I am using the following code to read the schema of a fixed length file from an xml settings file. However when I try to compile I get the following error
The type or namespace name 'Field' could not be found (are you missing a using directive or an assembly reference?)      
Here is the code
private static List<Field> GetFields()
        {
            List<Field> fields = new List<Field>();
            XmlDocument map = new XmlDocument();
            string appPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
            //Load the mapping file into the XmlDocument
            map.Load(appPath + "\\CMDCSImportCSV_Settings.xml");

            //Load the field nodes.
            XmlNodeList fieldNodes = map.SelectNodes("/FileMap/Field");

            //Loop through the nodes and create a field object
            // for each one.
            foreach (XmlNode fieldNode in fieldNodes)
            {
                Field field = new Field();

                //Set the field's name
                field.Name = fieldNode.Attributes["Name"].Value;

                //Set the field's length
                field.Length =
                     Convert.ToInt32(fieldNode.Attributes["Length"].Value);

                //Set the field's starting position
                field.Start =
                      Convert.ToInt32(fieldNode.Attributes["Start"].Value);

                //Add the field to the Field list.
                fields.Add(field);


            }

            //Return the fields – this is now our map of how the flat
            // file is laid out.
            return fields;
        }

Any ideas?
Thanks,
Aditya

Have you defined a class named Field in your project?

Not really...  I have no idea what the field class is supposed to represent. Did you copy/paste this code from somewhere? If so, perhaps they have a definition of the Field class.

Yes I got this code from the web. The Field class contains three attributes namely Name,Start and Length.

You need to copy that class into your project. Your error is because the compiler doesn't know what the definition of Field is because it currently does not exist in your project. Add a new code file to your project and paste the definition of Field into it.
