需要帮助将int数组从C＃发送到arduino

Question

I have the following integer array [1,2,3,4,5,6,7,8,9]

I need to send it to Arduino UNO.

I've tried to send it as array of byte but it doesn't work.

C# code:

using System.IO.Ports;

private void Form1_Load(object sender, EventArgs e)
{serialPort1.Open();}

byte[] OUT = { 1,2,3,4,5,6,7,8,9 }; 

serialPort1.Write(OUT, 0, 12);

arduino code

void setup() {

  Serial.begin(9600);

  for (byte aPin = start; aPin <= 13 ; aPin++) {
    pinMode(aPin, OUTPUT);}

  for (byte apin = start; apin <= 13 ; apin++) {
    digitalWrite(apin,HIGH);}


}


void loop(){

//Serial communication step
//Serial.write("6564456464646");

if(Serial.available()){

  for(char j=0;j<Serial.available();j++)
  {input[j]=Serial.read();}

You can use this part for c# part:

         Connect();
        if (serialPort1.IsOpen)
        {
            int MyInt = ToInt32(lblFirstNumber.Text);
            byte[] b = GetBytes(MyInt);
            serialPort1.Write(b, 0, 1);

            int MyInt2 = ToInt32(txtFirstNumber.Text);
            byte[] z = GetBytes(MyInt2);
            serialPort1.Write(z, 0, 1);

            int MyInt3 = ToInt32(txtSecondNumber.Text);
            byte[] p = GetBytes(MyInt3);
            serialPort1.Write(p, 0, 1);

            serialPort1.Close();
        }
        else
        {
            MessageBox.Show("Please control your connection");
        }
