注解

GetCurrent调用 方法以创建表示WindowsIdentity当前用户的对象。

重要

此类型实现 IDisposable 接口。 在使用完类型后，您应直接或间接释放类型。 若要直接释放类型，请在 try/catch 块中调用其 Dispose 方法。 若要间接释放类型，请使用 using（在 C# 中）或 Using（在 Visual Basic 中）等语言构造。 有关详细信息，请参阅 IDisposable 接口主题中的“使用实现 IDisposable 的对象”一节。

WindowsIdentity(IntPtr, String, WindowsAccountType, Boolean)	为指定的 Windows 帐户标记、指定的身份验证类型、指定的 Windows 帐户类型和指定的身份验证状态表示的用户初始化 WindowsIdentity 类的新实例。
WindowsIdentity(SerializationInfo, StreamingContext)	已过时. 初始化 SerializationInfo 流中的信息所表示的用户的 WindowsIdentity 类的新实例。

FindAll(Predicate<Claim>)	检索所有与指定谓词相匹配的声明。 (继承自 ClaimsIdentity)
FindAll(String)	检索所有有指定声明类型的声明。 (继承自 ClaimsIdentity)
FindFirst(Predicate<Claim>)	检所由指定谓词匹配的第一个声明。 (继承自 ClaimsIdentity)
FindFirst(String)	检索有指定声明类型的第一个声明。 (继承自 ClaimsIdentity)
GetAnonymous()	返回 WindowsIdentity 对象，可在代码中将其用作 sentinel 值来表示匿名用户。 属性值不表示 Windows 操作系统使用的内置匿名标识。
GetCurrent()	返回表示当前 Windows 用户的 WindowsIdentity 对象。
GetCurrent(Boolean)	返回一个 WindowsIdentity 对象，该对象表示线程或进程（具体取决于 ifImpersonating 参数的值）的 Windows 标识。
GetCurrent(TokenAccessLevels)	返回一个 WindowsIdentity 对象，该对象使用指定的所需标记访问级别来表示当前 Windows 用户。
GetHashCode()	作为默认哈希函数。 (继承自 Object)
GetObjectData(SerializationInfo, StreamingContext)	用序列化当前SerializationInfo 对象所需的数据来填充 ClaimsIdentity。 (继承自 ClaimsIdentity)
GetType()	获取当前实例的 Type。 (继承自 Object)
HasClaim(Predicate<Claim>)	确定该声明标识是否拥有与指定条件相匹配的声明。 (继承自 ClaimsIdentity)
HasClaim(String, String)	确定该声明标识是否具备指定声明类型和值。 (继承自 ClaimsIdentity)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
RemoveClaim(Claim)	尝试从声明标识中移除一个声明。 (继承自 ClaimsIdentity)
RunImpersonated(SafeAccessTokenHandle, Action)	作为模拟 Windows 标识运行指定操作。 可以使用 RunImpersonated(SafeAccessTokenHandle, Action) 并直接作为参数提供函数，而不是使用模拟方法调用并在 WindowsImpersonationContext 中运行函数。
RunImpersonated<T>(SafeAccessTokenHandle, Func<T>)	作为模拟 Windows 标识运行指定函数。 可以使用 RunImpersonated(SafeAccessTokenHandle, Action) 并直接作为参数提供函数，而不是使用模拟方法调用并在 WindowsImpersonationContext 中运行函数。
RunImpersonatedAsync(SafeAccessTokenHandle, Func<Task>)	运行指定异步操作，作为模拟 Windows 标识。
RunImpersonatedAsync<T>(SafeAccessTokenHandle, Func<Task<T>>)	运行指定异步操作，作为模拟 Windows 标识。
ToString()	返回表示当前对象的字符串。 (继承自 Object)
TryRemoveClaim(Claim)	尝试从声明标识中移除一个声明。 (继承自 ClaimsIdentity)
WriteTo(BinaryWriter)	使用 BinaryWriter 序列化。 (继承自 ClaimsIdentity)
WriteTo(BinaryWriter, Byte[])	使用 BinaryWriter 序列化。 (继承自 ClaimsIdentity)

显式接口实现

IDeserializationCallback.OnDeserialization(Object)	实现 ISerializable 接口，并在完成反序列化后由反序列化事件回调。
ISerializable.GetObjectData(SerializationInfo, StreamingContext)	用重新创建此执行上下文的实例所需的逻辑上下文信息设置 SerializationInfo 对象。
