Hi,

In my application I am moving files from one folder to another

When copied to target folder, I am deleting files from source folder

C#

filepath= Path.GetExtension(source + "\\" + fi.Name);
if (filepath == ".csv" || filepath == ".xls" || filepath == ".xlsx")
{
    if (!File.Exists(target + "\\" + fi.Name))
   {
                                
         fi.CopyTo(Path.Combine(target.ToString(), fi.Name), true);
         fi.Delete();
   }
}

When I do so, I am getting an error says 'Access denied to the file'. And then I manually removed read-only property. I want to know how it can be done through code.

Please help.

Try this:

C#

FileInfo fi = new FileInfo(path);
fi.IsReadOnly = false;
fi.Refresh();

Do something like the following to recursively clear readonly (and archive, etc.) for all directories and files within a specified parent directory.

C#

private void ClearReadOnly(DirectoryInfo parentDirectory)
{
    if(parentDirectory != null)
    {
        parentDirectory.Attributes = FileAttributes.Normal;
        foreach (FileInfo fi in parentDirectory.GetFiles())
        {
            fi.Attributes = FileAttributes.Normal;
        }
        foreach (DirectoryInfo di in parentDirectory.GetDirectories())
        {
            ClearReadOnly(di);
        }
    }
}

You can therefore call this like so:

C#

public void Main()
{
    DirectoryInfo parentDirectoryInfo = new DirectoryInfo(@"c:\test");
    ClearReadOnly(parentDirectoryInfo);
}
