我有两个基本的控制台应用程序,即使所有通信都在我的本地计算机上进行,也可以通过“网络”进行通信。
客户代码:
public static void Main()
{
while (true)
{
try
{
TcpClient client = new TcpClient();
client.Connect("127.0.0.1", 500);
Console.WriteLine("Connected.");
byte[] data = ASCIIEncoding.ASCII.GetBytes(new FeederRequest("test", TableType.Event).GetXmlRequest().ToString());
Console.WriteLine("Sending data.....");
using (var stream = client.GetStream())
{
stream.Write(data, 0, data.Length);
stream.Flush();
Console.WriteLine("Data sent.");
}
client.Close();
Console.ReadLine();
}
catch (Exception e)
{
Console.WriteLine("Error: " + e.StackTrace);
Console.ReadLine();
}
}
}
服务器代码:
public static void Main()
{
try
{
IPAddress ipAddress = IPAddress.Parse("127.0.0.1");
Console.WriteLine("Starting TCP listener...");
TcpListener listener = new TcpListener(ipAddress, 500);
listener.Start();
Console.WriteLine("Server is listening on " + listener.LocalEndpoint);
while (true)
{
Socket client = listener.AcceptSocket();
Console.WriteLine("\nConnection accepted.");
var childSocketThread = new Thread(() =>
{
Console.WriteLine("Reading data...\n");
byte[] data = new byte[100];
int size = client.Receive(data);
Console.WriteLine("Recieved data: ");
for (int i = 0; i < size; i++)
Console.Write(Convert.ToChar(data[i]));
//respond to client
Console.WriteLine("\n");
client.Close();
Console.WriteLine("Waiting for a connection...");
});
childSocketThread.Start();
}
}
catch (Exception e)
{
Console.WriteLine("Error: " + e.StackTrace);
Console.ReadLine();
}
}
如何更改这两个应用程序,以便服务器收到数据后以某种确认的方式响应客户端?
提前致谢!
最佳答案
这里有一个简短的例子,我将如何做:
服务器:
class Server
{
static void Main(string[] args)
{
TcpListener listener = new TcpListener(IPAddress.Any, 1500);
listener.Start();
TcpClient client = listener.AcceptTcpClient();
NetworkStream stream = client.GetStream();
// Create BinaryWriter for writing to stream
BinaryWriter binaryWriter = new BinaryWriter(stream);
// Creating BinaryReader for reading the stream
BinaryReader binaryReader = new BinaryReader(stream);
while (true)
{
// Read incoming information
byte[] data = new byte[16];
int receivedDataLength = binaryReader.Read(data, 0, data.Length);
string stringData = Encoding.ASCII.GetString(data, 0, receivedDataLength);
// Write incoming information to console
Console.WriteLine("Client: " + stringData);
// Respond to client
byte[] respondData = Encoding.ASCII.GetBytes("respond");
Array.Resize(ref respondData, 16); // Resizing to 16 byte, because in this example all messages have 16 byte to make it easier to understand.
binaryWriter.Write(respondData, 0, 16);
}
}
}
客户:
class Client
{
private static void Main(string[] args)
{
Console.WriteLine("Press any key to start Client");
while (! Console.KeyAvailable)
{
}
TcpClient client = new TcpClient();
client.Connect("127.0.0.1", 1500);
NetworkStream networkStream = client.GetStream();
// Create BinaryWriter for writing to stream
BinaryWriter binaryWriter = new BinaryWriter(networkStream);
// Creating BinaryReader for reading the stream
BinaryReader binaryReader = new BinaryReader(networkStream);
// Writing "test" to stream
byte[] writeData = Encoding.ASCII.GetBytes("test");
Array.Resize(ref writeData, 16); // Resizing to 16 byte, because in this example all messages have 16 byte to make it easier to understand.
binaryWriter.Write(writeData, 0, 16);
// Reading response and writing it to console
byte[] responeBytes = new byte[16];
binaryReader.Read(responeBytes, 0, 16);
string response = Encoding.ASCII.GetString(responeBytes);
Console.WriteLine("Server: " + response);
while (true)
{
}
}
}
我希望这有帮助! ;)
关于c# - 使用套接字响应客户端?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/19388352/
