    response.End();
}

.NET 4.0¶

    int size = bytes.GetUpperBound(0) + 1;

    char[] c = new char[size];

    bytes.CopyTo(c, 0);

    //- Write PDF Contents to HTTP Response -----------------------------------------------
    response.Buffer = true;

    response.AddHeader("content-disposition", "attachment; filename=" + rdlcFileName + "." 
        + fileNameExtension);

    response.Flush();
    response.End();
