我有以下功能:PathRelativePathTo正在改變的unicode charactrs以ASCII
public static string GetRelativePath(string fromPath, string toPath)
{
// we also tried the Uri solution but that does not return .. when you need to traverse
// one up only
// uri1 = "bla\foo"
// uri2 = "bla\bar"
// uri1.MakeRelaitveto(uri2) != "..\bar"
var path = new StringBuilder(260); // MAX_PATH
if (PathRelativePathTo(
path,
fromPath.Replace('/', '\\'),
FILE_ATTRIBUTE_DIRECTORY,
toPath.Replace('/', '\\'),
FILE_ATTRIBUTE_DIRECTORY) == 0)
{
return toPath;
}
return path.ToString().Replace('\\', Path.DirectorySeparatorChar);
}
[DllImport("shlwapi.dll", SetLastError = true)]
private static extern int PathRelativePathTo(
StringBuilder pszPath, string pszFrom, int dwAttrFrom, string pszTo, int dwAttrTo);
}
我與下面的測試用例撥打:
GetPathRelativeTo("C:\\somεpath", "C:\\anothεrpath").Shouldbe("..\\anothεrpath")
而是它返回..\\anotherpath
。請注意,ε
已被替換爲e
。
我嘗試過使用PathRelativePathToW
,但是它的工作更少(其他測試用例失敗)。
有誰知道是怎麼回事,我怎麼能防止更換炭的?
