使用TPL.DataFlow块,是否可以将两个或多个源链接到单个ITargetBlock(例如ActionBlock)并确定源的优先级？
例如
BufferBlock<string> b1 = new ...
BufferBlock<string> b2 = new ...
ActionBlock<string> a = new ...
//somehow force messages in b1 to be processed before any message of b2, always
b1.LinkTo (a);
b2.LinkTo (a);
只要b1中有消息,我希望这些消息被输入"a",一旦b1为空,b2消息就被推送到"a"
想法？
