Hi

Does anybody know how to create and show a reparse point in c#? I'm able to determine if a folder is a reparse point or not by looking at the file attributes, but how do I get the reparse info

Hello,

you should use the DeviceIoControl function (using interop)

[DllImport("kernel32.dll")]
public static extern bool DeviceIoControl(IntPtr hDevice, uint
dwIoControlCode, byte [] lpInBuffer, uint nInBufferSize, [Out] byte []
lpOutBuffer, uint nOutBufferSize, IntPtr lpBytesReturned, IntPtr
lpOverlapped);

Thanks for your reply

I have been looking at this solution, bu I havn't gotten it to work. My problem was that it needed a struct which I wasn't able to convert to c#. Do you know how to do it

Hello,

I'd try the following :

public struct OVERLAPPED
{
IntPtr Internal;
IntPtr InternalHigh;
int Offset;
int OffsetHigh;
IntPtr hEvent;
};

with

[DllImport("kernel32.dll")]
public static extern bool DeviceIoControl(IntPtr hDevice, uint
dwIoControlCode,
byte [] lpInBuffer, uint nInBufferSize, [Out] byte [] lpOutBuffer,
uint nOutBufferSize, IntPtr lpBytesReturned, ref OVERLAPPED lpOverlapped);
