所以,我试图在服务器和客户端之间发送图像,但是,当服务器收到图像时,图像不会呈现所有图像。
客户端代码:
//button click
Bitmap tImage = new Bitmap(@"C:\Users\Milan\Downloads\guitarstill.gif");
byte[] bStream;
//if (string.IsNullOrEmpty(tbPayload.Text)) return;
try
{
bStream = imageToByteArray(tImage);
if (mTcpClient != null)
{
if (mTcpClient.Client.Connected)
{
mTcpClient.GetStream().BeginWrite(imageToByteArray(tImage), 0, imageToByteArray(tImage).Length, onCompleteWriteToServer, mTcpClient);
}
}
}
catch (Exception exc)
{
MessageBox.Show(exc.Message);
}
//Within another method:
public byte[] imageToByteArray(System.Drawing.Image imageIn) {
MemoryStream ms = new MemoryStream();
imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);
//richTextBox1.Text = ms.ToArray().ToString();
return ms.ToArray();
}
服务器端代码:
void onCompleteReadFromTCPClientStream(IAsyncResult iar)
{
TcpClient tcpc;
int nCountReadBytes = 0;
string strRecv;
ClientNode cn = null;
try
{
lock (mlClientSocks)
{
tcpc = (TcpClient)iar.AsyncState;
cn = mlClientSocks.Find(x => x.strId == tcpc.Client.RemoteEndPoint.ToString());
nCountReadBytes = tcpc.GetStream().EndRead(iar);
if (nCountReadBytes == 0)// this happens when the client is disconnected
{
MessageBox.Show("Client disconnected.");
mlClientSocks.Remove(cn);
lbClients.Items.Remove(cn.ToString());
return;
}
strRecv = Encoding.ASCII.GetString(cn.Rx, 0, nCountReadBytes);
//strRecv = Encoding.ASCII.GetString(mRx, 0, nCountReadBytes);
if (strRecv.StartsWith("GIF"))
{
//MemoryStream ms = new MemoryStream(cn.Rx);
//Image x = (Bitmap)((new ImageConverter()).ConvertFrom(cn.Rx));
pictureBox1.Image = byteArrayToImage(cn.Rx);
/*
lock (mlClientSocks)
{
//if (cn != null && cn.tclient != null && cn.tclient.Client.Connected)
//{
//foreach (var clients in spectatorsIPAndPort)
//{
cn = mlClientSocks.Find(x => x.strId == clients);
cn.Tx = new byte[512];
cn.Tx = Encoding.ASCII.GetBytes(strRecv);
cn.tclient.GetStream().BeginWrite(cn.Tx, 0, cn.Tx.Length, onCompleteWriteToClientStream, cn.tclient);
//Console.WriteLine("Sent Number of Clients via Request: " + Encoding.UTF8.GetString(cn.Tx) + " To " + clients);
//}
//}
}
*/
//printLine(DateTime.Now + " - " + cn.ToString() + ": " + strRecv);
}
cn.Rx = new byte[512];
tcpc.GetStream().BeginRead(cn.Rx, 0, cn.Rx.Length, onCompleteReadFromTCPClientStream, tcpc);
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
lock (mlClientSocks)
{
printLine("Client disconnected: " + cn.ToString());
mlClientSocks.Remove(cn);
lbClients.Items.Remove(cn.ToString());
}
}
}
//within another method
public Image byteArrayToImage(byte[] byteArrayIn)
{
MemoryStream ms = new MemoryStream(byteArrayIn, 0, byteArrayIn.Length);
//ms.Position = 0;
Image returnImage = Image.FromStream(ms);
return returnImage;
}
我的输出:
预期输出: - 此完整图像
