      X509Store ^ store = gcnew X509Store( "MY",StoreLocation::CurrentUser );
      store->Open( static_cast<OpenFlags>(OpenFlags::ReadOnly | OpenFlags::OpenExistingOnly) );
      X509Certificate2Collection ^ collection = dynamic_cast<X509Certificate2Collection^>(store->Certificates);
      X509Certificate2Collection ^ fcollection = dynamic_cast<X509Certificate2Collection^>(collection->Find( X509FindType::FindByTimeValid, DateTime::Now, false ));
      X509Certificate2Collection ^ scollection = X509Certificate2UI::SelectFromCollection(fcollection, "Test Certificate Select","Select a certificate from the following list to get information on that certificate",X509SelectionFlag::MultiSelection);
      Console::WriteLine( "Number of certificates: {0}{1}", scollection->Count, Environment::NewLine );
      System::Collections::IEnumerator^ myEnum = scollection->GetEnumerator();
      while ( myEnum->MoveNext() )
      {
         X509Certificate2 ^ x509 = safe_cast<X509Certificate2 ^>(myEnum->Current);
         X500DistinguishedName ^ dname = gcnew X500DistinguishedName( x509->SubjectName );
         Console::WriteLine( "X500DistinguishedName: {0}{1}", dname->Name, Environment::NewLine );

注解

此类类似于或IssuerName属性的扩展，该扩展SubjectName是颁发证书的人员或实体的名称。 X.500 是分布式目录服务的国际标准。可分辨名称使用以下格式：

[X500：/C=CountryCode/O=Organization/OU=OrganizationUnit/CN=CommonName]

以下字段长度限制适用：

字段	长度限制
CountryCode	2 个字符
组织	最多 64 个字符
OrganizationUnit	最多 32 个字符
CommonName	最多 64 个字符

以下准则将适用：

字段值可以是大写或小写。
分隔符是 (/) 的斜杠标记，必须在第一个值和后续值之间显示。
分隔符后跟空格。

下面是格式正确的名称示例：[X500：/C=US/ O=Microsoft/ OU=WGA/ CN=TedSt]

构造函数

X500DistinguishedName(AsnEncodedData)	使用指定的 AsnEncodedData 对象初始化 X500DistinguishedName 类的新实例。
