Question

我有两个不同的可执行文件在同一台运行Windows OS的计算机上运行。它们都是在Unity中构建的。我想将消息从一个发送到其他而不使用网络。

如何从exe程序向Unity中的另一个exe程序发送消息？

这可能与integrated Mono/.net functionality或其他内容有关吗？

Answer 1

您可以使用命名管道，它使用共享内存与相同计算机上的其他应用程序进行通信。

转到文件 - ＆gt; 构建设置... 选择 PC，Mac＆amp; Linux Standalone 然后单击播放器设置... 。现在，将 Api兼容级别更改为 .NET 2.0 。

关闭并重新打开Visual Studio。现在，您可以导入using System.IO.Pipes;并能够使用NamedPipeServerStream和NamedPipeClientStream。

下面是一个非常简化的服务器和客户端。您必须在Thread中执行此操作，并且还应处理异常。

如果您不想使用Thread，还有异步参数（PipeOptions.Asynchronous）使其成为非阻塞运算符。它从那里变得复杂，你必须在MS doc上寻找一些例子。

简单服务器：

//Create Server Instance
NamedPipeServerStream server = new NamedPipeServerStream("MyCOMApp", PipeDirection.InOut, 1);
//Wait for a client to connect
server.WaitForConnection();
//Created stream for reading and writing
StreamString serverStream = new StreamString(server);
//Send Message to Client
serverStream.WriteString("Hello From Server");
//Read from Client
string dataFromClient = serverStream.ReadString();
UnityEngine.Debug.Log("Received from Client: " + dataFromClient);
//Close Connection
server.Close();

简单客户：

//Create Client Instance
NamedPipeClientStream client = new NamedPipeClientStream(".", "MyCOMApp",
               PipeDirection.InOut, PipeOptions.None,
               TokenImpersonationLevel.Impersonation);

//Connect to server
client.Connect();
//Created stream for reading and writing
StreamString clientStream = new StreamString(client);
//Read from Server
string dataFromServer = clientStream.ReadString();
UnityEngine.Debug.Log("Received from Server: " + dataFromServer);
//Send Message to Server
clientStream.WriteString("Bye from client");
//Close client
client.Close();

来自MS Doc的StreamString课程：

public class StreamString
{
    private Stream ioStream;
    private UnicodeEncoding streamEncoding;

    public StreamString(Stream ioStream)
    {
        this.ioStream = ioStream;
        streamEncoding = new UnicodeEncoding();
    }

    public string ReadString()
    {
        int len = 0;

        len = ioStream.ReadByte() * 256;
        len += ioStream.ReadByte();
        byte[] inBuffer = new byte[len];
        ioStream.Read(inBuffer, 0, len);

        return streamEncoding.GetString(inBuffer);
    }

    public int WriteString(string outString)
    {
        byte[] outBuffer = streamEncoding.GetBytes(outString);
        int len = outBuffer.Length;
        if (len > UInt16.MaxValue)
        {
            len = (int)UInt16.MaxValue;
        }
        ioStream.WriteByte((byte)(len / 256));
        ioStream.WriteByte((byte)(len & 255));
        ioStream.Write(outBuffer, 0, len);
        ioStream.Flush();

        return outBuffer.Length + 2;
    }
}

你可以有一个他们都写和读的文件。您可以在其中加上时间戳，以显示上次写入消息的时间
