How can I truncate my strings with a “…” if they are too long?

Question

Hope somebody has a good idea. I have strings like this:

abcdefg
abcde
abc

What I need is for them to be trucated to show like this if more

Answer 1

Code behind:

string shorten(sting s)
{
    //string s = abcdefg;
    int tooLongInt = 3;

    if (s.Length > tooLongInt)
        return s.Substring(0, tooLongInt) + "..";

    return s;
}

Markup:

<%= shorten(YOUR_STRING_HERE) %>
