Azure上的Log4Net

Question

我已经尝试了所有可以在网上找到的获得log4net与Azure一起工作的东西，但由于大多数文档都非常过时，所以还没有运气。如果任何人有与最新的Azure SDK和Log4Net版本的工作，并可以推动我在正确的方向，将不胜感激。

看起来好像有很多不同的方法来做到这一点，但我还没有像其他许多例子所说的那样，将它追加到表，blob或数据库中。

要使用SQL Azure的或与SQL log4net的在Azure的网站或网页的角色：

在你的数据库创建日志表：

/****** Object: Table [dbo].[Log] Script Date: 4/3/2015 6:32:43 PM 
******/ 
SET ANSI_NULLS OFF 
GO 

SET QUOTED_IDENTIFIER ON 
GO 

SET ANSI_PADDING ON 
GO 

CREATE TABLE [dbo].[Log](
    [ID] [int] IDENTITY(1,1) NOT NULL, 
    [Date] [datetime] NULL, 
    [Level] [nvarchar](50) NULL, 
    [Message] [nvarchar](4000) NULL, 
    [Exception] [nvarchar](4000) NULL, 
    [RemoteHost] [nvarchar](50) NULL, 
    [Cookie] [nvarchar](4000) NULL, 
    [Url] [nvarchar](200) NULL, 
    [QueryString] [nvarchar](1000) NULL, 
    [Referrer] [nvarchar](200) NULL, 
    [RequestMethod] [nvarchar](10) NULL, 
    [ScriptPath] [nvarchar](150) NULL, 
    [UserAgent] [nvarchar](1000) NULL, 
    [Domain] [nvarchar](50) NULL, 
    [CustomBlob] [varchar](max) NULL, 
CONSTRAINT [PrimaryKey_11579ccd-53dd-4bcc-a813-cb4cfb7b6b88] PRIMARY KEY CLUSTERED 
(
    [ID] ASC 
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) 
) 

GO 

SET ANSI_PADDING OFF 
GO 

修改你的web.config文件：
