c# - 来自 Linux 的 .Net Core Microsoft.Web.Administration ServerManager

Question

.net核心版本:2.1.500

操作系统:Debian 9 (4.9.0-8-amd64 #1 SMP Debian 4.9.130-2 (2018-10-27) x86_64 GNU/Linux)

我试图通过 ServerManager 从 Linux 操作系统停止/启动应用程序池，但没有成功。根据 api 目录，它应该可以工作: https://apisof.net/catalog/Microsoft.Web.Administration.ServerManager

ServerManager.OpenRemote() 在尝试 ApplicationPools 时抛出 NullReference 异常:

// also trying ip adress
using (ServerManager manager = ServerManager.OpenRemote("someserver"))
{
    try
    {
        if (manager.ApplicationPools == null) /* <= Here is exception!!! */
        {
            Console.WriteLine("ApplicationPool is null!");
        }
        else
        {
            foreach (var item in manager.ApplicationPools)
            {
                Console.WriteLine("  " + item.Name);
            }
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine("Exception: " + ex.Message);
        Console.WriteLine(" Trace=" + ex.StackTrace);
    }
}

结果:

Exception: Object reference not set to an instance of an object.
Trace= at Microsoft.Web.Administration.ConfigurationManager.CreateWritableAdminManager(WebConfigurationMap webConfigMap, String configPathToEdit, Boolean isAdminConfig, Boolean isRedirectionConfig) at Microsoft.Web.Administration.ConfigurationManager.CreateConfiguration(WebConfigurationMap configMap, String configPathToEdit, Boolean isAdminConfig, Boolean isRedirectionConfig) at Microsoft.Web.Administration.ConfigurationManager.GetConfiguration(String rawConfigurationPath, String cacheKey, Boolean isAdminConfig, Boolean isRedirectionConfig) at Microsoft.Web.Administration.ServerManager.ApplicationPoolsSectionCreator() at Microsoft.Web.Administration.Lazy.Initialize[T](T& target, CreateInstanceDelegate1 valueFactory)
at Microsoft.Web.Administration.ServerManager.ApplicationPoolCollectionCreator()
at Microsoft.Web.Administration.Lazy.Initialize[T](T& target, CreateInstanceDelegate1 valueFactory) at SomeMethod() in some_file.cs:line 123

当 ServerManager 通过采用字符串 ApplicationPools 的构造函数创建时抛出 System.PlatformNotSupportedException 异常:

using (ServerManager manager = new ServerManager(@"\\someserver\IISSharedConfig\applicationHost.config"))
{
    try
    {
        if (manager.ApplicationPools == null) /* <= Here is exception!!! */
        {
            Console.WriteLine("ApplicationPool is null!");
        }
        else
        {
            foreach (var item in manager.ApplicationPools)
            {
                Console.WriteLine("  " + item.Name);
            }
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine("Exception: " + ex.Message);
        Exception e = ex.InnerException;
        while (e != null)
        {
            Console.WriteLine("InnerException: " + e.Message);
            e = e.InnerException;
        }
        Console.WriteLine(" Trace=" + ex.StackTrace);
    }
}

结果:

Exception: Exception has been thrown by the target of an invocation. InnerException: COM is not supported Trace= at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean wrapExceptions, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor) at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean wrapExceptions, Boolean skipCheckThis, Boolean fillCache) at System.Activator.CreateInstanceT at Microsoft.Web.Administration.ConfigurationManager.CreateAdminManager[TClass,TInterface](WebConfigurationMap webConfigMap, Boolean isAdminConfig, Boolean isRedirectionConfig) at Microsoft.Web.Administration.ConfigurationManager.CreateWritableAdminManager(WebConfigurationMap webConfigMap, String configPathToEdit, Boolean isAdminConfig, Boolean isRedirectionConfig) at Microsoft.Web.Administration.ConfigurationManager.CreateConfiguration(WebConfigurationMap configMap, String configPathToEdit, Boolean isAdminConfig, Boolean isRedirectionConfig) at Microsoft.Web.Administration.ConfigurationManager.GetConfiguration(String rawConfigurationPath, String cacheKey, Boolean isAdminConfig, Boolean isRedirectionConfig) at Microsoft.Web.Administration.ServerManager.ApplicationPoolsSectionCreator() at Microsoft.Web.Administration.Lazy.Initialize[T](T& target, CreateInstanceDelegate1 valueFactory)

如何在Linux中使用ServerManager？

Answer 1

我相信 Linux 不支持您尝试执行的操作。请参阅底部的 link您在问题中发布:

Platform

.NET Standard + Platform Extensions

据我所知，Platform Extensions 是不跨平台的附加项，因此不能用于在 Linux 上运行的应用程序。

您还可以在发布的第二个错误中看到提示:

COM is not supported

这在 Linux 上是正确的。

希望对您有所帮助!
