我正在尝试使用 C# 套接字发送图像。它有效,但不稳定。通过发送的图像非常大,并且更新非常快,这导致它不时闪烁。如果可能的话,我正在寻找一种压缩发送的数据的方法。我正在使用这段代码:
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);
}
