The following example shows the use of members of WindowsIdentity class. 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.

Remarks

Call the GetCurrent method to create a WindowsIdentity object that represents the current user.

Important

This type implements the IDisposable interface. When you have finished using the type, you should dispose of it either directly or indirectly. To dispose of the type directly, call its Dispose method in a try/catch block. To dispose of it indirectly, use a language construct such as using (in C#) or Using (in Visual Basic). For more information, see the "Using an Object that Implements IDisposable" section in the IDisposable interface topic.

Methods

AddClaim(Claim)

Adds a single claim to this claims identity.

(Inherited from ClaimsIdentity)
AddClaims(IEnumerable<Claim>)

Adds a list of claims to this claims identity.

(Inherited from ClaimsIdentity)
Clone()

Creates a new object that is a copy of the current instance.

CreateClaim(BinaryReader)

Provides an extensibility point for derived types to create a custom Claim.

(Inherited from ClaimsIdentity)
Dispose()

Releases all resources used by the WindowsIdentity.

Dispose(Boolean)

Releases the unmanaged resources used by the WindowsIdentity and optionally releases the managed resources.

Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)
Finalize()

Releases the resources held by the current instance.

FindAll(Predicate<Claim>)

Retrieves all of the claims that are matched by the specified predicate.

(Inherited from ClaimsIdentity)
FindAll(String)

Retrieves all of the claims that have the specified claim type.

(Inherited from ClaimsIdentity)
FindFirst(Predicate<Claim>)

Retrieves the first claim that is matched by the specified predicate.

(Inherited from ClaimsIdentity)
FindFirst(String)

Retrieves the first claim with the specified claim type.

(Inherited from ClaimsIdentity)
GetAnonymous()

Returns a WindowsIdentity object that you can use as a sentinel value in your code to represent an anonymous user. The property value does not represent the built-in anonymous identity used by the Windows operating system.

GetCurrent()

Returns a WindowsIdentity object that represents the current Windows user.

GetCurrent(Boolean)

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)

Returns a WindowsIdentity object that represents the current Windows user, using the specified desired token access level.

GetHashCode()

Serves as the default hash function.

(Inherited from Object)
GetObjectData(SerializationInfo, StreamingContext)

Populates the SerializationInfo with data needed to serialize the current ClaimsIdentity object.

(Inherited from ClaimsIdentity)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
HasClaim(Predicate<Claim>)

Determines whether this claims identity has a claim that is matched by the specified predicate.

(Inherited from ClaimsIdentity)
HasClaim(String, String)

Determines whether this claims identity has a claim with the specified claim type and value.

(Inherited from ClaimsIdentity)
Impersonate()

Impersonates the user represented by the WindowsIdentity object.

Impersonate(IntPtr)

Impersonates the user represented by the specified user token.

MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
RemoveClaim(Claim)

Attempts to remove a claim from the claims identity.

(Inherited from ClaimsIdentity)
RunImpersonated(SafeAccessTokenHandle, Action)

Runs the specified action as the impersonated Windows identity. 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>)

Runs the specified function as the impersonated Windows identity. 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.

RunImpersonatedAsync(SafeAccessTokenHandle, Func<Task>)

Runs the specified asynchronous action as the impersonated Windows identity.

RunImpersonatedAsync<T>(SafeAccessTokenHandle, Func<Task<T>>)

Runs the specified asynchronous action as the impersonated Windows identity.

ToString()

Returns a string that represents the current object.

(Inherited from Object)
TryRemoveClaim(Claim)

(Inherited from ClaimsIdentity)
WriteTo(BinaryWriter, Byte[])

Serializes using a BinaryWriter.

(Inherited from ClaimsIdentity)
WriteTo(BinaryWriter)

Serializes using a BinaryWriter.

(Inherited from ClaimsIdentity)

Explicit Interface Implementations

IDeserializationCallback.OnDeserialization(Object)

Implements the ISerializable interface and is called back by the deserialization event when deserialization is complete.
