HttpListenerRequest.GetClientCertificateAsync Method

.NET Framework 4.6 and 4.5

Retrieves the client's X.509 v.3 certificate as an asynchronous operation.

Namespace:  System.Net
Assembly:  System (in System.dll)

[HostProtectionAttribute(SecurityAction.LinkDemand, ExternalThreading = true)]
public Task<X509Certificate2> GetClientCertificateAsync()

Return Value

Type: System.Threading.Tasks.Task<X509Certificate2>
Returns Task<TResult>.
The task object representing the asynchronous operation. The Result property on the task object returns a System.Security.Cryptography.X509Certificates object that contains the client's X.509 v.3 certificate.

This operation will not block. The returned Task<TResult> object will complete when the certificate has been retrieved.

If a call to this method to retrieve the client's X.509 v.3 certificate is in progress, then another call to this method cannot be made.

NoteNote

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: ExternalThreading. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.
