AuthorizationContext Class
The result of evaluating all authorization policies available from the tokens in the sent message and by calling the GetAuthorizationPolicies method.
Assembly: System.IdentityModel (in System.IdentityModel.dll)
The AuthorizationContext type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | AuthorizationContext | Initializes a new instance of the AuthorizationContext class. |
| Name | Description | |
|---|---|---|
![]() | ClaimSets | Gets the set of claims associated with an authorization policy. |
![]() | ExpirationTime | Gets the date and time at which this AuthorizationContext object is no longer valid. |
![]() | Id | Gets a unique identifier for this AuthorizationContext object. |
![]() | Properties | Gets a collection of non-claim properties associated with this AuthorizationContext object. |
| Name | Description | |
|---|---|---|
![]() ![]() | CreateDefaultAuthorizationContext | Evaluate all of the specified authorization policies and create an AuthorizationContext. |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
Evaluating all of the authorization policies in an authorization manager results in a set of ClaimSet objects. These objects make up an authorization context.
An authorization context contains a set of claim set objects, an expiration time that specifies the span of time during which the authorization context is valid, and a unique identifier.
The AuthorizationContext for the current operation can be accessed via the AuthorizationContext property.
Protected Overrides Function CheckAccessCore(ByVal operationContext As OperationContext) As Boolean ' Extract the action URI from the OperationContext.
