName = strElements[MENU_NAME];
        } while(_line != null);
    }
}
//...
