Unity sends game screen to Winform

First, take a look at the Unity interface:

Set up 2 cameras, position overlap, rotate the same, parent-child relationship, add script A.cs to the parent camera, and copy the sub-camera to the variable cam in the a script;

Cam is used to provide the screen for the Rendertexture, port is the socket listening ports;

Second, the A.cs script code (night too deep, another day to add comments, direct sticker code)

usingSystem;usingSystem.Collections;usingSystem.Collections.Generic;usingSystem.Net;usingSystem.Net.Sockets;usingSystem.Threading;usingUnityengine; Public classa:monobehaviour{ PublicCamera Cam;  Public intPort =10002; Rendertexture Cameraview=NULL; Socket Socket=NULL; Thread Thread=NULL; BOOLSuccess =true; /// <summary>    ///Client List/// </summary>dictionary<string, client> clients =Newdictionary<string, client>(); Vector3 old_position;//Old LocationQuaternion old_rotation;//Old Rotation    voidStart () {Cameraview=NewRendertexture (Screen.width, Screen.height, -); Cameraview.enablerandomwrite=true; Cam.targettexture=Cameraview; Old_position=transform.position; Old_rotation=transform.rotation; Socket=Newsockets (AddressFamily.InterNetwork, SocketType.Stream, protocoltype.tcp); Socket.

ThreadState = =threadstate.running) {Socket _socket=socket.            Accept (); if(clients. ContainsKey (_socket. Remoteendpoint.tostring ())) {Try{clients[_socket. Remoteendpoint.tostring ()].socket.                Shutdown (Socketshutdown.both); }                Catch{} clients. Remove (_socket.            Remoteendpoint.tostring ()); } Client Client=NewClient {Socket=_socket}; Clients. ADD (_socket.            Remoteendpoint.tostring (), client); Isnewadd=1; Debug.logerror ("Connect ..."); }    }    voidUpdate () {if(Success && clients. Count >0) {Success=false;        Sendtexture (); }        if(Isnewadd >0) {Isnewadd=0; Sendtexture (1); }    }    voidOngui () {GUI.

Values) {Try{val.socket.Send (bytes); }                Catch                {                    if(!val.socket.Connected) clients.                    Remove (Val.socket.RemoteEndPoint.ToString ());  Break; }} Gc_count++; if(Gc_count > the) {Gc_count=0; Gc. Collect (2); } Debug.Log ("Send data:"+ (float) bytes. length/1024f +"KB"); Old_position=transform.position; Old_rotation=transform.rotation; } Success=true; }}classclient{ PublicSocket socket =NULL;}

Third, WinForm end

Drag a PictureBox directly onto the window to dock the parent form;

Iv. WinForm Code

usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.IO;usingSystem.Linq;usingSystem.Net;usingSystem.Net.Sockets;usingSystem.Text;usingSystem.Threading;usingSystem.Threading.Tasks;usingSystem.Windows.Forms;namespacetransformviewclient{ Public Partial classForm1:form {BOOLIsover =false; Socket Socket=NULL; Thread Thread=NULL; byte[] buffer =NULL; BOOLRecestate =true; intReadtimes =0;  PublicForm1 () {InitializeComponent (); }        Private voidForm1_Load (Objectsender, EventArgs e) {Control.checkforillegalcrossthreadcalls=true; Buffer=New byte[1024x768*1024x768*Ten]; Socket=Newsockets (AddressFamily.InterNetwork, SocketType.Stream, protocoltype.tcp); Socket. Connect (Ipaddress.parse ("127.0.0.1"),10002); Thread=NewThread (NewThreadStart (Receive)); Thread.        Start (); }        voidReceive () { while(Thread. ThreadState = = Threadstate.running &&socket. Connected) {intCount =socket.                Receive (buffer); if(Recestate && Count >0) {recestate=false;                Bytestoimage (count, buffer); }}} MemoryStream ms=NULL;  Public voidBytestoimage (intCountbyte[] bytes) {            Try{ms=NewMemoryStream (Bytes,0, Count); pictureBox1.Image=Image.fromstream (MS); Readtimes++; if(Readtimes > the) {Readtimes=0; Gc. Collect (2); }            }            Catch{} recestate=true; }        Private voidForm1_formclosing (Objectsender, FormClosingEventArgs e) {            Try{socket.            Shutdown (Socketshutdown.both); }            Catch { }            Try{thread.            Abort (); }            Catch { }        }    }}

There may be many bugs and flaws in the program, I hope the expert guidance!
