Question

这看起来很简单。 Elmah记录错误，我在elmah.axd文件中看到错误，然后我想将数据抓取到新的自定义视图中。

我无法弄清楚如何抓住Elma的细节页面。到目前为止，我所能做的就是获取我想要的ErrorLogEntry，但无法弄清楚如何获取服务器吐出的实际XML /异常错误。

Elmah正常成立。但我有：

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

这是我简单的ErrorController.cs类：

public virtual ActionResult Index( )
{
    Exception ex = null;

    try
    {
        Elmah.ErrorLogDataSourceAdapter eldsa = new Elmah.ErrorLogDataSourceAdapter( );
        ErrorLogEntry[] errors = eldsa.GetErrors( 0, 1 );

        foreach ( ErrorLogEntry ele in errors )
        {
            ViewData[ "Description" ] += ele.Error.Message + "<br />";
            ViewData[ "Description" ] += ele.Error.WebHostHtmlMessage + "<br />";
            Elmah.ErrorLogPageFactory pf = new ErrorLogPageFactory( );

        }
    }
    catch
    {
        ViewData[ "Description" ] = "An error occurred.";
    }

    ViewData[ "Title" ] = "Oops. We're sorry. An error occurred and we're on the case.";

    //Email.SendException( ex, "Error in PRISM.NET" );
    return View( );
}

发生的问题是WebHostHtmlMessage为空。所以我无法得到异常消息。

我整天都在查看Elmah代码，我无法弄清楚如何手动创建一个页面就像Elmah在调用elmah.axd时那样。

Answer 1

假设您将数据存储在默认表ELMAH_Error

中

SELECT AllXml
FROM ELMAH_Error

Answer 2

解决方案最终如下：

public virtual ActionResult Index( )
{
    Exception ex = null;

    try
    {
        Elmah.ErrorLogDataSourceAdapter eldsa = new Elmah.ErrorLogDataSourceAdapter( );
        ErrorLogEntry[] errors = eldsa.GetErrors( 0, 1 );

        foreach ( ErrorLogEntry ele in errors )
        {
            ErrorLogEntry thisError = ErrorLog.GetError(ele.Id);
            ex = new Exception( thisError.Error.WebHostHtmlMessage );
        }
    }
    catch
    {
        ViewData[ "Description" ] = "An error occurred.";
    }

    ViewData[ "Description" ] = "Oops. We're sorry. An error occurred and we're on the case.";

    Email.SendException( ex, "Error in PRISM.NET" );
    return View( );
}
