X509ChainPolicy.ApplicationPolicy 属性

定义

命名空间:

System.Security.Cryptography.X509Certificates

程序集:

System.Security.Cryptography.dll

Source:

X509ChainPolicy.cs

获取一个对象标识符 (OID) 集合，这些对象标识符指定证书必须支持的应用程序策略或增强型密钥使用 (EKU)。

public:
 property System::Security::Cryptography::OidCollection ^ ApplicationPolicy { System::Security::Cryptography::OidCollection ^ get(); };

public System.Security.Cryptography.OidCollection ApplicationPolicy { get; }

member this.ApplicationPolicy : System.Security.Cryptography.OidCollection

Public ReadOnly Property ApplicationPolicy As OidCollection

属性值

OidCollection

一个 OidCollection 对象。

示例

以下示例打开当前用户的个人证书存储，允许用户选择证书，然后将证书和证书链信息写入控制台。 输出取决于所选证书。

//Output chain information of the selected certificate.
X509Chain ^ ch = gcnew X509Chain;
ch->ChainPolicy->RevocationMode = X509RevocationMode::Online;
ch->Build( certificate );
Console::WriteLine( "Chain Information" );
Console::WriteLine( "Chain revocation flag: {0}", ch->ChainPolicy->RevocationFlag );
Console::WriteLine( "Chain revocation mode: {0}", ch->ChainPolicy->RevocationMode );
Console::WriteLine( "Chain verification flag: {0}", ch->ChainPolicy->VerificationFlags );
Console::WriteLine( "Chain verification time: {0}", ch->ChainPolicy->VerificationTime );
Console::WriteLine( "Chain status length: {0}", ch->ChainStatus->Length );
Console::WriteLine( "Chain application policy count: {0}", ch->ChainPolicy->ApplicationPolicy->Count );
Console::WriteLine( "Chain certificate policy count: {0} {1}", ch->ChainPolicy->CertificatePolicy->Count, Environment::NewLine );

//Output chain information of the selected certificate.
X509Chain ch = new X509Chain();
ch.ChainPolicy.RevocationMode = X509RevocationMode.Online;
ch.Build (certificate);
Console.WriteLine ("Chain Information");
Console.WriteLine ("Chain revocation flag: {0}", ch.ChainPolicy.RevocationFlag);
Console.WriteLine ("Chain revocation mode: {0}", ch.ChainPolicy.RevocationMode);
Console.WriteLine ("Chain verification flag: {0}", ch.ChainPolicy.VerificationFlags);
Console.WriteLine ("Chain verification time: {0}", ch.ChainPolicy.VerificationTime);
Console.WriteLine ("Chain status length: {0}", ch.ChainStatus.Length);
Console.WriteLine ("Chain application policy count: {0}", ch.ChainPolicy.ApplicationPolicy.Count);
Console.WriteLine ("Chain certificate policy count: {0} {1}", ch.ChainPolicy.CertificatePolicy.Count, Environment.NewLine);

'Output chain information of the selected certificate.
Dim ch As New X509Chain()
ch.ChainPolicy.RevocationMode = X509RevocationMode.Online
ch.Build(certificate)
Console.WriteLine("Chain Information")
Console.WriteLine("Chain revocation flag: {0}", ch.ChainPolicy.RevocationFlag)
Console.WriteLine("Chain revocation mode: {0}", ch.ChainPolicy.RevocationMode)
Console.WriteLine("Chain verification flag: {0}", ch.ChainPolicy.VerificationFlags)
Console.WriteLine("Chain verification time: {0}", ch.ChainPolicy.VerificationTime)
Console.WriteLine("Chain status length: {0}", ch.ChainStatus.Length)
Console.WriteLine("Chain application policy count: {0}", ch.ChainPolicy.ApplicationPolicy.Count)
Console.WriteLine("Chain certificate policy count: {0} {1}", ch.ChainPolicy.CertificatePolicy.Count, Environment.NewLine)

注解

默认情况下，此集合为空。 可以使用以下代码将其他对象标识符 (OID) 添加到集合：

X509Chain^ ch = gcnew X509Chain();
ch->ChainPolicy->ApplicationPolicy->Add(gcnew Oid("1.2.1.1"));

X509Chain ch = new X509Chain();
ch.ChainPolicy.ApplicationPolicy.Add(new Oid("1.2.1.1"));

Dim ch As new X509Chain()
ch.ChainPolicy.ApplicationPolicy.Add(new Oid("1.2.1.1"))
