SSL认证链不适用于自签名证书(SSL chain of certification not working for a self signed certificate)

 客户给了我们3个证书，这些证书按顺序安装在Windows服务器上，并且：  
 
  由Verisign发布，适用于Symantec（仅限证书，作为中间件安装）  
  Symantec发布，适用于CompanyX（仅限证书，安装为中间版）  
  CompanyX发布，适用于CompanyX（证书和密钥，安装为个人）  
 
 在mmc中，当我检查＃2时，我可以看到链为：  
 Verisign（root） - > Verisign（中间） - > Symantec（中级）  
 检查＃3（自签名证书）时，没有链。 只有CompanyX。  
 似乎Windows无法在最后一个中间证书和自签名证书之间建立链，因此当客户端连接到Web服务器时，他们会看到自签名或不受信任的证书警告，可能是因为服务器未发布中间证书。  
 我已经验证了通用名称是否完全匹配，并重复了几次安装程序。 我在安装证书时做错了吗？ 我错过了什么吗？ 

A customer has given us 3 certificates, which were installed on a windows server in the order and : 
 
 Issued by Verisign, for Symantec (certificate only, installed as intermediate) 
 Issued by Symantec, for CompanyX (certificate only, installed as intermediate) 
 Issued by CompanyX, for CompanyX (certificate and key, installed as Personal) 
 
In mmc, when I inspect #2, I can see the chain as: 
Verisign (root) -> Verisign (intermediate) --> Symantec (intermediate) 
When inspecting #3 (the self signed certificate), there is no chain. There's only CompanyX. 
Seems like windows is failing to establish the chain between the last intermediate and the self signed certificate, so when clients connect to the web server, they see a self-signed or untrusted certificate warning, presumably because the server is not publishing the intermediate certificates. 
I've already verified that common names match exactly, and repeated the installation procedures a few times. Did I do something wrong installing the certificates? Am I missing something?

 你需要使用反射。 MakeGenericType允许您使用特定的泛型参数获取Type ，然后您可以根据需要获取并调用任何方法。  
void Main()
{
    Type t = typeof(int);
    Type at = typeof(A<>).MakeGenericType(t);
    at.GetMethod("B").Invoke(null, new object[]{"test"});
}

public class A<T>
{
    public static void B(string s)
    {
        Console.WriteLine(s+" "+typeof(T).Name);
    }
}
 
 作为性能优化，您可以使用反射来获取每种类型的委托，然后您可以调用它而无需进一步反映。  
Type t = typeof(int);
Type at = typeof(A<>).MakeGenericType(t);
Action<string> action = (Action<string>)Delegate.CreateDelegate(typeof(Action<string>), at.GetMethod("B"));
action("test");

You need to use reflection. MakeGenericType allows you to get the Type with specific generic arguments and then you can get and call any method on it as you like. 
void Main()
{
    Type t = typeof(int);
    Type at = typeof(A<>).MakeGenericType(t);
    at.GetMethod("B").Invoke(null, new object[]{"test"});
}

public class A<T>
{
    public static void B(string s)
    {
        Console.WriteLine(s+" "+typeof(T).Name);
    }
}
 
As a performance optimization you could use reflection to get a delegate for each type which you then can invoke without further reflection. 
Type t = typeof(int);
Type at = typeof(A<>).MakeGenericType(t);
Action<string> action = (Action<string>)Delegate.CreateDelegate(typeof(Action<string>), at.GetMethod("B"));
action("test");
