c# - 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 than a specified lenght:

abc ..
abc ..
abc

Is there any simple C# code I can use for this?

Answer 1

Here is the logic wrapped up in an extension method:

public static string Truncate(this string value, int maxChars)
{
    return value.Length <= maxChars ? value : value.Substring(0, maxChars) + "...";
}

Usage:

var s = "abcdefg";

Console.WriteLine(s.Truncate(3));
