xmltextwriter文件锁IIS 6

Question

我正在使用它，但在IIS 6中运行的MVC .NET 4.0网站创建文件后，我仍无法删除该文件。

    using (XmlTextWriter writer = new XmlTextWriter(myfolder + filename, null))
            {
                using (XmlReader reader = xd.CreateReader())
                {
                    XslCompiledTransform xmlTransform = new XslCompiledTransform();
                    writer.Settings.CloseOutput = true;
                    xmlTransform.OutputSettings.CloseOutput = true;
                    reader.Settings.CloseInput = true;
                    xmlTransform.Load((System.Web.HttpContext.Current.Server.MapPath("~/myxslt.xslt")));
                    xmlTransform.Transform(reader, writer);
                }
            }
