Windows 10 中的编译问题
Issues compiling in Windows 10
我发现了一个与构建使用 C:\Windows\System32\CertEnroll.dll 作为参考的应用程序相关的问题。
以下代码在 Windows 7 上使用 VS 2015 编译，然后在 Windows 7 机器上使用 运行 编译时工作正常。
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 中编译它，然后在 Windows 7 机器上尝试 运行 时，它会抛出以下错误。
"Unable to cast COM object of type 'System.__ComObject' to interface type 'CERTENROLLLib.CX509PrivateKey'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{728AB362-217D-11DA-B2A4-000E7BBB2B09}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."
这里有几个人复制了它，我想在联系 Microsoft 了解这里发生的事情之前获得更多信息。
我想我的问题是：其他人能否证实这一点，或者如果证实他们破坏了向后兼容性？
CertEnroll.dll 上的接口实现在 "vanilla" Windows 2008 和 Windows 2008 R2 之间以某种方式发生了变化。我想这与某些 Windows 7 版本相同。为了让它（中途）工作，你必须用 Activator.CreateInstance(Type.GetTypeFromProgID(<TypeName>) 实例化 classes;
这将导致系统查找 HKLM:\SOFTWARE\Classes\Interface\ 中的引用，以便为您找到正确的 class。

备注
那我为什么要写"halfway"呢？ 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 "CX509PrivateKey" 类型，而在 Certenroll.dll V 10 的 Win10 机器上，它是 IX509PrivateKey:
error CS1503: Argument 2: cannot convert from 'CERTENROLLLib.IX509PrivateKey' to 'CERTENROLLLib.CX509PrivateKey'
所以你会想：是的，只需将上面示例中的 privateKey "cast" 到 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 class (CX509...) 但接口 (IX509...)，因此转换失败并且 returns null.
我们通过在装有 certenroll.dll V 10 的机器上的单独项目中编译 certenrollment 函数解决了这个问题。它编译得很好，也可以在 Win2k8 中工作。将它放在一个单独的项目中总是有点烦人，因为构建将在我们的构建服务器上失败 certenroll.dll V 6.
这些是 Microsoft 解决此问题的步骤
如果您仅使用 Windows 10 作为您的构建环境，那么可执行文件将 运行 在下层操作系统上，但是如果您真的只是想要一个可以在任何地方编译的项目并且 运行 那么唯一的解决方案是创建自己的互操作 DLL，并将其包含在项目文件夹中。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
这会生成一个 CertEnroll_Interop.dll 文件，您可以将其复制到您的项目文件夹，然后在您的项目中浏览。当然你需要使用“using CertEnroll_Interop;”声明。
您可以在 Windows 10 上构建项目，并在 Windows 7 和 Windows 8.1 以及任何其他组合上拥有它 运行。
我有同样的问题，我的开发机器是 运行 windows 10 和构建服务器 windows 8.1.
但是由于c#有反射和动态类型的能力，我现在先分析一下InitializeFromPrivateKey方法采用哪些类型作为参数（我通过创建将其与实际证书代码分开一种方法）。
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);
}
然后根据第二个参数的类型使用动态类型。
dynamic privateKeyCorrectType;
if (IsCompiledOnWin10AndAbove()) // win 10 and above compiled
{
privateKeyCorrectType= privateKey;
}
else // below win 10 compiled
{
privateKeyCorrectType= (CX509PrivateKey)privateKey;
}
cert.InitializeFromPrivateKey(X509CertificateEnrollmentContext.ContextMachine, privateKeyCorrectType, "");
