重要

此 API 不符合 CLS。

返回用户提供的对象，该对象在通过调用 AllocateNativeOverlapped(IOCompletionCallback, Object, Object) 方法分配 NativeOverlapped 实例时指定。

public:
 static System::Object ^ GetNativeOverlappedState(System::Threading::NativeOverlapped* overlapped);

[System.CLSCompliant(false)]
public static object GetNativeOverlappedState (System.Threading.NativeOverlapped* overlapped);

[System.CLSCompliant(false)]
public static object? GetNativeOverlappedState (System.Threading.NativeOverlapped* overlapped);

[System.CLSCompliant(false)]
[System.Security.SecurityCritical]
public static object GetNativeOverlappedState (System.Threading.NativeOverlapped* overlapped);

[<System.CLSCompliant(false)>]
static member GetNativeOverlappedState : nativeptr<System.Threading.NativeOverlapped> -> obj

[<System.CLSCompliant(false)>]
[<System.Security.SecurityCritical>]
static member GetNativeOverlappedState : nativeptr<System.Threading.NativeOverlapped> -> obj

参数

overlapped

NativeOverlapped*

指向 NativeOverlapped 结构的非托管指针，将从该结构中返回用户提供的关联对象。

返回

Object

用户提供的对象，用于区分此 NativeOverlapped 实例与其他 NativeOverlapped 实例，或者，如果在通过调用 AllocateNativeOverlapped 方法分配实例时未进行指定，则为 null。

属性

CLSCompliantAttribute SecurityCriticalAttribute

例外

ArgumentNullException

overlapped 为 null。
