Question

I have a List<string> myList like shown below:

widget1
widget2
widget3
widget4

I’d like to show this on my web page like the following

widget1 | widget3 | widget4

Let’s just say if the string is “widget2” leave it out.

is there a way to do this with a linq statement?

<div>
    <% myList.ForEach(x => Response.Write(Html.ActionLink(x.Name,"ActionMethod"))); %>
</div>

i know i’m asking too much but i thought i’d try.

Answer 1

You could do something like this:

<%= String.Join(" | ", myList
    .Where(x => x.Name != "Widget 2")
    .Select(x => Html.ActionLink(x,"ActionMethod").ToString()) %>

Then just modify the where statement to fit your needs. I guess it is a matter of preference, but I dislike to use Response.Write in views, and I try to avoid the ForEach() method because it doesn’t work on plain IEnumerables.
