问题:无法使用CLR存储过程内的Log4net调试(写入)日志文件。我正在构建CLR项目的方式可能有问题吗?我只是将DLL导入sql server(创建程序集....)。我是否还需要导入App.Config?
DLL名称: CLRTest.dll
源代码:
using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using System.Data.SqlTypes;
using System.Data.SqlClient;
using Microsoft.SqlServer.Server;
using log4net;
using log4net.Config;
public class MyClass
{
private readonly static ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
private static readonly string sContextConn = "Context Connection=true";
[Microsoft.SqlServer.Server.SqlProcedure]
public static void Select1()
{
XmlConfigurator.Configure();
log.Debug("Begin Select1()...");
using (SqlConnection connection = new SqlConnection(sContextConn))
{
connection.Open();
SqlCommand command = new SqlCommand("select 1", connection);
SqlDataReader r = command.ExecuteReader();
SqlContext.Pipe.Send(r);
}
log.Debug("End Select1()...");
}
}//end MyClass
Log4Net XML Config(App.Config):
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>
<log4net>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="C:\log\clrsql.log" />
<param name="AppendToFile" value="true" />
<datePattern value="yyyyMMdd-HHmm" />
<param name="rollingStyle" value="Size" />
<param name="maxSizeRollBackups" value="50" />
<param name="maximumFileSize" value="25MB" />
<param name="staticLogFileName" value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%d %-5p [t-%t] [%c.%M(%L)] %m%n" />
</layout>
</appender>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%d %-5p [%c.%M(%L)] %m%n" />
</layout>
</appender>
<root>
<level value="DEBUG" />
<appender-ref ref="RollingFileAppender" />
<appender-ref ref="ConsoleAppender" />
</root>
</log4net>
SQL Server的权限:
C:\ log \ - NETWORK SERVICE和MyDomain \ sqlserveraccount对“log”文件夹具有完全控制权。
SQL脚本:
drop procedure clr_Select1
go
drop assembly CLRTest
go
create ASSEMBLY CLRTest FROM 'C:\Share\ClrSql\TEST\CLRTest.dll' WITH PERMISSION_SET = unsafe
go
CREATE PROCEDURE clr_Select1
AS EXTERNAL NAME CLRTest.MyClass.Select1
go
exec clr_Select1
SQL输出:

您正在进行的log4net配置程序调用实际上会尝试查找AppDomain.CurrentDomain.SetupInformation.ConfigurationFile
。我不知道AppDomain
对于存储过程是什么。
您可能想尝试standalone配置文件并使用该配置程序的重载。
log4net.Config.XmlConfigurator.Configure(new FileInfo("config.log4net"));
