我正在尝试使用C#套接字发送图像。它有效,但它不稳定。发送的图像非常大,并且很快更新,导致它偶尔闪烁。我正在寻找一种压缩所发送数据的方法。我正在使用此代码:
服务器端:
System.IO.MemoryStream stream = new System.IO.MemoryStream();
// !! Code here that captures the screen !!
bitmap.Save(stream, myImageCodecInfo, myEncoderParameters);
byte[] imageBytes = stream.ToArray();
stream.Dispose();
// Send the image
clientSocket.Send(imageBytes);
// Empty the byte array?
for (int i = 0; i < imageBytes.Length; i++)
{
imageBytes[i] = 0;
}
客户端:
private void OnConnect(IAsyncResult ar)
{
try
{
MessageBox.Show("Connected");
//Start listening to the data asynchronously
clientSocket.BeginReceive(byteData,
0,
byteData.Length,
SocketFlags.None,
new AsyncCallback(OnReceive),
null);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Stream Error",MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
private void OnReceive(IAsyncResult ar)
{
try
{
int byteCount = clientSocket.EndReceive(ar);
// Display the image on the pictureBox
MemoryStream ms = new MemoryStream(byteData);
pictureBox1.Image = Image.FromStream(ms);
}
catch (ArgumentException e)
{
//MessageBox.Show(e.Message);
}
clientSocket.BeginReceive(byteData,0,byteData.Length,SocketFlags.None,new AsyncCallback(OnReceive),null);
}
答案 0 :(得分:0)
我最终使用gzip。
原来闪烁不是因为它很快更新,而是因为我设置套接字的方式。它没有发送整个图像。
