尝试从 <a0/> 同步接收可用输出项。

public:
 virtual bool TryReceive(Predicate<Tuple<System::Collections::Generic::IList<T1> ^, System::Collections::Generic::IList<T2> ^> ^> ^ filter, [Runtime::InteropServices::Out] Tuple<System::Collections::Generic::IList<T1> ^, System::Collections::Generic::IList<T2> ^> ^ % item);
public bool TryReceive(Predicate<Tuple<System.Collections.Generic.IList<T1>,System.Collections.Generic.IList<T2>>> filter, out Tuple<System.Collections.Generic.IList<T1>,System.Collections.Generic.IList<T2>> item);
public bool TryReceive(Predicate<Tuple<System.Collections.Generic.IList<T1>,System.Collections.Generic.IList<T2>>>? filter, out Tuple<System.Collections.Generic.IList<T1>,System.Collections.Generic.IList<T2>>? item);
abstract member TryReceive : Predicate<System.Collections.Generic.IList<'T1> * System.Collections.Generic.IList<'T2>> * Tuple -> bool
override this.TryReceive : Predicate<System.Collections.Generic.IList<'T1> * System.Collections.Generic.IList<'T2>> * Tuple -> bool
Public Function TryReceive (filter As Predicate(Of Tuple(Of IList(Of T1), IList(Of T2))), ByRef item As Tuple(Of IList(Of T1), IList(Of T2))) As Boolean

参数

filter
Predicate<Tuple<IList<T1>,IList<T2>>>

值必须成功传递，才能接收该值。 filter 可以是 null，在这种情况下，所有项都将通过。

item
Tuple<IList<T1>,IList<T2>>

从源接收的项。

返回

Boolean

true 如果可以接收项，则为否则，为 false.

注解

此方法不会阻止等待源提供项。

在检查某个元素后，它将返回该元素是否可用。
