Long path with ellipsis in the middle [duplicate]

Answer 1

Here is what I use. It very nicely create ellipsis in the middle of a path and it also allows you to speciy any length or delimiter.

Note this is an extension method so you can use it like so `"c:\path\file.foo".EllipsisString()

I doubt you need the while loop, in fact you probably don't, I was just too busy to test properly

    public static string EllipsisString(this string rawString, int maxLength = 30, char delimiter = '\\')
    {
        maxLength -= 3; //account for delimiter spacing

        if (rawString.Length <= maxLength)
        {
            return rawString;
        }

        string final = rawString;
        List parts;

        int loops = 0;
        while (loops++ < 100)
        {
            parts = rawString.Split(delimiter).ToList();
            parts.RemoveRange(parts.Count - 1 - loops, loops);
            if (parts.Count == 1)
            {
                return parts.Last();
            }

            parts.Insert(parts.Count - 1, "...");
            final = string.Join(delimiter.ToString(), parts);
            if (final.Length < maxLength)
            {
                return final;
            }
        }

        return rawString.Split(delimiter).ToList().Last();
    }
