基于消息传输的命名管道：
基于消息的命名管道可以传递不定长的内容，而无需传递内容长度或者结束符，上面非基于消息的传输我们都是在向管道中输入一段文本，使用WriteLine方法以回车换行作为结束符传输信息，而管道的另一端再使用ReadLine方法以读取到回车换行符作为一个消息传递结束的标志；而在使用基于消息传输时就不必这么做了
server端
class Program{
static void Main(string[] args)
{
var running = true;
while (running) // loop only for 1 client
{
PipeSecurity ps = new PipeSecurity();
//获取权限
ps.AddAccessRule(new PipeAccessRule("NETWORK SERVICE", PipeAccessRights.ReadWrite | PipeAccessRights.CreateNewInstance, AccessControlType.Allow));
ps.AddAccessRule(new PipeAccessRule("Users", PipeAccessRights.ReadWrite | PipeAccessRights.CreateNewInstance, AccessControlType.Allow));
ps.AddAccessRule(new PipeAccessRule("CREATOR OWNER", PipeAccessRights.FullControl, AccessControlType.Allow));
ps.AddAccessRule(new PipeAccessRule("SYSTEM", PipeAccessRights.FullControl, AccessControlType.Allow));
//using (var server = new NamedPipeServerStream("PIPE_NAME", PipeDirection.InOut))
using (var server = new NamedPipeServerStream("PIPE_NAME", PipeDirection.InOut, 1, PipeTransmissionMode.Message, PipeOptions.None, 2048, 2048, ps))
{
server.WaitForConnection();
Console.WriteLine("Client connected");
using (var pipe = new PipeStream(server))
{
pipe.Send("handshake");
Console.WriteLine(pipe.Receive());
server.WaitForPipeDrain();
server.Flush();
}
}
}
Console.WriteLine("server closed");
Console.Read();
}
}
