问题 I have a repositories implemented with unitOfWork pattern and share a context. i have a service layer on top of these repositories. which has multiple services. When ever i instantiate a service class - unitOfWork instance is created. But many times these services methods call each other and sometimes operate on common session objects. Which causes a problem of the same entity being tracked by multiple contexts or more specifically - An entity object cannot be referenced by multiple instances

问题 I have the following code: public ActionResult Index() { AdminPreRegUploadModel model = new AdminPreRegUploadModel() { SuccessCount = successAddedCount, FailureCount = failedAddedCount, AddedFailure = addedFailure, AddedSuccess = addedSuccess }; return RedirectToAction("PreRegExceUpload", new { model = model }); } public ActionResult PreRegExceUpload(AdminPreRegUploadModel model) { return View(model); } but model is null when I breakpoint on PreRegExcelUpload.

问题 I am using ASP.NET MVC 3 with .NET 4.0. I have a model on which one of the properties requires that HTML content be allowed. I have placed the AllowHtml attribute on my model property which allows HTML on that property. That works by itself. I am also using the Uploadify flash uploader on other parts of my website. Due to problems with flash and sessions, I'm using some code similar to the code in a swfupload example to allow my file upload access to session data. Basically I'm accessing the

问题 I configured log4net with a smtpAppender (gmail). The weird issue is that the smtpAppender is not working when I deploy the application on IIS 7.5. I tried to test the connection with the gmail smtp using telnet command. So I can check if anything is blocked but the test worked fine.

I've traced the reason why

问题 I am building a solution with Sitecore 7 and ASP.NET-MVC 3 and trying to use a custom model class as described in this blog post by john west. I have seen several other questions here on SO reporting a similar error with ASP.NET-MVC (without Sitecore), usually related to passing the wrong type of object in controller code, or there being a configuration error with the \Views\web.config file, but neither seem to be the issue here. 回答1: this issue is caused when you create a view rendering
