If you are talking about generated LinqToSql classes you should do it in a partial class



public partial class YourLinqToSqlClass : IEnumerable
{
    System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator()
    {
        //Implement...
    }

}

To make an object enumerable in C # you must implement the IEnumerable interface

public class Widget{}
public class WidgetCollection : IEnumerable<Widget>
{
    public IEnumerator<Widget> GetEnumerator()
    {
        throw new NotImplementedException();
    }

    System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator()
    {
        return this.GetEnumerator();
    }

}


As for the second part of your question, I'm not sure what you are asking or trying to do.

I'm not sure what you mean by "make my Linq for the SQL class IEnumerable". However, in your controller (assuming ASP.NET MVC) ...

WidgetDataContext dataContext = new WidgetDataContext();

var data = dataContext.Widgets.OrderBy(x => x.name);

return View(data);

In this case, the view will be able to just draw the object data

(named Model

in the view) as IEnumerable<Widget>

it can pass its path through it.

Does this mean (with Josh's answer above) the question?
