Unity3D:UDPSocket通信模块

先上接口

using System;

namespace YDB.UDPSocket
{
    public interface IUDPSocket
    {
        /// 

        /// 连接并接收数据
        /// 
        void ReceivePackage(string receiveIP_str, string receivePort_str, Action<byte[]> action);
        /// 

        /// 发送数据
        /// 
        /// 
        /// 
        /// 
        void SendPackage(string sendIP_Str, string sendPort_int, byte[] data);
        /// 

        /// 关闭
        /// 
        void ShutDown();
    }
}
