Ends a pending asynchronous client authentication operation that was started with a call to BeginAuthenticateAsClient.

public:
 virtual void EndAuthenticateAsClient(IAsyncResult ^ asyncResult);

public virtual void EndAuthenticateAsClient (IAsyncResult asyncResult);

abstract member EndAuthenticateAsClient : IAsyncResult -> unit
override this.EndAuthenticateAsClient : IAsyncResult -> unit

Public Overridable Sub EndAuthenticateAsClient (asyncResult As IAsyncResult)

Parameters

asyncResult: IAsyncResult

An IAsyncResult instance returned by a call to BeginAuthenticateAsClient.

Exceptions

ArgumentNullException

asyncResult is null.

ArgumentException

asyncResult was not created by a call to BeginAuthenticateAsClient.

AuthenticationException

The authentication failed. You can use this object to retry the authentication.

InvalidCredentialException

The authentication failed. You can use this object to retry the authentication.

InvalidOperationException

There is no pending client authentication to complete.

Remarks

If the operation has not completed, this method blocks until it does. When the authentication succeeds, you must check the IsEncrypted and IsSigned properties to determine what security services are used by the NegotiateStream. Check the IsMutuallyAuthenticated property to determine whether mutual authentication occurred.

If the authentication fails, you receive an AuthenticationException or an InvalidCredentialException. In this case, you can retry the authentication with a different credential.

To perform this operation synchronously, use one of the AuthenticateAsClient method.
