public:
 property System::IdentityModel::Selectors::X509CertificateValidator ^ CustomCertificateValidator { System::IdentityModel::Selectors::X509CertificateValidator ^ get(); void set(System::IdentityModel::Selectors::X509CertificateValidator ^ value); };

public System.IdentityModel.Selectors.X509CertificateValidator CustomCertificateValidator { get; set; }

自定义 X.509 证书验证程序。

示例

下面的代码演示访问和设置此属性的一个方法。

serviceHost.Credentials.ClientCertificate.Authentication.CertificateValidationMode =
    X509CertificateValidationMode.Custom;
serviceHost.Credentials.ClientCertificate.Authentication.CustomCertificateValidator =
    new MyX509CertificateValidator("CN=Contoso.com");

下面的代码定义前面代码中引用的自定义验证程序。

public class MyX509CertificateValidator : X509CertificateValidator
{
    string allowedIssuerName;

    public MyX509CertificateValidator(string allowedIssuerName)
    {
        if (allowedIssuerName == null)
        {
            throw new ArgumentNullException("allowedIssuerName");
        }

        this.allowedIssuerName = allowedIssuerName;
    }

    public override void Validate(X509Certificate2 certificate)
    {
        // Check that there is a certificate.
        if (certificate == null)
        {
            throw new ArgumentNullException("certificate");
        }

        // Check that the certificate issuer matches the configured issuer.
        if (allowedIssuerName != certificate.IssuerName.Name)
        {
            throw new SecurityTokenValidationException
              ("Certificate was not issued by a trusted issuer");
        }
    }
}
