Answer 1

堆栈跟踪包含答案:

使用自定义TextWriter时,OutputStream不可用.在System.Web.HttpResponse.get_OutputStream()中的AjaxControlToolkit.ToolkitScriptManager.OutputCombinedScriptFile(HttpContext context)中的C:\ AjaxBuild\Ajax\Server\AjaxControlToolkit\ToolkitScriptManager\ToolkitScriptManager.cs:第286行,位于AjaxControlToolkit.ToolkitScriptManager.OnInit(EventArgs e)在C:\ AjaxBuild\Ajax\Server\AjaxControlToolkit\ToolkitScriptManager\ToolkitScriptManager.cs:系统中的System.Web.UI.Control.InitRecursive(Control namingContainer)的System.Web.UI.Control.InitRecursive(Control namingContainer)中的第246行System.Web.UI.Page.ProcessRequestMain的System.Web.UI.Control.InitRecursive(Control namingContainer)中的.Web.UI.Control.InitRecursive(Control namingContainer)(Boolean includeStagesBeforeAsyncPoint,

您正在使用AjaxControlToolkit,它是服务器控件的集合.ASP.NET MVC不支持服务器控件.您可能希望调用AjaxControlToolkit的Javascript API而不是使用服务器控件,因为这应该以符合MVC的方式为您提供所需的行为.

Answer 2

您的MVC视图代码可能包含语法错误.您可能在错误日志中看到错误消息,但它不会阻止站点运行,因为View代码的编译方式与标准类的编译方式不同.

因此,请检查错误日志中是否有任何语法错误消息
