C＃客户端/服务器：使用Streamreader / writer [英] C# Client/Server: using Streamreader/writer

问题描述

我对C＃来说还比较陌生，但这里有：

I'm relatively new to C# but here goes:

我正在C＃中开发一个远程文件服务客户端/服务器控制台应用程序，该应用程序应该使用同步插座。

I am developing a remote file service client/server console application in C# which is supposed to exchange messages using synchronous sockets.

主要问题之一（甚至认为它看起来似乎很简单）是使用streamreader / streamwriter从服务器向客户端返回一个字符串。

One of the main problems (even thought it might seem simple) is to return a string from the server, to the client using streamreader/streamwriter.

应用程序用户是一个命令行界面，带有用于执行操作的选项（来自switch语句）。即键入1并输入enter将执行代码，以将字符串从服务器发送到客户端。

The application user a command line interface with options (from a switch statement) to execute actions. I.e. typing 1 and enter would execute the code to send the string from the server to the client.

下面是客户端的示例代码：

Below is a sample code from the client:

        try
        {
            using (TcpClient client = (TcpClient)clientObject)
            using (NetworkStream stream = client.GetStream())
            using (StreamReader rd = new StreamReader(stream))
            using (StreamWriter wr = new StreamWriter(stream))
            {

                string menuOption = rd.ReadLine();


                switch (menuOption)
                    {
                        case "1":
                        case "one":
                            string passToClient = "Test Message!";
                            wr.WriteLine(passToClient);
                            break;
                   } 
                      while (menuOption != "4");
               }
         }

我了解我发布的代码只是其中的一小段该程序，但它会占用相当多的空间，希望您能从中了解我的意思，否则，我会发布更多内容。

I understand the code I posted is just a snippet of the program, but it would take up a fair amount of space and was hoping you can gather what I mean from this, if not I will post more.

这仅仅是

感谢您提供的任何帮助/建议。它不是我正在寻找的代码示例（尽管有一些帮助），但是关于流阅读器/写入器的更多解释是因为我似乎无法理解很多在线内容。

I appreciate any help / advice you can give. Its not so much code examples I'm looking for (although a little would help) but more some explanation on streamreader/writer as I cant seem to understand much of what is online.

谢谢。

推荐答案

我认为您只是想念一个 wr.flush（）;。 ，但本文应涵盖您需要的所有内容：

I think you're just missing a wr.flush(); but this article should cover everything you need:
