C从套接字读取二进制数据

binary tcp sockets c#

Martijn · 技术社区 · 16 年前

我正在开发一个应用程序,它从套接字读取二进制数据并将其写入套接字。所以首先我用tcpclient创建一个套接字。但我一直在从插座上读取数据。关于如何从套接字中读取二进制数据,是否有任何代码示例?

具体来说,有两件事我不明白。首先,我如何知道消息是否“已接收”?我需要为此创建某种循环吗?第二:什么是读取这些数据的最好方法,因为我接收的数据是二进制的,而不仅仅是普通的字符串。

谢谢

TCPClient documentation

// Get the stream
NetworkStream stream = client.GetStream();
Byte[] data = new Byte[256];

// String to store the response ASCII representation.
String responseData = String.Empty;

// Read the first batch of the TcpServer response bytes.
int bytes = stream.Read(data, 0, data.Length);
responseData = System.Text.Encoding.ASCII.GetString(data, 0, bytes);

TcpClients TcpListeners serialization

NetworkStream stream = client.GetStream();

public void send(NetworkStream stream, byte[] buf) {
    stream.Write(BitConverter.GetBytes(buf.Length), 0, 4);
    stream.Write(buf, 0, buf.Length);
}

public byte[] receive(NetworkStream stream) {
    byte[] lengthBytes = new byte[4];
    int read = stream.Read(lengthBytes, 0, 4);
    // read contains the number of read bytes, so we can check it if we want
    int length = BitConverter.GetInt32(lengthBytes);
    byte[] buf = new byte[length];
    stream.Read(buf, 0, buf.length);
    return buf;
}
