ASP零：System.IO.FileNotFoundException：找不到文件'c：\\ windows \\ system32 \\ inetsrv \\ log4net.config'

Question

我有一个Web项目，在我更新了一些软件包之前，它仍然可以正常工作，然后在此行代码中遇到运行时错误

    //Log4Net configuration
    AbpBootstrapper.IocManager.IocContainer
        .AddFacility<LoggingFacility>(f => f.UseAbpLog4Net()
            .WithConfig(Server.MapPath("log4net.config"))
        );

错误消息指出即使文件存在，“找不到文件”。

任何答案将不胜感激。 提前致谢。

Answer 1

对于AspNet Core，可以使用HostingEnvironment.ContentRootPath

//Log4Net configuration
AbpBootstrapper
   .IocManager
   .IocContainer
   .AddFacility<LoggingFacility>(f => f.UseAbpLog4Net()
          .WithConfig(Path.Combine(_hostingEnvironment.ContentRootPath, "log4net.config")));

PS：您需要注入IHostingEnvironment

 private readonly IHostingEnvironment _hostingEnvironment;

 public Startup(IHostingEnvironment env)
 {              
    _hostingEnvironment = env;
 }

Update-1：对于AspNet MVC

看看HttpRuntime.AppDomainAppPath

Update-2：对于AspNet MVC-将tilda用于MapPath

Server.MapPath("~\log4net.config")
