Having a problem with a list<> of objects - any ideas?

[Paul Johnson]

Hi,

I have a class which looks like this (the class is then used to read back from a webservice)

class fred
{
  string jim;
  string hilda;
  int eccles;
  bool crunn;
  double vodka;
}

Elsewhere in my code I have the following

public void doSomething()
{
  List<fred> chunky = new List<fred>();
  try
  {
     webservice r = new webservice();
     chunky = r.returnedList;
     // do something
  }
  catch (System.Exception o) 
  {
    fred[0].jim = o.ToString();
    // do something else
  }
}

Problem is coming from the catch. AIUI, what I've done is correct as I've instantated a new list. OK, it doesn't contain anything at the top, but the way I've addressed the list should be correct - but it dies the code dies at the adding of the line.

Do I need to have a line at the top of the code that says

chunky = null;

before I can do something like this? I obviously can't use chunky.Add(o.To String()); here as the poor compiler won't know what in the generic list has to have the string added to it...

Any help here would be appreciated.

first, some obvious errors.

 string jim;
 string hilda;
 int eccles;
  bool crunn;
  double vodka;

these varibles' accessing authority is private. so fred's object can't access them.

second, when you use chunky.Add( ),
the transferred parameter shouble be fred's object.

does this return a list of fred: r.returnedList?

i'm not native speaker, hope make myself clear!

FYI: struct is enough for you to orangnize your data.

try this and I have tested on my VS

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
 

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            List<fred> chunky = new List<fred>();
            fred test1 = new fred();
            test1.jim = "Jim";
            test1.eccles = 0x01;
            test1.crunn = true;

            chunky.Add(test1);
        }

       
    }
     
               struct fred
              {
              public string jim;
              public int eccles;
              public  bool crunn;
              }

}
