How to get single value of List

I’m a new to ASPX, hope you dont mind if my problem is so simple with somebody.

I use a List<object> selectedValues;

selectedValues=...list of object(item1, item2,..)

Each object has 3 fields: id, title, and content.

foreach (object[] item in selectedValues)
{
  foreach (object value in item)
  {
    string result += string.Format("{0}    ", value);
    Textbox1.Text= result;--> all field is displayed in one Textbox.
  }
}

My problem is: how can I get the single field, I mean:

foreach (object value in item)
            {
                TextBox1.Text = id...???
                TextBox2.Text= title...???
                TextBox3.Text= content...???
}

Method 1

You can access the fields by indexing the object array:

foreach (object[] item in selectedValues)
{
  idTextBox.Text = item[0];
  titleTextBox.Text = item[1];
  contentTextBox.Text = item[2];
}

That said, you’d be better off storing the fields in a small class of your own if the number of items is not dynamic:

public class MyObject
{
    public int Id { get; set; }
    public string Title { get; set; }
    public string Content { get; set; }
}

Then you can do:

foreach (MyObject item in selectedValues)
{
  idTextBox.Text = item.Id;
  titleTextBox.Text = item.Title;
  contentTextBox.Text = item.Content;
}

Method 2

Define a class like this :

public class myclass {
       string id ;
       string title ;
       string content;
 }

 public class program {
        public void Main () {
               List<myclass> objlist = new List<myclass> () ;
               foreach (var value in objlist)  {
                       TextBox1.Text = value.id ;
                       TextBox2.Text= value.title;
                       TextBox3.Text= value.content ;
                }
         }
  }

I tried to draw a sketch and you can improve it in many ways. Instead of defining class “myclass”, you can define struct.
