我正在尝试使用log4net的AdoNetAppender将日志写入Sqlite,但我发现它无效。
App.Config中

Log4net.db存储在项目的bin \ Debug中。
申请:
using log4net;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string path = Environment.CurrentDirectory;
AppDomain.CurrentDomain.SetData("DataDirectory", path);
log4net.Config.XmlConfigurator.Configure();
ILog log = LogManager.GetLogger(typeof(Program).FullName);
log.Error("Hello");
}
}
}
运行代码后,我使用&#34; SQLiteStudio&#34;从Log4net.db中选择数据,但我什么都没看到。我的代码会发生什么。

您尝试使用以下连接字符串建立与数据库的连接:
element
SQLite或其依赖项不在您的bin目录中。
