Assembly: mscorlib (in mscorlib.dll)
public: property FileAttributes Attributes { FileAttributes get(); void set(FileAttributes value); }
| Exception | Condition |
|---|---|
| FileNotFoundException | The specified file does not exist. |
| DirectoryNotFoundException | The specified path is invalid; for example, it is on an unmapped drive. |
| SecurityException | The caller does not have the required permission. |

The value of the Attributes property is pre-cached if the current instance of the FileSystemInfo object was returned from any of the following DirectoryInfo methods:
To get the latest value, call the Refresh method.
The value of this property is a combination of the archive, compressed, directory, hidden, offline, read-only, system, and temporary file attribute flags.
When you set this value, use the bitwise OR operator (| in C# or Or in Visual Basic) to apply more than one value. To retain any existing values in the Attributes property, include the value of the Attributes property in your assignment. For example:
exampleFile.Attributes = exampleFile.Attributes | FileAttributes.ReadOnly;
The following example demonstrates the Attributes property. This code example is part of a larger example provided for the FileSystemInfo class.
static void DisplayFileSystemInfoAttributes(FileSystemInfo^ fsi) { // Assume that this entry is a file. String^ entryType = "File"; // Determine if entry is really a directory if ((fsi->Attributes & FileAttributes::Directory) == FileAttributes::Directory) { entryType = "Directory"; } // Show this entry's type, name, and creation date. Console::WriteLine("{0} entry {1} was created on {2:D}", entryType, fsi->FullName, fsi->CreationTime); }
