我正在寻找一个很好的示例,其中NamedPipeServerStream和NamedPipeServerClient可以相互发送消息(当PipeDirection = PipeDirection.InOut时)。目前我只找到了这篇msdn文章。但它仅描述了服务器。有人知道连接到此服务器的客户端应该是什么样子吗?
服务器会一直等待连接,当它接收到一个连接请求后,会发送一个简单的握手字符串“Waiting”,客户端会读取并测试该字符串,然后发送一个字符串“Test Message”(在我的应用程序中实际上是命令行参数)。
请记住,WaitForConnection
是阻塞的,因此您可能希望在单独的线程上运行它。
class NamedPipeExample
{
private void client() {
var pipeClient = new NamedPipeClientStream(".",
"testpipe", PipeDirection.InOut, PipeOptions.None);
if (pipeClient.IsConnected != true) { pipeClient.Connect(); }
StreamReader sr = new StreamReader(pipeClient);
StreamWriter sw = new StreamWriter(pipeClient);
string temp;
temp = sr.ReadLine();
if (temp == "Waiting") {
try {
sw.WriteLine("Test Message");
sw.Flush();
pipeClient.Close();
}
catch (Exception ex) { throw ex; }
}
}
同类,服务器方法
private void server() {
var pipeServer = new NamedPipeServerStream("testpipe", PipeDirection.InOut, 4);
StreamReader sr = new StreamReader(pipeServer);
StreamWriter sw = new StreamWriter(pipeServer);
do {
try {
pipeServer.WaitForConnection();
string test;
sw.WriteLine("Waiting");
sw.Flush();
pipeServer.WaitForPipeDrain();
test = sr.ReadLine();
Console.WriteLine(test);
}
catch (Exception ex) { throw ex; }
finally {
pipeServer.WaitForPipeDrain();
if (pipeServer.IsConnected) { pipeServer.Disconnect(); }
}
} while (true);
}
}
