无法获取与.NET Framework 4.0 Process相关的应用程序域的数据 [英] Not able to fetch data for Application Domains related to .NET Framework 4.0 Process

问题描述

我们要枚举特定计算机上的所有.NET Framework 4.0进程.然后要枚举这些进程的应用程序域.

We want to enumerate all .NET Framework 4.0 Processes on a particular machine. And then want to enumerate Application Domains for those processes.

枚举应用程序域后，我们希望使用以下API来获取有关每个应用程序域的数据.

After enumerating Application Domains, we want to fetch data about each Application Domain using following APIs.

ICLRAppDomainResourceMonitor :: GetCurrentAllocated

ICLRAppDomainResourceMonitor::GetCurrentSurvived

我们使用ICorPublishAppDomain接口以及以下代码进行了尝试:

We tried this using ICorPublishAppDomain Interface as well as following code :

ICLRMetaHost *meta; 
ICLRRuntimeInfo *info; 
ICLRRuntimeHost *host; 
ICLRControl *control; 
ICLRAppDomainResourceMonitor *monitor; 

CLRCreateInstance(CLSID_CLRMetaHost, IID_ICLRMetaHost, (void **)&meta); 
meta->GetRuntime(L"v4.0.30319", IID_CLRRuntimeInfo, (void **)&runtime); 
info->GetInterface(CLSID_CLRRuntimeHost, IID_ICLRRuntimeHost, (void **)&host); 
host->GetCLRControl(&control); 
control->GetCLRManager(IID_ICLRAppDomainResourceMonitor, (void **)&monitor); 

 
// ... rest of CLR startup ... 
 
unsigned long long bytes; 
monitor->GetCurrentAllocated(1, &bytes); 

但是，我们无法枚举系统上每个.NET Framework 4.0进程的应用程序域.

However, we couldnt enumerate App Domains for each .NET Framework 4.0 process on a system.

任何人都可以帮助我吗?非常感谢.

推荐答案

嗨奥迪，

令人惊讶的是，BCL中没有可管理的API来显示AppDomains L 使用 但是，互操作性可以列出AppDomain:

Surprisingly there is no managed API in the BCL to show AppDomains L Using Interop however, we can list the AppDomains:

using System.Runtime.InteropServices;       // for domain enum
using mscoree;                              // for domain enum. Add the following as a COM reference - C:\WINDOWS\Microsoft.NET\Framework\vXXXXXX\mscoree.tlb
namespace MyNS
{
    public class ListProcessAppDomains
    {
        public static IList<AppDomain> GetAppDomains()
        {
            IList<AppDomain> _IList = new List<AppDomain>();
            IntPtr enumHandle = IntPtr.Zero;
            CorRuntimeHostClass host = new mscoree.CorRuntimeHostClass();
            try
            {
                host.EnumDomains(out enumHandle);
                object domain = null;
                while (true)
                {
 
                    host.NextDomain(enumHandle, out domain);
                    if (domain == null) break;
                    AppDomain appDomain = (AppDomain)domain;
                    _IList.Add(appDomain);
                }
                return _IList;
            }
            catch (Exception e)
            {
                Console.WriteLine(e.ToString());
                return null;
            }
            finally
            {
                host.CloseEnum(enumHandle);
                Marshal.ReleaseComObject(host);
            }
        }
    }
