SPDisposeCheck 报告 SiteProvisioning.RestoreDataViewOutZone 方法上的错误

Question

我在 SharePoint 程序集上运行了 SPDisposeCheck 工具，但它在 SiteDefinitionAssembly 上报告了三个错误，该 SiteDefinitionAssembly 也具有网站配置处理程序。据我了解，此代码是由项目模板本身生成的，我们不应该更改它。我得到的错误是

这是生成的代码

private void RestoreDataViewInZone(SPWeb web, string filePath)
        {
            if (!File.Exists(filePath) || web == null)
            {
                return;
            }

            XmlDocument doc = new XmlDocument();
            try
            {
                doc.Load(filePath);
            }
            catch (XmlException)
            {
                return;
            }

            XmlNodeList xFixupFiles = doc.DocumentElement.SelectNodes("FixupFiles/FixupFile[@DataViewInZone=\"TRUE\"]");
            foreach (XmlNode xFixupFile in xFixupFiles)
            {
                XmlAttribute xRelativePath = xFixupFile.Attributes["RelativePath"];
                if (xRelativePath == null)
                {
                    continue;
                }
                string relativePath = xRelativePath.Value;

                SPFile file = web.GetFile(relativePath);
                if (file == null)
                {
                    continue;
                }

                SPLimitedWebPartManager manager = file.GetLimitedWebPartManager(System.Web.UI.WebControls.WebParts.PersonalizationScope.Shared);
                SPLimitedWebPartCollection pageWebParts = manager.WebParts;
                if (pageWebParts == null)
                {
                    continue;
                }

                foreach (System.Web.UI.WebControls.WebParts.WebPart webPart in pageWebParts)
                {
                    DataFormWebPart dataForm = webPart as DataFormWebPart;
                    if (dataForm == null)
                    {
                        continue;
                    }

                    this.SubstituteGuidInZone(web, manager, dataForm, filePath);
                }
            }
        }

我确实知道 SPWeb 对象未在函数中释放，但我不确定是否应该释放它。

我需要担心这个错误吗？

谢谢

终于弄清楚

GetLimitedWebPartManager 方法返回应处置的 SPWeb 对象。
