我想创建一个通过网络传输多个图像的项目。我只是想从小的功能性代码开始,但对我来说已经遇到了一个时髦的问题。图像已收到,但它包含图形错误,例如它的一部分。
可悲的是无法显示图像导致低信誉,这里是链接。 http://img543.imageshack.us/img543/1508/buggedy.jpg
当然,百万美元的答案。^^
TcpListener listener;
TcpClient client;
TcpClient datatoclient;
NetworkStream stream;
主机部分:
listener = new TcpListener(5000);
listener.Start();
datatoclient = listener.AcceptTcpClient();
NetworkStream nowystream = datatoclient.GetStream();
MemoryStream ms = new MemoryStream();
byte[] image = File.ReadAllBytes("default.jpg");
switch (trackBar1.Value)
{
case 0:
image = File.ReadAllBytes("mirrion.jpg");
break;
case 1:
image = File.ReadAllBytes("tenis.jpg");
break;
case 2:
image = File.ReadAllBytes("marisasold.jpg");
break;
}
// get the image size in bytes
int numberOfBytes = image.Length;
// put the size into an array
byte[] numberOfBytesArray = BitConverter.GetBytes(numberOfBytes);
// send the image size
nowystream.Write(numberOfBytesArray, 0, numberOfBytesArray.Length);
// send the image
nowystream.Write(image, 0, numberOfBytes);
客户端部分:
client = new TcpClient("127.0.0.1", 5000);
stream = client.GetStream();
byte[] data = new byte[4];
// read the size
stream.Read(data, 0, data.Length);
int size = BitConverter.ToInt32(data, 0);
label1.Text = size.ToString();
// prepare buffer
data = new byte[size];
// load image
stream.Read(data, 0, data.Length);
// save image to file for test
File.WriteAllBytes("received.jpg", data);
MemoryStream MS = new MemoryStream(data);
pictureBox1.Image = Image.FromStream(MS);
