Question

I am trying to open a file, but I received:

The process cannot access the file because it is being used by another process. The File is an XML-Document. Can anyone help?

  string activeDirectory = @"X:\SubGraph\";
  string[] files = Directory.GetFiles(activeDirectory);
  foreach (string fileName in files){
  FileStream file = new FileStream(fileName, FileMode.Open, FileAccess.Read);

After using a file, you must to close it, I think:

foreach (string fileName in files)
{
    FileStream file = new FileStream(fileName, FileMode.Open, FileAccess.Read);
    //your code 
    file.Close();
}
