SharePoint - 將網站部件從模板網站複製到新網站 - XML錯誤

Question

不確定從哪裏開始。我有代碼設置來創建一個新站點，然後從模板站點複製外觀，列表和Web部件。

它在作爲系統管理員登錄時工作得很好！

foreach (Microsoft.SharePoint.WebPartPages.WebPart webPartTemplate in webPartCollectionTemplate) 
{ 
    try 
    { 
MemoryStream memoryStream = new MemoryStream(); 
XmlTextWriter xmlWriter = new XmlTextWriter(memoryStream, Encoding.UTF8); 
webPartManagerTemplate.ExportWebPart(webPartTemplate, xmlWriter); 
xmlWriter.Flush(); 
memoryStream.Flush(); 
memoryStream.Position = 0; 

XmlTextReader xmlReader = new XmlTextReader(memoryStream); 

Microsoft.SharePoint.WebPartPages.ListViewWebPart listViewWebPartTemplate = null; 
Microsoft.SharePoint.WebPartPages.ListViewWebPart listViewWebPartTarget = null; 
Microsoft.SharePoint.WebPartPages.WebPart webPartTarget = null; 

bool webPartIsListViewWebPart = false; 

// If it throws an exception, the web part is not a ListViewWebPart 
try 
{ 
    listViewWebPartTemplate = (ListViewWebPart)webPartTemplate; 
    webPartIsListViewWebPart = true; 
} 
catch { } 

if (webPartIsListViewWebPart) 
{ 
    string errorMessage = ""; 
    listViewWebPartTarget = (Microsoft.SharePoint.WebPartPages.ListViewWebPart)webPartManagerTarget.ImportWebPart(xmlReader, out errorMessage); 

    if (errorMessage != null) 
    // log it 

    // Drop the brackets from the Guid and create a Guid object from the string. Then use it to find the list so we can get the title. 
    SPList listTemplate = webTemplate.Lists[new Guid(listViewWebPartTemplate.ListName.ToString().TrimStart('{').TrimEnd('}'))]; 
    SPList listTarget = webTarget.Lists[listTemplate.Title]; 

    listViewWebPartTarget.ListName = listTarget.ID.ToString("B").ToUpper(); 
    listViewWebPartTarget.WebId = webTarget.ID; 
    listViewWebPartTarget.TitleUrl = webPartTemplate.TitleUrl.ToString().Replace(siteTemplate.ServerRelativeUrl, siteTarget.ServerRelativeUrl); 
    listViewWebPartTarget.Title = webPartTemplate.Title; 
    listViewWebPartTarget.ZoneID = webPartTemplate.ZoneID; 

    webPartDictTarget.Add(listViewWebPartTarget.ZoneID + webPartTemplate.ZoneIndex.ToString(), listViewWebPartTarget); 
} 
else 
{ 
    string errorMessage = ""; 
    webPartTarget = (Microsoft.SharePoint.WebPartPages.WebPart)webPartManagerTarget.ImportWebPart(xmlReader, out errorMessage); 

    if (errorMessage != null) 
    // log it 

    webPartTarget.ChromeType = webPartTemplate.ChromeType; 
    webPartTarget.TitleUrl = webPartTemplate.TitleUrl.ToString().Replace(siteTemplate.ServerRelativeUrl, siteTarget.ServerRelativeUrl); 
    webPartTarget.Title = webPartTemplate.Title; 
    webPartTarget.ZoneID = webPartTemplate.ZoneID; 

    webPartDictTarget.Add(webPartTarget.ZoneID + webPartTemplate.ZoneIndex.ToString(), webPartTarget); 
} 
    } 
    catch (Exception ex) 
    { 
    } 
} 

// Acquire keys and sort them. 
List<string> list = new List<string>(webPartDictTarget.Keys); 
list.Sort(); 

// Loop through keys. 
int i = 0; 
foreach (var key in list) 
{ 
    try 
    { 
    Microsoft.SharePoint.WebPartPages.WebPart wpTmp = (Microsoft.SharePoint.WebPartPages.WebPart)webPartDictTarget[key]; 
    webPartManagerTarget.AddWebPart(wpTmp, wpTmp.ZoneID, i); 
    } 
    catch (Exception ex) 
    { 
    } 
    i++; 
} 

錯誤被扔到以下行：

webPartManagerTarget.AddWebPart(wpTmp, wpTmp.ZoneID, i); 

堆棧跟蹤如下{ 「時發生錯誤，產生XML文檔。」}：

在System.Xml.Serialization.XmlSerializer.Serialize（XmlWriter xmlWriter，Object o，XmlSerializerNamespaces命名空間，字符串 的encodingStyle，字符串ID）在 System.Xml.Serialization.XmlSerializer.Serialize（XmlWriter的XmlWriter的， 對象o）維持在 微軟 Microsoft.SharePoint.WebPartPages.WebPart.SerializeXml（XmlWriter的 作家，XmlSerializer的個XML，布爾shouldSerializeAll） .SharePoint.WebPartPages.WebPart.WriteXmlAsBytes（XmlSerializer的 個XML）在 Microsoft.SharePoint.WebPartPages.WebPart.WriteXmlGlobal（布爾 disableSafeControlsCheck）在 Microsoft.SharePoint.WebPartPages.BinaryWebPartSerializer.Serialize（PersonalizationScope 範圍）在 Microsoft.SharePoint程序.WebPartPages.BinaryWebPartSerializer.get_Links（） at Microsoft.SharePoint.WebPartPages.SPWebPartManager.AddWebPartToStore（Web部件 web部件，的Int32 viewId，字符串viewGuid）在 Microsoft.SharePoint.WebPartPages.SPWebPartManager.AddWebPartInternal（SPSupersetWebPart 超集，布爾throwIfLocked）在 Microsoft.SharePoint.WebPartPages.SPLimitedWebPartManager。 AddWebPartInternal（Web部件 web部件，字符串了zoneid，的Int32 ZONEINDEX，布爾throwIfLocked）在 Microsoft.SharePoint.WebPartPages.SPLimitedWebPartManager.AddWebPart（Web部件 web部件，字符串了zoneid，的Int32 ZONEINDEX）在 admSitePanelSolution.admSiteCreateCollection。 <> C_ DisplayClasse.b _c（）

任何人都可以提供一些幫助，爲什麼發生這種情況時沒有以系統管理員身份登錄。整個模塊也在提升的權限內運行，並且SPSite和SPWeb也在高架模塊內實例化。此代碼是摘錄。

UPDATE

如果我讓用戶基礎的網站集的網站集所有者，那麼上面的代碼運行正常。那麼上面代碼中的內容會重置上下文，或者需要引用基本網站集。謝謝。

Answer 1

而且我的同事猛撲過來拯救一天！在SP開發中，有一個衆所周知的'hack'，當權限變得怪異和愚蠢時，這種'hack'被大量使用。它是無效的HttpContext。我在線和循環中試過這個問題，它給了我一個問題，但它似乎在導入期間必須在代碼中放置得高得多。

這是新的修復程序。

HttpContext currentContext = HttpContext.Current; 
HttpContext.Current = null; 
listViewWebPartTarget = (Microsoft.SharePoint.WebPartPages.ListViewWebPart)webPartManagerTarget.ImportWebPart(xmlReader, out errorMessage); 
HttpContext.Current = currentContext; 

此代碼現在適用於將webparts從一個apsx頁面複製到另一個頁面。希望它能幫助別人。
