Açıklamalar

sınıfı, FileSystemInfo dosya ve dizin işleme için ortak olan yöntemler içerir. Bir FileSystemInfo nesne bir dosyayı veya dizini temsil edebilir, bu nedenle veya DirectoryInfo nesneleri için FileInfo temel görevi görür. Çok sayıda dosya ve dizini ayrıştırırken bu temel sınıfı kullanın.

Türetilmiş bir sınıf yalnızca türetilen sınıfın numaralandırmasından AllAccess iznine sahip olması durumunda öğesinden FileIOPermissionAccess devralabilirFileSystemInfo.

Yolu kabul eden üyelerde yol bir dosyaya veya yalnızca bir dizine başvurabilir. Belirtilen yol, bir sunucu ve paylaşım adı için göreli yola veya Evrensel Adlandırma Kuralı (UNC) yoluna da başvurabilir. Örneğin, aşağıdakilerin tümü kabul edilebilir yollardır:

• C# dilinde "c:\\MyDir\\MyFile.txt", Visual Basic'te "c:\MyDir\MyFile.txt".

• C# dilinde "c:\\MyDir" veya Visual Basic'te "c:\MyDir".

• C# dilinde "MyDir\\MySubdir" veya Visual Basic'te "MyDir\MySubDir".

• C# dilinde "\\\\MyServer\\MyShare" veya Visual Basic'te "\\MyServer\MyShare".
