public static void SetCurrentDirectory(
	string path
)

Public Shared Sub SetCurrentDirectory ( 
	path As String
)

public:
static void SetCurrentDirectory(
	String^ path
)

static member SetCurrentDirectory : 
        path : string -> unit 

Parameters

path

Type: SystemString
The path to which the current working directory is set.

MSDN: Multithreaded applications and shared library code should not use the SetCurrentDirectory function and

should avoid using relative path names. The current directory state written by the SetCurrentDirectory function is stored as a global variable in each process,

therefore multithreaded applications cannot reliably use this value without possible data corruption from other threads that may also be reading or setting this value.

This limitation also applies to the GetCurrentDirectory and GetFullPathName functions. The exception being when the application is guaranteed to be running in a single thread,

for example parsing file names from the command line argument string in the main thread prior to creating any additional threads.

Using relative path names in multithreaded applications or shared library code can yield unpredictable results and is not supported.
