我想将图像从服务器发送到客户端 [英] I want to send image from server to client

问题描述

我正在尝试将图像从服务器发送到客户端。服务器发送了图像，但客户端没有显示它..我的代码有问题。

有人可以帮我吗。



我尝试过：



server \\

 private void button6_Click（object sender，EventArgs e）
 {
 try 
 {
 Image img = Image.FromFile（D：\\\\ .jpg）; 
 MemoryStream ms = new MemoryStream（）; 
 img.Save（ms，System.Drawing.Imaging.ImageFormat.Jpeg）; 
 bytes = ms.ToArray（）; 
 acc.Send（bytes，0，bytes.Length，0）; 
 MessageBox.Show（ok）; 
} 
 catch 
 {
 MessageBox.Show（Failure ....）; 
} 
 
} 

client \\

试试
 {
 sock.Connect（new IPEndPoint（IPAddress.Parse（textBox3.Text），3））; 
 
 new Thread（（）=> 
 {
 read（）; 
}）。Start（）; 
 
 
} 
 catch 
 {
 MessageBox.Show（failure）; 
} 
 
 
} 
 
 void read（）
 {
而（true）
 {
 try 
 {
 
 byte [] buffer = new byte [255]; 
 int rec = sock.Receive（buffer，0，buffer.Length，0）; 
 if（rec< = 0）
 {
抛出新的SocketException（）; 
} 
 Array.Resize（ref buffer，rec）; 
 Invoke（（MethodInvoker）委托
 {
 
 MemoryStream imgstream = new MemoryStream（buffer）; 
 Image imgfromstream = Image.FromStream（imgstream）; 
 pictureBox1.Image = imgfromstream; 
 
 
}）; 
 
} 
 catch 
 {
 MessageBox.Show（Disconcting）; 
 sock.Close（）; 
休息; 
} 
 
} 
 Application.Exit（）; 
}

                    byte[] buffer = new byte[255];
                    int rec = sock.Receive(buffer, 0, buffer.Length, 0);
                    if (rec <= 0)
                    {
                        throw new SocketException();
                    }
                    Array.Resize(ref buffer, rec);
                    Invoke((MethodInvoker)delegate
                    {
                        
                        MemoryStream imgstream = new MemoryStream(buffer);
