Answer 1

If you want do insert ellipsis dependent on the length of the path string, then use this code:

TextRenderer.MeasureText(path, Font, 
    new System.Drawing.Size(Width, 0),
    TextFormatFlags.PathEllipsis | TextFormatFlags.ModifyString);

It will modify path in-place.

EDIT: Be careful with this method. It breaks the rule, saying that strings in .NET are immutable. In fact, the first parameter of the MeasureText method is not a ref parameter, which means that no new string can be returned. Instead, the existing string is altered. It would be careful to work on a copy created with

string temp = String.Copy(path);
