+I noticed that file URI must not disregard fragment identifier '#'. I
|
|
+retried on MS.NET and noticed that '#' is regarded as file name
|
|
+character only when constructed by absolute file path. My patch was
|
|
+wrong for pure file: scheme.
|
|
+
|
|
+As a quick summary, you can only use LocalPath directly. You cannot
|
|
+use AbsoluteUri; it is escaped.
|
|
+
|
|
+I wrote an example code:
|
|
+
|
|
+using System;
|
|
+
|
|
+public class Test
|
|
+{
|
|
+ public static void Main ()
|
|
+ {
|
|
+ Uri uri;
|
|
+
|
|
+ uri = new Uri ("<A HREF="file:///c:/cygwin/home/ginga/c#books"">file:///c:/cygwin/home/ginga/c#books"</A>);
|
|
+ DumpUri (uri);
|
|
+ uri = new Uri ("c:/cygwin/home/ginga/c#books");
|
|
+ DumpUri (uri);
|
|
+ uri = new Uri (new Uri
|
|
+("c:/cygwin/home/ginga/c#books"), "f#books");
|
|
+ DumpUri (uri);
|
|
+ }
|
|
+
|
|
+ public static void DumpUri (Uri uri)
|
|
+ {
|
|
+ Console.WriteLine ("localpath = [{0}]", uri.LocalPath);
|
|
+ Console.WriteLine ("abspath = [{0}]", uri.AbsolutePath);
|
|
+ }
|
|
+}
|
|
+
|
|
+The results were:
|
|
+
|
|
+./opaque.exe
|
|
+localpath = [c:\cygwin\home\ginga\c]
|
|
+abspath = [c:/cygwin/home/ginga/c]
|
|
+localpath = [c:\cygwin\home\ginga\c#books]
|
|
+abspath = [c:/cygwin/home/ginga/c%23books]
|
|
+localpath = [c:\cygwin\home\ginga\f]
|
|
+abspath = [c:/cygwin/home/ginga/f]
|
|
+
|
|
+The experiment above shows that LocalPath preserves '#', but
|
|
+AbsoluteUri does not preserve '#' and escapes it into "%23". I think
|
|
+we had better make Uri class to match with this behavior.
|
|
+
|
|
+Interestingly, on the third case, "f#books" is not recognized as a
|
|
+valid file path, but is regarded just as a fragment identifier. That
|
|
+means, we cannot create such file path from relative URI constructor.
|
|
+
|
|
+Note that we still have another bug with related to Unix file path:
|
|
+#58301.
|
|
+
|
|
+The fix for above is now checked in cvs.
