Question

我有一个错误页面，其布局在大多数情况下都能正常工作，但是当控制器中出现错误并返回局部视图时，错误页面及其布局将放置在局部视图中。我想这是合乎逻辑的，但我希望将错误页面加载为整页。如何在不更改所有错误处理的情况下完成此操作。

的web.config：

<customErrors mode="On" defaultRedirect="~/Error">
  <error statusCode="500" redirect="~/SystemPages/ErrorPage" />
  <error statusCode="403" redirect="~/SystemPages/FileNotFound" />
  <error statusCode="404" redirect="~/SystemPages/FileNotFound" />
</customErrors>

的Global.asax：

Shared Sub RegisterGlobalFilters(ByVal filters As GlobalFilterCollection)
    filters.Add(New HandleErrorAttribute())
End Sub

BaseController：

Protected Overrides Sub OnException(ByVal filterContext As ExceptionContext)

    If filterContext Is Nothing Then Return

    If TypeOf (filterContext.Exception) Is FaultException Then
        Dim CodeName As String = 
        CType(filterContext.Exception, FaultException).Code.Name
        Dim Message As String = CType(filterContext.Exception, FaultException).Message
        TempData("ErrorMessage") = Message
    Else
        Logging.LogDebugData(HamtaDebugInformation(filterContext.RouteData))
        Logging.WriteExceptionLog(filterContext.Exception)
        TempData("ErrorMessage") = filterContext.Exception.Message
    End If

    Response.Redirect("/SystemPages/ErrorPage")

End Sub

SearchController：

   Function GetData() As ActionResult
   ...
   Return PartialView("_Tab", vmData)

的errorPage：

@Code
ViewData("Title") = "ErrorPage"
Layout = "~/Views/Shared/_Layout.vbhtml"
End Code

<div id="mainContent" class="oneColumn">
<div class="panel">
    <span class="panelTLC"></span>
    <span class="panelTRC"></span>
    <div id="inputPanel" class="panelContent">
        <div class="modul">
            <div class="modulHead">
                <span class="TLC"></span>
                <span class="TRC"></span>
            </div>
            <div class="modulContent">
                <span class="TLC"></span><span class="TRC"></span>
                <p>@ViewBag.ErrorMessage</p>
                <p>@TempData("ErrorMessage")</p>
                <span class="BLC"></span>
                <span class="BRC"></span>
            </div>
        </div>
    </div>
    <span class="panelBLC"></span><span class="panelBRC"></span>
</div>
</div>

你可以使用try catch块并在catch中返回一个View（）而不是PartialView（）。

Function GetData() As ActionResult
Try
...
Return PartialView("_Tab", vmData)
Catch ex as Exception
//Handle exception here ( send to error log, etc)
Return View("~/SystemPages/ErrorPage")
End Try

OR

的web.config：

<customErrors mode="On"/>

BaseController：

Protected Overrides Sub OnException(ByVal filterContext As ExceptionContext)

    If filterContext Is Nothing Then Return

    Dim Message As String

    If TypeOf (filterContext.Exception) Is FaultException Then
        Dim CodeName As String = 
        CType(filterContext.Exception, FaultException).Code.Name
        Message = CType(filterContext.Exception, FaultException).Message
    Else
        Logging.LogDebugData(HamtaDebugInformation(filterContext.RouteData))
        Logging.WriteExceptionLog(filterContext.Exception)
        Message = filterContext.Exception.Message
    End If

    Response.Redirect(String.Format("~/Error/HttpError/?message={1}", "HttpError", Message))

End Sub

ErrorController：

public class ErrorController : Controller
{
    // GET: /Error/HttpError
    public ActionResult HttpError(string message) {
       return View("ErrorTest", message);
}

这篇文章：ASP.NET MVC Custom Error Handling Application_Error Global.asax?

分别介绍了如何处理每种类型的错误。请记住，您正在使用basecontroller而不是global.asax文件处理异常。如果你能够改变你的异常处理，那将是更好的方法。
