Remove readonly attribute from directory

Question

How can I programatically remove the readonly attribute from a directory in C#?

Answer 1

Here's a good link to examples of modifying file attributes using c#

http://www.csharp-examples.net/file-attributes/

based on their example, you can remove the Read Only attribute like this (I haven't tested this):

File.SetAttributes(filePath, File.GetAttributes(filePath) & ~FileAttributes.ReadOnly);

Answer 2

Setting Attributes to FileAttributes.Normal worked for me on both folders and files.

Answer 3

var di = new DirectoryInfo("SomeFolder");
di.Attributes &= ~FileAttributes.ReadOnly;

Answer 4

And the version with everything at once if something did not work

        this._path = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "My App Settings");

        if (!Directory.Exists(this._path))
        {
            Directory.CreateDirectory(this._path);

            DirectoryInfo directoryInfo = new DirectoryInfo(this._path);
            directoryInfo.Attributes &= ~FileAttributes.ReadOnly;

            FileSystemInfo[] info = directoryInfo.GetFileSystemInfos("*", SearchOption.AllDirectories);
            for (int i = 0; i < info.Length; i++)
            {
                info[i].Attributes = FileAttributes.Normal;
            }
        }

Answer 5

If you're attempting to remove the attribute of a file in the file system, create an instance of the System.IO.FileInfo class and set the property IsReadOnly to false.

        FileInfo file = new FileInfo("c:\\microsoft.text");
        file.IsReadOnly = false;

    public static void DeleteDirectory(string path)
    {
        var directory = new DirectoryInfo(path) 
        { Attributes =FileAttributes.Normal };
        foreach (var info in directory.GetFileSystemInfos("*", SearchOption.AllDirectories))
        {
            info.Attributes = FileAttributes.Normal;
        }
        directory.Delete(true);
    }
