Sorununuzu çözmenin yolu, WNetUseConnection adlı bir Win32 API kullanmaktır .
Sürücüyü eşlemek için DEĞİL, kimlik doğrulamalı UNC yoluna bağlanmak için bu işlevi kullanın .
Bu, aynı etki alanında olmasa bile ve farklı bir kullanıcı adı ve parolasına sahip olsa bile uzak bir makineye bağlanmanıza izin verir.
WNetUseConnection'ı kullandıktan sonra, dosyaya aynı etki alanındaymışsınız gibi bir UNC yolu üzerinden erişebileceksiniz. En iyi yol, muhtemelen yerleşik hisse senetleri aracılığıyladır.
Örnek: \\ bilgisayaradı \ c $ \ program files \ Folder \ file.txt
İşte WNetUseConnection kullanan bazı örnek C # kodu.
NetResource için, lpLocalName ve lpProvider için null değerini iletmeniz gerektiğini unutmayın. DwType, RESOURCETYPE_DISK olmalıdır. LpRemoteName \\ BilgisayarAdı olmalıdır.
