程序間通信包括:有名管道,無名管道,信号量,消息隊列,共享記憶體以及socket。
有名管道可以用于任意程序間的通信,而無名管道必須是有血緣關系程序間的通信。
1.服務端
using System;
using System.Collections.Generic;
using System.IO;
using System.IO.Pipes;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace PipeServer
{
class Program
{
static void Main(string[] args)
{
WaitData();
}
private static void WaitData()
{
using (NamedPipeServerStream pipeserver = new NamedPipeServerStream("TestPipe", PipeDirection.InOut, 5))
{
try
{
Console.WriteLine("Wait Connect");
pipeserver.WaitForConnection();//等待用戶端連接配接
pipeserver.ReadMode = PipeTransmissionMode.Byte;//讀取模式為位元組
Console.WriteLine("success connected?"+pipeserver.IsConnected.ToString());
StreamReader sr = new StreamReader(pipeserver);//擷取管道輸入流
StreamWriter sw = new StreamWriter(pipeserver);//擷取管道輸出流
string result = string.Empty;
while (true)
{
result = sr.ReadLine();
if (result == null || result == "bye")
{
break;
}
else
{
Console.WriteLine(result);
sw.WriteLine("I am Server.");//發送給用戶端
sw.Flush();//清空緩存以免管道阻塞
}
}
Console.ReadKey();
}
catch (IOException ee)
{
throw ee;
}
}
}
}
}

2.用戶端
using System;
using System.Collections.Generic;
using System.IO;
using System.IO.Pipes;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace PipClient
{
class Program
{
static void Main(string[] args)
{
StartClient();
Console.ReadKey();
}
private static void StartClient()
{
string input = string.Empty;
try
{
using (NamedPipeClientStream pipeStream = new NamedPipeClientStream("localhost", "TestPipe"))
{
pipeStream.Connect();//連接配接服務端
if (!pipeStream.IsConnected)
{
Console.WriteLine("Failed to connect ....");
return;
}
StreamWriter sw = new StreamWriter(pipeStream);//擷取管道輸出流
StreamReader sr = new StreamReader(pipeStream);//擷取管道輸入流
while (true)
{
input = Console.ReadLine();
Console.WriteLine("SendMessage"+input);
sw.WriteLine(input);//發送消息給服務端
sw.Flush();//清空緩存
string temp = string.Empty;
temp = sr.ReadLine();//擷取服務端響應的消息
Console.WriteLine("reply Content:"+temp);
}
}
}
catch (IOException ee)
{
Console.WriteLine(ee.Message.ToString()+"\n"+ee.StackTrace.ToString());
throw ee;
}
}
}
}
