Question

我正在测试Log4Net，并且能够写入文本文件，事件查看器。我试图用MS SQL 2008 Express测试它，我似乎无法将其插入到我在本地创建的数据库中。

实例:(本地）

数据库名称：Log4Net

我在下面的配置中省略了连接字符串上的用户ID和密码，因为我在本地运行它：

<log4net debug="true">
        <!--
            APPENDING TO A TEXT FILE

            <rollingStyle value="Size" />
            <maxSizeRollBackups value="10" />

            <parameter>

                <dbType value="String" />
                <size value="2000" />
                <layout type="log4net.Layout.ExceptionLayout" />
            </parameter>
        </appender>



        <root>
            <level value="DEBUG" />
            <appender-ref ref="AdoNetAppender" />
        </root>
    </log4net>

这是测试C＃代码：

 if (log.IsDebugEnabled)
                {
                    log.Debug("Insert some useful comment..");
                }

                if (log.IsErrorEnabled)
                {
                    log.Error("Some Error blah blah.. Testing Only..");
                }

P.S。我肯定已经创建了“Log”表。

如果要从连接字符串中省略用户ID和密码，则需要设置integrated security=true。

无法使用Log4Net插入到MSSQL表中
