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

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

public virtual void EndAuthenticateAsServer(
	IAsyncResult asyncResult
)

Parameters

asyncResult
Type: System.IAsyncResult

An IAsyncResult instance returned by a call to BeginAuthenticateAsServer.

Exception Condition
ArgumentNullException

asyncResult is null.

ArgumentException

asyncResult was not created by a call to BeginAuthenticateAsServer.

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 authentication to complete.

If the operation has not completed, this method blocks until it does.

When 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 the AuthenticateAsServer method.
