Question

In my java application I want to transfer some Images from client to server.
I am using Socket to connect client with server.
It is working when I transfer string from client to server but I am not able to transfer Image file.

I am using

BufferedInputStream
BufferedOutputStream

for transferring string.

I know for transferring file I need to use FileInputStream as:

BufferedInputStream bis bis = new BufferedInputStream(new FileInputStream("111.JPG"));

But I don’t know, what exactly I need to write.
so please give your answer by some sample of code.

Answer 1

You should convert image to byte.
You can use this function.

static byte[] ImageToByte(System.Drawing.Image iImage)
{
MemoryStream mMemoryStream = new MemoryStream();
iImage.Save(mMemoryStream,
System.Drawing.Imaging.ImageFormat.Gif);
return mMemoryStream.ToArray();
}

And you can call this function in your server program.

Bitmap tImage = new Bitmap(Image URL goes here);
byte[] bStream = ImageToByte(tImage);

while (true)
{
TcpClient client = server.AcceptTcpClient();
Console.WriteLine("Connected");
while (client.Connected)
{
NetworkStream nStream = client.GetStream();
nStream.Write(bStream, 0,
bStream.Length);
}
}
