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)。现在我只发现了this msdn article。但它只描述了服务器。有人知道客户端连接到这个服务器的样子应该是什么样的吗?
答案 0 :(得分:35)
服务器正在等待连接,当它有一个发送字符串“Waiting”作为简单握手时,客户端然后读取它并测试它然后发回一串“测试消息”(在我的应用程序实际上是命令行args)。
请记住,WaitForConnection
正在阻止,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; }
}
}
同一类,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);
}
}
