FileAttributes of the current FileSystemInfo.

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);
