Я думаю, что .NET Framework не предоставляет информацию, необходимую для сравнения двух каталогов ...
Вы должны принять неуправляемый подход. Вот как я это сделал:
class Program
{
struct BY_HANDLE_FILE_INFORMATION
{
public uint FileAttributes;
public System.Runtime.InteropServices.ComTypes.FILETIME CreationTime;
public System.Runtime.InteropServices.ComTypes.FILETIME LastAccessTime;
public System.Runtime.InteropServices.ComTypes.FILETIME LastWriteTime;
public uint VolumeSerialNumber;
public uint FileSizeHigh;
public uint FileSizeLow;
public uint NumberOfLinks;
public uint FileIndexHigh;
public uint FileIndexLow;
}
//
// CreateFile constants
//
const uint FILE_SHARE_READ = 0x00000001;
const uint FILE_SHARE_WRITE = 0x00000002;
const uint FILE_SHARE_DELETE = 0x00000004;
const uint OPEN_EXISTING = 3;
const uint GENERIC_READ = (0x80000000);
const uint GENERIC_WRITE = (0x40000000);
const uint FILE_FLAG_NO_BUFFERING = 0x20000000;
const uint FILE_READ_ATTRIBUTES = (0x0080);
const uint FILE_WRITE_ATTRIBUTES = 0x0100;
const uint ERROR_INSUFFICIENT_BUFFER = 122;
const uint FILE_FLAG_BACKUP_SEMANTICS = 0x02000000;
[DllImport("kernel32.dll", SetLastError = true)]
static extern IntPtr CreateFile(
string lpFileName,
uint dwDesiredAccess,
uint dwShareMode,
IntPtr lpSecurityAttributes,
uint dwCreationDisposition,
uint dwFlagsAndAttributes,
IntPtr hTemplateFile);
[DllImport("kernel32.dll", SetLastError = true)]
static extern bool GetFileInformationByHandle(IntPtr hFile, out BY_HANDLE_FILE_INFORMATION lpFileInformation);
static void Main(string[] args)
{
string dir1 = @"C:\MyTestDir";
string dir2 = @"\\myMachine\MyTestDir";
Console.WriteLine(CompareDirectories(dir1, dir2));
}
static bool CompareDirectories(string dir1, string dir2)
{
BY_HANDLE_FILE_INFORMATION fileInfo1, fileInfo2;
IntPtr ptr1 = CreateFile(dir1, GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, IntPtr.Zero, OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, IntPtr.Zero);
if ((int)ptr1 == -1)
{
System.ComponentModel.Win32Exception t = new System.ComponentModel.Win32Exception(Marshal.GetLastWin32Error());
Console.WriteLine(dir1 + ": " + t.Message);
return false;
}
IntPtr ptr2 = CreateFile(dir2, GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, IntPtr.Zero, OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, IntPtr.Zero);
if ((int)ptr2 == -1)
{
System.ComponentModel.Win32Exception t = new System.ComponentModel.Win32Exception(Marshal.GetLastWin32Error());
Console.WriteLine(dir2 + ": " + t.Message);
return false;
}
GetFileInformationByHandle(ptr1, out fileInfo1);
GetFileInformationByHandle(ptr2, out fileInfo2);
return ((fileInfo1.FileIndexHigh == fileInfo2.FileIndexHigh) &&
(fileInfo1.FileIndexLow == fileInfo2.FileIndexLow));
}
}
Это работает! Надеюсь, это поможет.
Приветствие.
