This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
I think I understand what you are trying to do, but the way you are trying makes little sense in isolation.
Perhaps if you show us the whole fragment you have already to read the data and store it, and explain what problem that gives (with an example if possible) it would help?

Solution 1

That's easy:

C#

private byte[] data = new byte[200];
private int index = 0;
...
   if (index < data.Length)
      {
      data[index++] = recievedByteValue;
      }

This is my code.When i run this first byte is saved in tempbuf's 0 th position .But when i got second byte,the first value is cleared:-(

private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
{
int bytes = serialPort1.BytesToRead;
byte[] byte_buffer = new byte[200];
byte[] tempbuf = new byte[200];
byte[]tempbuf2=new byte[200];
byte[] ar = new byte[20];
byte[] ssd = new byte[4];
byte[] ctrl = new byte[20];

string pp = "";
string ll = "";

serialPort1.Read(byte_buffer, 0, bytes);

if (i == 0)
{
index = byte_buffer[0];
}
// int j;
// byte_buffer.CopyTo(tempbuf,i);
tempbuf[q++] = byte_buffer[0];
// array[index] = TestSerializer.MarshalToStructureArray(tempbuf, tempbuf.Length);
// q++;
i++;
if (i == 200)
{

array[index] = TestSerializer.MarshalToStructureArray(tempbuf, tempbuf.Length);
if (textBox30.InvokeRequired)
{

this.Invoke(((MethodInvoker)delegate
{
textBox30.Text = index.ToString();
}));
// return;
}
i = 0;
}
if (q == 200)
{

q = 0;
}

How can i solve this?
