For .Net Framework 4.5 and above, you can use the Exception.HResult property: static

问题 I\'m using Python 2.6 on Linux. What is the fastest way: to determine which partition contains a given directory or file?

From the string \"/home/foo/bar/baz\" I would like to recover the pair (\"/dev/mapper/foo\", \"home/foo\") . and then, to get usage statistics of the given partition? For example, given /dev/mapper/foo I would like to obtain the size of the partition and the free space
