Question

我正在为SharePoint Foundation 2010开发asp.net mvc应用程序.asp.net应用程序托管在一台计算机上，SharePoint Foundation 2010托管在另一台计算机上。我在SharePoint环境的ISAPI文件夹中部署了一个自定义wcf服务。此自定义wcf服务以编程方式创建内容数据库。 asp.net应用程序使用此自定义wcf服务。我正在使用这种方法，因为我的方案类似于链接 - http://blog.sharedove.com/adisjugo/index.php/2012/07/31/creating-site-collections-in-specific-content-database/。实现上述场景我遇到了错误 - http://social.technet.microsoft.com/Forums/en-US/sharepointdevelopmentprevious/thread/f10d009b-13c4-4942-86b4-2ab8c4f5994d。我用http://beyondweblogs.com/sharepoint-2010-sppersistedobject-access-denied/解决了这个错误。现在我收到错误 - System.InvalidOperationException：由于对象的当前状态，操作无效。

System.InvalidOperationException: Operation is not valid due to the current state of the object.

此错误在上面的链接bolg.sharedove.com中有所描述。我想我需要按照bolg.sharedove.com

中的描述设置以下代码

var storeContext = HttpContext.Current; 
HttpContext.Current = null; 
// do your code 
HttpContext.Current = storeContext;

我thnik我无法在wcf服务中设置上述代码。我试图在asp.net应用程序中设置它，但发生了同样的错误。请问anuone请告诉我应该在哪里设置此代码？如果有人有不同的解决方案，请分享。

Answer 1

我只是在wcf服务应用程序中添加了对System.Web.dll的引用。现在我可以在wcf中使用HttpContext。我在wcf

中设置了以下代码

var storeContext = HttpContext.Current; 
HttpContext.Current = null; 
// do your code 
HttpContext.Current = storeContext;

现在wcf中的所有代码都运行正常。我现在能够以编程方式创建内容数据库和网站集。

System.InvalidOperationException：由于对象的当前状态，操作无效。
