我发现了与构建使用C：\ Windows \ System32 \ CertEnroll.dll作为参考的应用相关的问题。
以下代码在Windows 7上使用VS 2015编译然后在Windows 7计算机上运行时工作正常。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using CERTENROLLLib;
namespace CertTest
{
class Program
{
static void Main(string[] args)
{
try
{
CX509PrivateKey key = new CX509PrivateKey();
key.ContainerName = Guid.NewGuid().ToString();
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
}
}
}
当您尝试在Windows 10中编译并尝试在Windows 7计算机上运行它时，会引发以下错误。
“无法将'System .__ ComObject'类型的COM对象转换为接口类型'CERTENROLLLib.CX509PrivateKey'。此操作失败，因为QueryInterface调用COM组件上的IID为”{728AB362-217D-11DA-B2A4“的接口-000E7BBB2B09}由于以下错误而失败：不支持此类接口（HRESULT异常：0x80004002（E_NOINTERFACE））。“
我有几个人在这里复制它，我想在联系微软之前获得更多的意见，以了解这里发生的事情。
我想我的问题是：其他人可以证实这一点，或者是否确认他们违反了兼容性？

以某种方式，CertEnroll.dll上的接口实现在＆＃34; vanilla＆＃34;之间发生了变化。 Windows 2008和Windows 2008 R2。我猜这与一些Windows 7版本是一样的。要使它（中途）工作，你必须使用Activator.CreateInstance(Type.GetTypeFromProgID(<TypeName>)实例化类;
这将导致系统在HKLM中查找引用：\ SOFTWARE \ Classes \ Interface \以获得适合您的类。

那我为什么要写＃34;中途＆＃34;？ certenroll.dll V. 6存在问题，导致构建在cert.InitializeFromPrivateKey上失败。在certenroll.dll V 6.0中，第二个参数必须是＆＃34; CX509PrivateKey＆＃34;类型，而在具有Certenroll.dll V 10的Win10机器上，它的IX509PrivateKey：
错误CS1503：参数2：无法转换为＆＃39; CERTENROLLLib.IX509PrivateKey＆＃39;到＆＃39; CERTENROLLLib.CX509PrivateKey＆＃39;
所以你会想：是的，只是＆＃34;演员＆＃34;上面例子中的privateKey为Activator.CreateInstance上的CX509PrivateKey。这里的问题是，它会编译，但在vanilla Win2k8上它不会给你类（CX509 ...）但是接口（IX509 ...），因此转换失败并返回null。
我们通过在certenroll.dll V 10的机器上的单独项目中编译certenrollment函数来解决这个问题。它编译得很好并且也适用于Win2k8。在一个单独的项目中使用它会让人感到有点恼火，因为使用certenroll.dll V 6构建将在我们的构建服务器上失败。

这些是Microsoft解决此问题的步骤
如果您仅将Windows 10用作构建环境，那么可执行文件将在低级操作系统上运行，但是如果您真的只想拥有一个可以在任何地方编译并在任何地方运行的项目，那么唯一的解决方案是创建自己的互操作您包含在项目文件夹中的DLL。您必须首先在Windows 7上生成它并引用该DLL。
Tlbimp.exe CertEnroll_Interop c：\ Windows \ System32 \ CertEnroll.dll
这将生成一个CertEnroll_Interop.dll文件，您可以将其复制到项目文件夹，然后浏览到项目中。当然，您需要使用“使用CertEnroll_Interop;”语句。
您可以在Windows 10上构建项目，并使其在Windows 7和Windows 8.1以及任何其他组合上运行。
答案 2 :(得分：1)
我遇到了同样的问题，我的开发机器在Windows 10和构建服务器Windows 8.1上运行。
但是由于c＃具有反射和动态类型的能力，我现在首先分析 InitializeFromPrivateKey 方法作为参数的类型（我通过创建方法将其与实际证书代码分开）。 / p>
private static bool IsCompiledOnWin10AndAbove()
{
var typeOfMethod = typeof(IX509CertificateRequestPkcs10);
var methodType = typeOfMethod.GetMethod("InitializeFromPrivateKey", new Type[] { typeof(X509CertificateEnrollmentContext), typeof(CX509PrivateKey), typeof(string) });
var methodeParameters = methodType.GetParameters();
return methodeParameters[1].ParameterType != typeof(CX509PrivateKey);
}
然后使用动态类型，该类型取决于第二个参数的类型。
dynamic privateKeyCorrectType;
if (IsCompiledOnWin10AndAbove()) // win 10 and above compiled
{
privateKeyCorrectType= privateKey;
}
else // below win 10 compiled
{
privateKeyCorrectType= (CX509PrivateKey)privateKey;
}
cert.InitializeFromPrivateKey(X509CertificateEnrollmentContext.ContextMachine, privateKeyCorrectType, "");
