这是我的配置文件,包含log4net属性,如果我使用“RollingLogFileAppender”appender,它会正确写入文件,但我正在使用

(表定义和查询配置来自apache文档,所以我认为连接字符串是我的问题,但应用程序已经与我共享的连接字符串adonet使用的同一数据库连接)

<log4net debug="true">

 ...
<connectionStrings>
    <add name="TedasDbContext" connectionString="metadata=res://*/Project.csdl|res://*/Project.ssdl|res://*/Project.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=****\SQLTEST;initial catalog=LISANSSIZ_SANTRAL_PROJE_ONAY;persist security info=True;user id=user;password=pwd;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
  </connectionStrings>

和.cs文件:

private static readonly ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);

if (log.IsErrorEnabled)
{
    log.Error("Error ocurred here");
}

if (log.IsDebugEnabled)
{
    log.Debug("Debug message");
}

您的缓冲区大小为100,这意味着消息将在100条消息之后写入。将其更改为1,它将直接将消息刷新到sql数据库:

 <bufferSize value="1" />

如果这不起作用,请启用log4net内部调试以查看是否存在连接问题。还要检查您是否有最新版本的log4net。
