Source: PipeStream.cs 获取一个值,该值指示 PipeStream 对象是异步打开还是同步打开。 C# 复制 public bool IsAsync { get; } 属性值 Boolean 如果PipeStream 对象是异步打开的,则为 true;否则为 false。 注解 此属性使代码能够正确使用 SafePipeHandle 属性。 适用于 产品版本 .NET Core 1.0, Core 1.1...

其实pipe针对Readable和Writeable做了限流,首先针对Readable的data事件进行侦听,并执行Writeable的write函数,当Writeable的写缓冲区大于一个临界值(highWaterMark),导致write函数返回false(此时意味着Writeable无法匹配Readable的速度,Writeable的写缓冲区已经满了),此时,pipe修改了Readable模式,执行pause方法,进入paused模式,停止...
