Esempi

Nell'esempio seguente viene illustrato l'utilizzo dei membri WindowsIdentity della classe.The following example shows the use of members of WindowsIdentity class. Per un esempio che illustra come ottenere un token di account Windows tramite una chiamata alla funzione Win32 LogonUser non gestita e usare tale token per rappresentare un altro utente, vedere la WindowsImpersonationContext classe.For an example showing how to obtain a Windows account token through a call to the unmanaged Win32 LogonUser function, and use that token to impersonate another user, see the WindowsImpersonationContext class.

Chiamare il GetCurrent metodo per creare un WindowsIdentity oggetto che rappresenta l'utente corrente.Call the GetCurrent method to create a WindowsIdentity object that represents the current user.

Importante

Il tipo implementa l'interfaccia IDisposable.This type implements the IDisposable interface. Dopo aver utilizzato il tipo, è necessario eliminarlo direttamente o indirettamente.When you have finished using the type, you should dispose of it either directly or indirectly. Per eliminare direttamente il tipo, chiamare il metodo Dispose in un blocco try/catch.To dispose of the type directly, call its Dispose method in a try/catch block. Per eliminarlo indirettamente, utilizzare un costrutto di linguaggio come ad esempio using in C# o Using in Visual Basic.To dispose of it indirectly, use a language construct such as using (in C#) or Using (in Visual Basic). Per altre informazioni, vedere la sezione "Uso di un oggetto che implementa IDisposable" nell'argomento relativo all'interfaccia IDisposable.For more information, see the "Using an Object that Implements IDisposable" section in the IDisposable interface topic.

Metodi

Clone()

Crea un nuovo oggetto che è una copia dell'istanza corrente.Creates a new object that is a copy of the current instance.

Dispose()

Rilascia tutte le risorse usate da WindowsIdentity.Releases all resources used by the WindowsIdentity.

Dispose(Boolean)

Rilascia le risorse non gestite usate da WindowsIdentity e, facoltativamente, le risorse gestite.Releases the unmanaged resources used by the WindowsIdentity and optionally releases the managed resources.

Equals(Object)

(Ereditato da Object)
Finalize()

Rilascia le risorse contenute nell'istanza corrente.Releases the resources held by the current instance.

GetAnonymous()

Restituisce un oggetto WindowsIdentity che è possibile usare nel codice come valore di sentinel per rappresentare un utente anonimo.Returns a WindowsIdentity object that you can use as a sentinel value in your code to represent an anonymous user. Il valore della proprietà non rappresenta l'identità anonima predefinita usata dal sistema operativo Windows.The property value does not represent the built-in anonymous identity used by the Windows operating system.

GetCurrent()

GetCurrent(Boolean)

Restituisce un oggetto WindowsIdentity che rappresenta l'identità Windows del thread o del processo, a seconda del valore del parametro ifImpersonating.Returns a WindowsIdentity object that represents the Windows identity for either the thread or the process, depending on the value of the ifImpersonating parameter.

GetCurrent(TokenAccessLevels)

Restituisce un oggetto WindowsIdentity che rappresenta l'utente Windows corrente, usando il livello di accesso del token specificato.Returns a WindowsIdentity object that represents the current Windows user, using the specified desired token access level.

GetHashCode()

(Ereditato da Object)
GetType()

Ottiene l'oggetto Type dell'istanza corrente.Gets the Type of the current instance.

(Ereditato da Object)
Impersonate()

Rappresenta l'utente definito dall'oggetto WindowsIdentity.Impersonates the user represented by the WindowsIdentity object.

Impersonate(IntPtr)

Rappresenta l'utente definito dal token utente specificato.Impersonates the user represented by the specified user token.

MemberwiseClone()

Crea una copia superficiale dell'oggetto Object corrente.Creates a shallow copy of the current Object.

(Ereditato da Object)
RunImpersonated(SafeAccessTokenHandle, Action)

Esegue l'azione specificata come identità Windows rappresentata.Runs the specified action as the impersonated Windows identity. Anziché usare una chiamata al metodo rappresentato ed eseguire la funzione in WindowsImpersonationContext, è possibile usare RunImpersonated(SafeAccessTokenHandle, Action) e fornire la funzione direttamente come parametro.Instead of using an impersonated method call and running your function in WindowsImpersonationContext, you can use RunImpersonated(SafeAccessTokenHandle, Action) and provide your function directly as a parameter.

RunImpersonated<T>(SafeAccessTokenHandle, Func<T>)

Esegue la funzione specificata come identità Windows rappresentata.Runs the specified function as the impersonated Windows identity. Anziché usare una chiamata al metodo rappresentato ed eseguire la funzione in WindowsImpersonationContext, è possibile usare RunImpersonated(SafeAccessTokenHandle, Action) e fornire la funzione direttamente come parametro.Instead of using an impersonated method call and running your function in WindowsImpersonationContext, you can use RunImpersonated(SafeAccessTokenHandle, Action) and provide your function directly as a parameter.

ToString()

Restituisce una stringa che rappresenta l'oggetto corrente.Returns a string that represents the current object.
