.net的geteuid（）等价于什么？

Question

I would like to check programmatically what is the effective user who owns the process, from inside that process, under windows.

Might be winapi, but a .net solution is preferable.

There is an complicated system of which I do not have a perfect control, an .net app gets 'access denied' to some network filesystem path, and hence I would like to know which user should get the privileges to access this path, so I need a user that owns the process which tries to access it.

Answer 1

with Windows APIs:

GetUserNameEx function

in C#:

WindowsIdentity.GetCurrent().Name;

Answer 2

Although not .net, the following article from the Unix to Windows Porting Dictionary on:

uid_t getuid();
uid_t geteuid();

... is a good start to solving this problem.

From that article:

A Unix process maintains a distinction between the UID of the user that started the process (the real UID) and the UID of the user that the process is running as (the effective UID). Windows does not maintain this distinction. The value of a SID will be the equivalent of the Unix effective UID. Since the equivalent of the Unix real UID cannot be obtained using the SID is recommended for Windows when the real or effective UID is needed.
