AuthorizationContext.cs

評估所有授權原則的結果可從已傳送訊息中的語彙基元或呼叫 GetAuthorizationPolicies(OperationContext) 方法取得。

public ref class AuthorizationContext abstract : System::IdentityModel::Policy::IAuthorizationComponent

備註

評估授權管理員中的所有授權原則會產生一組 ClaimSet 物件。 這些物件會組成授權內容。

授權內容包含一組宣告集物件：指定評估授權內容有效之期間範圍的到期時間，以及唯一的識別項。

目前作業的 AuthorizationContext 可以透過 AuthorizationContext 屬性存取。

建構函式

AuthorizationContext()

初始化 AuthorizationContext 類別的新執行個體。

屬性

ClaimSets	取得與授權原則相關聯的宣告集。
ExpirationTime	取得此 AuthorizationContext 物件不再是有效的日期和時間。
Id	取得此 AuthorizationContext 物件的唯一識別項。
Properties	取得與此 AuthorizationContext 物件相關聯的非宣告屬性集合。

方法

CreateDefaultAuthorizationContext(IList<IAuthorizationPolicy>)	評估所有指定的授權原則並建立 AuthorizationContext。
Equals(Object)	判斷指定的物件是否等於目前的物件。 (繼承來源 Object)
GetHashCode()	做為預設雜湊函式。 (繼承來源 Object)
GetType()	取得目前執行個體的 Type。 (繼承來源 Object)
MemberwiseClone()	建立目前 Object 的淺層複製。 (繼承來源 Object)
ToString()	傳回代表目前物件的字串。 (繼承來源 Object)
