Question

ELMAH的创建者提供了一个表创建脚本来记录异常：

CREATE TABLE [dbo].[ELMAH_Error]
(
    [ErrorId]     UNIQUEIDENTIFIER NOT NULL,
    [Application] NVARCHAR(60)  COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
    [Host]        NVARCHAR(50)  COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
    [Type]        NVARCHAR(100) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
    [Source]      NVARCHAR(60)  COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
    [Message]     NVARCHAR(500) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
    [User]        NVARCHAR(50)  COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
    [StatusCode]  INT NOT NULL,
    [TimeUtc]     DATETIME NOT NULL,
    [Sequence]    INT IDENTITY (1, 1) NOT NULL,
    [AllXml]      NVARCHAR(MAX) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL 
)

有人可以告诉我Application和Source应该有什么不同吗？ Application是通过errorLog元素的applicationName属性设置的：

<errorLog type="Elmah.SqlErrorLog, Elmah" connectionStringName="elmah-sqlserver" applicationName="My Cool App"/>

什么是Source？执行程序集的名称？

Answer 1

那应该是包含抛出异常的类的程序集的程序集名称。

示例：

System.Web.HttpException (0x80004005): The controller for path '/scripts/knockout-custombindings' was not found or does not implement IController.
   at System.Web.Mvc.DefaultControllerFactory.GetControllerInstance(RequestContext requestContext, Type controllerType)
   at System.Web.Mvc.DefaultControllerFactory.CreateController(RequestContext requestContext, String controllerName)
   at System.Web.Mvc.MvcHandler.ProcessRequestInit(HttpContextBase httpContext, IController& controller, IControllerFactory& factory)
   at System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContextBase httpContext, AsyncCallback callback, Object state)
   at System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContext httpContext, AsyncCallback callback, Object state)
   at System.Web.Mvc.MvcHandler.System.Web.IHttpAsyncHandler.BeginProcessRequest(HttpContext context, AsyncCallback cb, Object extraData)
   at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

在这种情况下，系统会要求System.Web.Mvc.dll提供一个不存在且未映射到MVC控制器的文件。在这种情况下，Source将等于 System.Web.Mvc 。
