List all ReadOnly files in a directory using C# (.NET)

C# Get Read Only Files

The following code will retrieve the read-only files using LINQ and C#

private static void GetFilesFromDirectory(string DirPath)

{

try

{

DirectoryInfo Dir = new DirectoryInfo(DirPath);

FileInfo[] FileList = Dir.GetFiles("*.*", SearchOption.TopDirectoryOnly );

var query = from FI in FileList

where FI.IsReadOnly == true

select FI.FullName + " " + FI.LastWriteTime;

foreach (string s1 in query )

{

Console.WriteLine(s1);

}

}

catch (Exception ex)

{

Console.WriteLine(ex.Message );

}

}

The above can (and mostly is) done by the following way

FileInfo[] FileList = Dir.GetFiles("*.*", SearchOption.TopDirectoryOnly );

foreach (FileInfo F1 in FileList)

{

if (F1.IsReadOnly == true)

{

Console.WriteLine(F1.FullName );

}

}
