如何实现在asp.net的MVC

自定义错误页我想实现一个自定义错误页，显示我自己的错误消息，而不是显示默认的错误消息。如何实现在asp.net的MVC

，所以我已在web.config文件中的一些变化。这里是我的web.config文件

我的错误页面存储在文件夹视图和该共享文件夹。请帮我显示自定义错误页。

我收到称为运行时错误“而处理您的请求时发生异常。另外，在执行自定义错误页的第一个异常又发生了异常。该请求已被终止。” –

使用Visual Studio调试模式下，交未处理的异常，你已经到达那里。也'的defaultRedirect =“Error.cshtml”'是不调用CSHTML文件一个正确的事，需要定义误差控制器然后使用虚拟路径调用定制错误动作方法（例如'的defaultRedirect =“〜/错误”'）。 –

谢谢。我通过添加名为ErrorController的新控制器并在其中保存了一个方法来完成此操作。该方法调用我的customErrror页面。现在它工作的404错误。 –

从给定web.config文件，似乎这些线触发第二异常而返回定义错误页：

<customErrors mode="On" defaultRedirect="Error.cshtml" > 
    <error statusCode="404" redirect="~/Error.cshtml" /> 
</customErrors>

由于defaultRedirect属性只接受一个HTML文件或虚拟/相对路径的控制器动作任一绝对路径到CSHTML文件的方法，直接绝对路径是不合适的，由于它里面剃刀码应使用的操作方法的服务器被变换为HTML存在。

这个问题可以通过这样的默认操作方法创建一个控制器类来解决（我假定目标的错误页面存在于/查看/共享目录）：

public class ErrorController : Controller 
{ 
    public ViewResult Index() 
    { 
     return View("Error"); 
    } 
}

然后，替换defaultRedirect走错了路使用正确的虚拟路径属性：

<customErrors mode="On" defaultRedirect="~/Error" > 
    <error statusCode="404" redirect="~/Error" /> 
</customErrors>

PS：您可以通过添加操作方法，包括Response.StatusCode = [HTML status code]内ErrorController实现超过404其他状态代码自定义错误页。
