Are there any cases when TcpClient.Close or Socket.Close(0) could block my code?

问题 As it's not specified that Close method is thread safe I should call it from the lock. How can I be sure that it will not block my thread? Should I disable LingerState or can it be enabled? btw do I need to call both TcpClient.Close and TcpClient.Client.Close? 回答1: According to the documentation for TcpClient.Close, calling this method disposes the instance. A quick look in ILSpy reveals that it simply calls Dispose , which calls Dispose(true) . Furthermore, the documentation states that

I've been searching for code to do this and haven't found any luck, i've seen lots of code samples online that don't work. please if any of you can solve this problem I would be very

问题 Storyline: I wanted to make my very own webserver in c#(first attempt).

As I was trying to add SSL support to it I encountered a problem. I have been trying to authenticate as a TcpServer with SSL support using SSLStream.AuthenticateAsServer([self-signed certificate]) for the last 7 days Problem: As I get the [Upgrade-Insecure-Requests: 1] from my

Cancel C# 4.5 TcpClient ReadAsync by timeout

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-07 04:47:01
问题 What would the proper way to cancel TcpClient ReadAsync operation by timeout and catch this timeout event in .NET 4.5? TcpClient.ReadTimeout seems to be applied to the sync Read only. UPDATE: Tried tro apply the approach desribed here Cancelling an Asynchronous Operation var buffer = new byte[4096]; CancellationTokenSource cts = new CancellationTokenSource(5000); int amountRead = await tcpClientStream.ReadAsync(buffer, 0, 4096, cts.Token); but it never cancels by timeout. Is anything wrong?
