Azure上的Log4Net

Question

我已經嘗試了所有可以在網上找到的獲得log4net與Azure一起工作的東西，但由於大多數文檔都非常過時，所以還沒有運氣。如果任何人有與最新的Azure SDK和Log4Net版本的工作，並可以推動我在正確的方向，將不勝感激。

看起來好像有很多不同的方法來做到這一點，但我還沒有像其他許多例子所說的那樣，將它追加到表，blob或數據庫中。

Answer 1

要使用SQL Azure的或與SQL log4net的在Azure的網站或網頁的角色：

在你的數據庫創建日誌表：

/****** 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：
