问题
I have a long path I'd like to shorten for displaying on a form using the ellipsis character(s?).
I know there is the PathCompactPathEx Win32 API call, but I know there is a built-in .NET equivalent. I have used it previously, but cannot find it any more. Any hints, please?
回答1:
Your own link has
Alternative Managed API:
System.Windows.Forms.TextRenderer.MeasureText(String, Font, Size, TextFormatFlags.ModifyString | TextFormatFlags.PathEllipsis);
at the bottom. Is that what you are looking for?
回答2:
Using the ModifyString flag in versions of .Net since (at least) version 3.5 exposes an ugly and potentially dangerous bug discussed here.
Hans Passant found the correct way to do this here.
