使用tcpclient c＃将客户端的桌面映像发送到服务器。 [英] Sending desktop images of the client to server using tcpclient c#.

问题描述

大家好，我有一个项目需要将客户端的桌面映像发送到服务器。服务器必须处理所有传入连接，并且每个客户端都会出现一个新的窗体，其中包含一个图片框，而此图片框包含该客户端的图像。请帮帮我......提前致谢。



我尝试过的事情：



我已经尝试过搜索这个问题，但大多数解决方案都使用服务器和客户端之间的同步通信。

解决方案

我发布了客户端代码示例。它可能会有用。

流imageFileStream = File.OpenRead（  YourFullFilePath）; 
  byte  [] byteArray =  new   byte [imageFileStream.Length]; 
 imageFileStream.Read（byteArray， 0 ，（ int ）imageFileStream.Length）; 
 TcpClient client =  new  TcpClient（  YourServer ， 8080 ）;  //   8080是运行服务器的端口。 
 NetworkStream network = client.GetStream（ ）; 
 network.Write（byteArray， 0 ，byteArray.GetLength（ 0 ））; 
 network.Close（）; 

嗨！希望你通过我的例子得到想法。在这里我给你服务器端示例。

服务器端代码可以是：

 TcpListener ServerforTCP =  new  TcpListener（ 8080 ）; 
 ServerforTCP.Start（）; 
  while （ true ）
 {
 Socket socketToHandleRequest = ServerforTCP。 AcceptSocket（）;  //  接受客户请求。 
 NetworkStream network =  new  NetworkStream（socketToHandleRequest）; 
 
  int  readPoint =  0 ; 
  int  chunkSize =  1024 ; 
  byte  [] data =  new   byte < /跨度> [CHUNKSIZE]; 
  lock （此） //  处理多个客户端调用问题 
 {
流fileForWrite = File.OpenWrite（  FilePathWithFileNameWhereYouWantTosaveYourJPGFILE）;  //   ex：D ：\\File.jpg  
  while （ true ）
 {
 readPoint = network.Read（data， 0 ，chunkSize）; 
 fileForWrite.Write（data， 0 ，readPoint）; 
  if （readPoint ==  0 ）
 {
  //  从客户端读取的文件的结尾。你可以打破循环。 
  break ; 
} 
} 
 fileForWrite.Close（）;  //  必须关闭。 
} 
 socketToHandleRequest = 空;  //  指定null以释放记忆。 
 System.Threading.Thread.Sleep（ 1000 ）; 
} 
 

谢谢！。

嗨！这是我的第一个答案，所以请帮助我更好地回答我的答案。我只是试着简单地表达一下。



你试试过流吗？

总之我想问你有没有尝试将你的图像文件流读入byte [] 并将该文件发送到服务器？

相同，你可以在服务器端以相反的顺序执行此操作。

得到 byte []并保存带有图像文件扩展名的字节[] 。 />


你试过这个吗？如果没有，请告诉我，我会在这里发布演示。

谢谢。

Hi everyone, I have a project that requires sending desktop images of the client to the server. The server must handle all incoming connection and to every client, a new windows form will appear that has a picture box in it whereas this picture box contain the images of that client. Please help me... Thanks in advance.

What I have tried:

I already tried searching to this problem, but most solution uses a synchronous communication between server and client.

解决方案

I posted Client Side Code For an Example. may it would be useful.

Stream imageFileStream = File.OpenRead("YourFullFilePath");
           byte[] byteArray=new byte[imageFileStream.Length];
           imageFileStream.Read(byteArray, 0, (int)imageFileStream.Length);
           TcpClient client = new TcpClient("YourServer",8080); //8080 is the port where server is running.
           NetworkStream network = client.GetStream();
           network.Write(byteArray,0,byteArray.GetLength(0));
           network.Close();

Hi! hope you getting idea by my example. here I am giving you server side example.
Server side code can be like :

TcpListener ServerforTCP = new TcpListener(8080);
           ServerforTCP.Start();
           while (true)
           {
               Socket socketToHandleRequest = ServerforTCP.AcceptSocket(); //accept client request.
               NetworkStream network = new NetworkStream(socketToHandleRequest);

               int readPoint = 0;
               int chunkSize = 1024;
               byte[] data=new byte[chunkSize];
               lock (this) //to handle multiple client call issue
               {
                   Stream fileForWrite = File.OpenWrite("FilePathWithFileNameWhereYouWantTosaveYourJPGFILE");// ex :D:\\File.jpg
                   while (true)
                   {
                       readPoint = network.Read(data, 0, chunkSize);
                       fileForWrite.Write(data,0,readPoint);
                       if(readPoint==0)
                       {
                           //end of the file read from client. you can break the loop.
                           break;
                       }
                   }
                   fileForWrite.Close(); // Must Close.
               }
               socketToHandleRequest = null; // assign null to release memeory.
               System.Threading.Thread.Sleep(1000);
           }

Thanks!.

Hi! this is my first answer so please help to make my answer skill better. I just try to express things in brief.

Have you try with stream ?
in short I want to ask you that have you try to read stream of your image file into byte[] and send that file to server?
same you can do this in reverse order at Server side.
get byte[] and save that byte[] with image file extension.

have you tried this? if not then let me know I will post demo here.
Thanks.
