using System.Runtime.InteropServices;
// Add the following as a COM reference - C:\WINDOWS\Microsoft.NET\Framework\vXXXXXX\mscoree.tlb
using mscoree;                              

        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);
            }
        } 
    }

VB.NET:

<System.Runtime.CompilerServices.CompilerGenerated>
<System.Runtime.InteropServices.Guid("CB2F6722-AB3A-11D2-9C40-00C04FA30A3E")>
<System.Runtime.InteropServices.InterfaceType(Runtime.InteropServices.ComInterfaceType.InterfaceIsIUnknown)>
<System.Runtime.InteropServices.ComImport>
<System.CLSCompliant(False)>
Interface ICorRuntimeHost
    Sub _VtblGap1_11()
    Sub EnumDomains(<System.Runtime.InteropServices.Out> ByRef enumHandle As IntPtr)
    Sub NextDomain(<System.Runtime.InteropServices.[In]> ByVal enumHandle As IntPtr, <System.Runtime.InteropServices.Out> <System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.IUnknown)> ByRef appDomain As Object)
    Sub CloseEnum(<System.Runtime.InteropServices.[In]> ByVal enumHandle As IntPtr)
End Interface

Private Function GetCorRuntimeHost() As ICorRuntimeHost
    Return CType(Activator.CreateInstance(System.Type.GetTypeFromCLSID(New Guid("CB2F6723-AB3A-11D2-9C40-00C04FA30A3E"))), ICorRuntimeHost)
End Function

Public Function GetAppDomains() As List(Of AppDomain)
    Dim ls As List(Of AppDomain) = New List(Of AppDomain)
    Dim enumHandle As IntPtr = IntPtr.Zero

    Dim host As ICorRuntimeHost = GetCorRuntimeHost()

    Try
        host.EnumDomains(enumHandle)
        Dim domain As Object = Nothing

        While True
            host.NextDomain(enumHandle, domain)
            If domain Is Nothing Then Exit While
            Dim appDomain As AppDomain = CType(domain, AppDomain)
            ls.Add(appDomain)
        End While

        Return ls
    Catch e As Exception
        Console.WriteLine(e.ToString())
        Return Nothing
    Finally
        host.CloseEnum(enumHandle)
        Runtime.InteropServices.Marshal.ReleaseComObject(host)
    End Try
End Function

使用法：

Dim ls As List(Of AppDomain) = GetAppDomains()
System.Console.WriteLine(ls)
