I using C# .NET , vs 2008 , .net 3.5

For me, is difficult, but I need sample code in C# for this:

1. How get the error code of IOException "The process cannot access the file 'XYZ' because it is being used by another process."

For example, in my issue. 

I try delete file, and I get "The process cannot access the file 'XYZ' because it is being used by another process." Exception.

```
try
{
    File.Delete(infoFichero.Ruta);
}
catch (IOException ex)
{
    // ex.Message == "The process cannot access the file 'XYZ' because it is being used by another process."
}

```

But if .NET is Spanish, I get "El proceso no puede obtener acceso al archivo '00000004.PDF' porque está siendo utilizado en otro proceso" message. 

```
System.IO.IOException: El proceso no puede obtener acceso al archivo '00000004.PDF' porque está siendo utilizado en otro proceso.
   en System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
   en System.IO.FileInfo.Delete()

```

I need a ERROR CODE for that Exception. In Trace, I have seen System.IO.\_\_Error.WinIOError(Int32 errorCode, String maybeFullPath)

How get the error code of IOException "The process cannot access the file 'XYZ' because it is being used by another process."
