发送端代码如下：

using UnityEngine;

using System.Net;
using System.Net.Sockets;
using System.IO;
using System;

public class SendPhoto : MonoBehaviour
{

    private Socket socket = null;

    private IPEndPoint endPoint = null;

    // Use this for initialization
    void Start()
    {
        InitSocketEnv();
        SendMegEvent();
    }

    // Update is called once per frame
    void Update()
    {

    }

    public void SendMegEvent()
    {
        SendPhotoMessage("haha.jpg");
    }

    void SendPhotoMessage(string fileName)
    {
        //byte[] buffer = ReadImg(fileName); //null

        FileStream fs = new FileStream(Application.dataPath+"/" + fileName, FileMode.OpenOrCreate, FileAccess.Read);
        BinaryReader strread = new BinaryReader(fs);
        byte[] byt = new byte[fs.Length];
        strread.Read(byt, 0, byt.Length - 1);

        //byte[] size = new byte[4];
        //size = BitConverter.GetBytes(byt.Length);

        socket.Send(byt);
        //socket.Send(size);

        fs.Close();
        socket.Close();
    }

    byte[] ReadImg(string fileName)
    {
        FileInfo fileInfo = new FileInfo(Application.dataPath + "/" + fileName);
        byte[] buffer = new byte[fileInfo.Length];
        using (FileStream fs = fileInfo.OpenRead())
        {
            fs.Read(buffer, 0, buffer.Length);
        }

        return buffer;
    }

    void InitSocketEnv()
    {
        socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        endPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8696);
        socket.Connect(endPoint);
    }

    void OnDestory()
    {
