How to read and modify NTFS Alternate Data Streams using .NET [closed]

by

Here is a version for C#

using System.Runtime.InteropServices;

class Program
{
    static void Main(string[] args)
    {
        var mainStream = NativeMethods.CreateFileW(
            "testfile",
            NativeConstants.GENERIC_WRITE,
            NativeConstants.FILE_SHARE_WRITE,
            IntPtr.Zero,
            NativeConstants.OPEN_ALWAYS,
            0,
            IntPtr.Zero);

        var stream = NativeMethods.CreateFileW(
            "testfile:stream",
            NativeConstants.GENERIC_WRITE,
            NativeConstants.FILE_SHARE_WRITE,
            IntPtr.Zero,
            NativeConstants.OPEN_ALWAYS,
            0,
            IntPtr.Zero);
    }
}

public partial class NativeMethods
{

    /// Return Type: HANDLE->void*
    ///lpFileName: LPCWSTR->WCHAR*
    ///dwDesiredAccess: DWORD->unsigned int
    ///dwShareMode: DWORD->unsigned int
    ///lpSecurityAttributes: LPSECURITY_ATTRIBUTES->_SECURITY_ATTRIBUTES*
    ///dwCreationDisposition: DWORD->unsigned int
    ///dwFlagsAndAttributes: DWORD->unsigned int
    ///hTemplateFile: HANDLE->void*
    [DllImportAttribute("kernel32.dll", EntryPoint = "CreateFileW")]
    public static extern System.IntPtr CreateFileW(
        [InAttribute()] [MarshalAsAttribute(UnmanagedType.LPWStr)] string lpFileName, 
        uint dwDesiredAccess, 
        uint dwShareMode, 
        [InAttribute()] System.IntPtr lpSecurityAttributes, 
        uint dwCreationDisposition, 
        uint dwFlagsAndAttributes, 
        [InAttribute()] System.IntPtr hTemplateFile
    );

}


public partial class NativeConstants
{

    /// GENERIC_WRITE -> (0x40000000L)
    public const int GENERIC_WRITE = 1073741824;

    /// FILE_SHARE_DELETE -> 0x00000004
    public const int FILE_SHARE_DELETE = 4;

    /// FILE_SHARE_WRITE -> 0x00000002
    public const int FILE_SHARE_WRITE = 2;

    /// FILE_SHARE_READ -> 0x00000001
    public const int FILE_SHARE_READ = 1;

    /// OPEN_ALWAYS -> 4
    public const int OPEN_ALWAYS = 4;
}
