如何使字节值用作int

Question

我正在尝试让服务器能够接收客户端字节并将其用作整数，我该怎么做？这是我试图修复的代码〜唯一的错误就是它无法将字节处理为int ...请帮帮我

try
             { 

                byte[] received = new byte[1024];
                mStream.Read(received, 0, received.Length);
                updateUI("Received: " + Encoding.ASCII.GetString(received));


                int Cir;
                Cir = received;

                switch (Cir)
                {
                    case 1 :
                        serialPort1.PortName = "COM5";
                        serialPort1.BaudRate = 9600;
                        serialPort1.DataBits = 8;
                        serialPort1.Parity = System.IO.Ports.Parity.None;
                        serialPort1.StopBits = System.IO.Ports.StopBits.One;
                        serialPort1.Open();
                        serialPort1.Write("a");
                        serialPort1.Close();
                        break;
                    case 2:
                        serialPort1.PortName = "COM5";
                        serialPort1.BaudRate = 9600;
                        serialPort1.DataBits = 8;
                        serialPort1.Parity = System.IO.Ports.Parity.None;
                        serialPort1.StopBits = System.IO.Ports.StopBits.One;
                        serialPort1.Open();
                        serialPort1.Write("a");
                        serialPort1.Close();
                        break;


                }

Answer 1

//Try converting the byte value and setting your int to it that way
int cir = Convert.ToInt32(recieved);

Converting to Int32

Answer 2

//Try writing the value in a console to see what you have
Console.WriteLine(received);
Console.Readline(); 

或者，如果您正在使用像Visual Studios这样的IDE，那么您可以在执行期间停止该功能并检查值。
