Question

我已经创建了一个通过TCP套接字发送图像的程序，它可以运行一段时间然后总是在服务器端反序列化流错误。

Additional information: Binary stream '0' does not contain a valid BinaryHeader. Possible causes are invalid stream or object version change between serialization and deserialization.

导致错误的完整功能是：

private void handleClientThread(TcpClient tcpClient)
{
    while (true)
    {
        BinaryFormatter binaryFormatter = new BinaryFormatter();
        pictureBox1.Image = (Image)binaryFormatter.Deserialize(tcpClient.GetStream()); // this line is the one throwing an exception
        pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
    }

}

客户端正在正确发送所有内容：

private Image TakePicture()
{
    Bitmap bmpScreenCapture = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
    Graphics g = Graphics.FromImage(bmpScreenCapture);
    g.CopyFromScreen(Screen.PrimaryScreen.Bounds.X, Screen.PrimaryScreen.Bounds.Y, 0, 0, bmpScreenCapture.Size, CopyPixelOperation.SourceCopy);

    return bmpScreenCapture;
}

private void SendPicture()
{
    Image clientPicture = TakePicture();

    BinaryFormatter binaryFormatter = new BinaryFormatter();
    binaryFormatter.Serialize(sharerClient.GetStream(), clientPicture);
}

任何人都可以帮我解决这个问题，或者帮助我通过TCP套接字发送图像而不会抛出异常。

Answer 1

private void SendPicture()
{
    Image clientPicture = TakePicture();
    clientPicture.Save(sharerClient.GetStream(), ImageFormat.Png);
}

我想出了Lucas Trzesniewski，但我如何在服务器端做到这一点？

C＃ - 图像 - 二进制格式化程序反序列化错误 - 不包含有效的BinaryHeader
