Solution.

Some times we may have to make file readonly programatically.

To make readonly...

foreach (string fileName in System.IO.Directory.GetFiles(path))
{
    System.IO.FileInfo fileInfo = new System.IO.FileInfo(fileName);
    fileInfo.Attributes |= System.IO.FileAttributes.ReadOnly;
    // or
    fileInfo.IsReadOnly = true;
}

To change attribute readily only false

foreach (string fileName in System.IO.Directory.GetFiles(configFilePath))
{
    System.IO.FileInfo fileInfo = new System.IO.FileInfo(fileName);
    if(fileInfo.IsReadOnly == true)
        fileInfo.IsReadOnly = false;
}
