[C#] ASP.Net MVC HTML List helper

2010-01-25T23:55:23-08:00

I wanted to display list from my object:
user[x].Group[y].Name
I got some of code from here: http://blog.wekeroad.com/blog/asp-net-mvc-list-helper-extension-method/

I'm wondering if there is a better way.

public static string ToFormattedList<T>(this HtmlHelper helper, IList<T> objectList, ListType listType, Func<T, string> valueReturn)
{

    string outerListFormat = "";
    string listFormat = "";

    switch (listType)
    {
        case ListType.Ordered:
            outerListFormat = "<ol>{0}</ol>";
            listFormat = "<li>{0}</li>";
            break;
        case ListType.Unordered:
            outerListFormat = "<ul>{0}</ul>";
            listFormat = "<li>{0}</li>";
            break;
        case ListType.TableCell:
            outerListFormat = "{0}";
            listFormat = "<td>{0}</td>";
            break;
        default:
            break;
    }

    var sb = new StringBuilder();
    objectList.ForEach(item => sb.AppendFormat(listFormat, valueReturn(item)));
    return string.Format(outerListFormat, sb);
}

public enum ListType
{
    Ordered,
    Unordered,
    TableCell
}

## Usage:
Html.ToFormattedList(item.Groups, UiHelpers.ListType.Unordered, g => g.GroupName )
