c# - 同时从多个线程在 NetworkStream 上使用 WriteAsync 是否线程安全？

Question

当有一个 TcpClient 在多个线程中获取其 stream 并在每个线程上对其执行 WriteAsync 时。它是线程安全的吗？数据(传递给 write 方法的字节数组)是否会作为传递给 WriteAsync

的完整 block 传送

Answer 1

不，这不安全。

来自MSDN under Remarks :

Read and write operations can be performed simultaneously on an instance of the NetworkStream class without the need for synchronization. As long as there is one unique thread for the write operations and one unique thread for the read operations, there will be no cross-interference between read and write threads and no synchronization is required.

因此，当您有多个写入线程时，您需要同步它们。
