X509Chain.Build(X509Certificate2) 方法

定義

使用 X509ChainPolicy 中指定的原則,建置 X.509 鏈結。

public:
 bool Build(System::Security::Cryptography::X509Certificates::X509Certificate2 ^ certificate);
public bool Build (System.Security.Cryptography.X509Certificates.X509Certificate2 certificate);
[System.Runtime.Versioning.UnsupportedOSPlatform("browser")]
public bool Build (System.Security.Cryptography.X509Certificates.X509Certificate2 certificate);
member this.Build : System.Security.Cryptography.X509Certificates.X509Certificate2 -> bool
[<System.Runtime.Versioning.UnsupportedOSPlatform("browser")>]
member this.Build : System.Security.Cryptography.X509Certificates.X509Certificate2 -> bool
Public Function Build (certificate As X509Certificate2) As Boolean

參數

certificate
X509Certificate2

X509Certificate2 物件。

傳回

Boolean

如果 X.509 憑證有效,則為 true,否則為 false

屬性

例外狀況

certificate 不是有效憑證或是 null

certificate 無法讀取。

範例

下列程式碼範例會開啟目前使用者的個人憑證存儲,讓您選取憑證,然後將憑證和憑證鏈結資訊寫入主控台。 輸出取決於您選取的憑證。

//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)

備註

請注意,來自受信任簽發者的有效 X.509 憑證僅適用于 物件中指定的 X509ChainPolicy 使用。 符合這些鏈結原則規則的憑證對於具有安全性/MIME (SMIME) 、Authenticode 或 Secure Sockets Layer (SSL) 等功能的特定用途,可能仍然無效。 如果需要進一步處理,才能判斷憑證是否對特定原則有效,請從 X509Chain 衍生類別並覆寫 Build 方法,以便先呼叫基類 Build 方法,然後執行其他處理。
