C# set File Attributes [change file attribute to read only]

Set File Attributes: While working on a c# console application, I have a requirement to make all the files in read-only mode. In short, I need to change the file attribute and make them all read-only to end user. In C# with File.SetAttributes() we can easily set the attribute of any given file. Before writing any code first, we need to import System.IO namespace into our application. In C# we handle files with System.IO, it allows us to read/write any given file. We can also manipulate directories on the file system with System.IO.

Here in this article will learn how to set file attributes in C#. You can also check my previous article how to remove the read-only attribute from the file in c#.

File.SetAttributes(): This method is used to sets the specified FileAttributes to the given file.


public static void SetAttributes(
string path,
FileAttributes fileAttributes

path: the path of the file.
fileAttributes: this parameter is used to set attribute/ property of the file.

Below we have listed the fileAttributes member, which we can set to the file or directory.

C# Code:
Here is the bellow written code we set the read-only attribute to the given file.

using System;
using System.IO;

namespace CONSOLE_TUT
    class Program
        static void Main(string[] args)
            string filePath = @"D:\DummyTextFile.txt";
            File.SetAttributes(filePath, FileAttributes.ReadOnly);

            Console.WriteLine("The {0} file is now readonly.", filePath);

List of fileAttributes members:

  • Archive: The file is a candidate for backup or removal.
  • Compressed: The file is compressed.
  • Device: Reserved for future use.
  • Directory: The file is a directory.
  • Encrypted: The file or directory is encrypted. For a file, this means that all data in the file is encrypted. For a directory, this means that encryption is the default for newly created files and directories.
  • Hidden: The file is hidden and thus is not included in an ordinary directory listing.
  • IntegrityStream: The file or directory includes data integrity support. When this value is applied to a file, all data streams in the file have integrity support. When this value is applied to a directory, all new files and subdirectories within that directory, by default, include integrity support.
  • Normal: The file is a standard file that has no special attributes. This attribute is valid only if it is used alone.
  • Offline: The file is offline. The data of the file is not immediately available.
  • ReadOnly: The file is read-only.
  • SparseFile: The file is a sparse file. Sparse files are typically large files whose data consists of mostly zeros.
  • System: The file is a system file. That is, the file is part of the operating system or is used exclusively by the operating system.
  • Temporary: The file is temporary. A temporary file contains data that is needed while an application is executing but is not needed after the application is finished.
