GetCurrentDirectory returns the worker directory of the process started by IIS rather than the app's directory (for example, C:\Windows\System32\inetsrv for w3wp.exe).html

which means config loader will not be able to find appsettings.* files, or any other files such as custom config files, that depend on a GetCurrentDirectory call. In order to solve it in your Program.cs right after public static void Main(string[] args) { add the following linelinux

Directory.SetCurrentDirectory(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location));

解决方式

主动设置一下当前目录为程序根目录：

System.IO.Directory.SetCurrentDirectory(hostingEnvironment.ContentRootPath);
XML 
<?xml version="1.0" encoding="utf-8"?> <configuration> <location path="." inheritInChildApplications="false"> <system.webServer> <handlers> <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" /> </handlers> <aspNetCore processPath="dotnet" arguments=".\MyApp.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="InProcess" /> </system.webServer> </location> </configuration>

如下 web.config 发布用于独立部署：

XML 



<PropertyGroup> <AspNetCoreHostingModel>OutOfProcess</AspNetCoreHostingModel> </PropertyGroup>

<?xml version="1.0" encoding="utf-8"?> <configuration> <location path="." inheritInChildApplications="false"> <system.webServer> <handlers> <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" /> </handlers> <aspNetCore processPath=".\MyApp.exe" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="InProcess" /> </system.webServer> </location> </configuration>
Directory.SetCurrentDirectory(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location));

Try changing the section in csproj

<PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
  </PropertyGroup>

to the following ...

<PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <AspNetCoreHostingModel>OutOfProcess</AspNetCoreHostingModel>
    <AspNetCoreModuleName>AspNetCoreModule</AspNetCoreModuleName>
 </PropertyGroup>

Solution is to have a static reference to the LoggerFactory in a utility static class initialized on startup:

/// <summary>
    /// Shared logger
    /// </summary>
    internal static class ApplicationLogging
    {
        internal static ILoggerFactory LoggerFactory { get; set; }// = new LoggerFactory();
        internal static ILogger CreateLogger<T>() => LoggerFactory.CreateLogger<T>();        
        internal static ILogger CreateLogger(string categoryName) => LoggerFactory.CreateLogger(categoryName);

    }

Which you intialize on Startup.cs:

public Startup(ILogger<Startup> logger, ILoggerFactory logFactory, IHostingEnvironment hostingEnvironment)
        {
            _log = logger;
            _hostingEnvironment = hostingEnvironment;
            Util.ApplicationLogging.LoggerFactory = logFactory;//<===HERE

        }

Then you can build a logger to use from your static class like so:

internal static class CoreJobSweeper
    {
        private static ILogger log = Util.ApplicationLogging.CreateLogger("CoreJobSweeper");

Profiling the .NET Core Application on Linux

To gather detailed information about a performance issue of .NET Core Application on Linux, you can follow the simple instructions here:

  1. Download perfcollect script provided by .NET Core team.
    curl -OL http://aka.ms/perfcollect
  2. Make the script executable.
    chmod +x perfcollect
  3. Install prerequisites (perf and LTTng):
    sudo ./perfcollect install
  4. Setup the application shell and enables tracing configuration:
    export COMPlus_PerfMapEnabled=1
    export COMPlus_EnableEventLog=1
  5. Run collection:
    ./perfcollect collect tracefile
  6. Copy the tracefile.zip file to a Windows machine.
  7. Download PerfView on Windows box.
  8. Open the trace in PerfView, then you can explore the CPU sampling data. Flame Graph is also available here.
    Using BPF Complier Collection (BCC) is another good choice for performance analysis as BPF is more flexible and efficiency. Please follow the tutorial of BCC.

若是这是WPF,那么我肯定你会在某种事件发生时调用它.你应该调用这个方法的方法来自事件处理程序,例如：

 

private async void OnWindowOpened(object sender, EventArgs args) { await Execute(); }

看看你的问题的编辑版本,我能够看到,实际上你能够经过使用异步版本的DownloadStringAsync使它变得很是漂亮和漂亮：

 

private async Task ReadImages (string HTMLtag) { string section = HTMLtag.Split(':')[0]; string tag = HTMLtag.Split(':')[1]; List<string> UsedAdresses = new List<string>(); var webClient = new WebClient(); string page = await webClient.DownloadStringAsync(Link); //... }

如今,处理任务是什么.添加(Task.Run(()=> ReadImages(tag)));?
