Question

我在我的MVC应用程序中收到以下错误，我的所有调试似乎都可以识别它的来源。我已对我在该特定页面中所做的所有更改进行了撤消操作，但仍然出现此错误。但是，我在页面中使用了相当多的隐藏字段。可能导致此错误，如果是这样，我该如何解决？

发布以下堆栈跟踪中的代码：

的InnerException： System.NullReferenceException Message =“对象引用未设置为一个对象的实例。“ Source =“App_Web_lhjnw8uq”StackTrace：在 ASP.views_paymentapplications_paymentapplicationform_ascx._Render_control1（HtmlTextWriter的 _：w，Control parameterContainer）在c：\ ProjectsVisualStudio \ Projects.NET中 3.5 \镑\ ExceptionManager \ ExceptionManager \程序\ ExceptionManager.Web \查看\ PaymentApplications \ PaymentApplicationForm.ascx：行 98

使用我的通灵调试能力，我猜测：

您正在向RenderPartial发送一个'null'对象，并且它无法呈现部分对象。因此，检查setter是否要发送给RenderPartial，并查看它是否为null。
