注解

方法 Unregister 从 方法调用 Authenticate 的身份验证模块列表中删除指定的身份验证模块。 必须先使用 方法将该模块添加到列表中， Register 然后才能将其从列表中删除。

Unregister(String)

Source:

AuthenticationManager.cs

将具有指定身份验证方案的身份验证模块从已注册模块列表中移除。

public:
 static void Unregister(System::String ^ authenticationScheme);

public static void Unregister (string authenticationScheme);

static member Unregister : string -> unit

Public Shared Sub Unregister (authenticationScheme As String)

参数

authenticationScheme

String

要移除的模块的身份验证方案。

例外

ArgumentNullException

authenticationScheme 为 null。

InvalidOperationException

此身份验证方案的模块没有注册。

示例

以下示例使用 Unregister 方法从已注册模块列表中删除具有指定身份验证方案的身份验证模块。

IEnumerator^ registeredModules = AuthenticationManager::RegisteredModules;
// Display all the modules that are already registered with the system.
DisplayAllModules();
registeredModules->Reset();
registeredModules->MoveNext();
// Get the first Authentication module registered with the system.
IAuthenticationModule^ authenticationModule1 = dynamic_cast<IAuthenticationModule^>(registeredModules->Current);
// Call the UnRegister() method to unregister the first authentication module from the system.
String^ authenticationScheme = authenticationModule1->AuthenticationType;
AuthenticationManager::Unregister( authenticationScheme );
Console::WriteLine(  "\nSuccessfully unregistered '{0}'.", authenticationModule1 );
// Display all modules to see that the module was unregistered.
DisplayAllModules();

IEnumerator registeredModules = AuthenticationManager.RegisteredModules;
// Display all the modules that are already registered with the system.
DisplayAllModules();
registeredModules.Reset();
registeredModules.MoveNext();
// Get the first Authentication module registered with the system.
IAuthenticationModule authenticationModule1 = (IAuthenticationModule)registeredModules.Current;
// Call the UnRegister() method to unregister the first authentication module from the system.
String authenticationScheme = authenticationModule1.AuthenticationType;
AuthenticationManager.Unregister(authenticationScheme);
Console.WriteLine("\nSuccessfully unregistered '{0}",authenticationModule1+"'.");
// Display all modules to see that the module was unregistered.
DisplayAllModules();

Dim registeredModules As IEnumerator = AuthenticationManager.RegisteredModules
DisplayAllModules()

registeredModules.Reset()
registeredModules.MoveNext()

'Get the first Authentication module registered with the system
Dim authenticationModule1 As IAuthenticationModule = CType(registeredModules.Current, IAuthenticationModule)

'Call the UnRegister method to unregister the first authentication module from the system.
Dim authenticationScheme As [String] = authenticationModule1.AuthenticationType
AuthenticationManager.Unregister(authenticationScheme)
Console.WriteLine(ControlChars.Cr + "Successfully unregistered {0}", authenticationModule1)
'Display all modules to see that the module was unregistered.
DisplayAllModules()
'Call the Register method to register authenticationModule1 module again.
AuthenticationManager.Register(authenticationModule1)
Console.WriteLine(ControlChars.Cr + "Successfully re-registered {0}", authenticationModule1)
'Display the modules to verify that 'authenticationModule1' has been registered again.
DisplayAllModules()
