C# SerialPort ReadByte or Read?

[LukasMalik]

Hi all,

I have 2 different read methods:

1)
public void Read()
{
while(true)
{
oSerialPort.Rea d(bytesToReadAr ray, 0, bytesToReadArra y.Lenght);
}

// and EventHandled method on event .DataRecieved..
}
2)

public void Read2()
{
oSerialPort.Ope n();
}

void oSerialPort_Dat aRecieved(...)
{
int i = 0;

while (oSerialPort.By tesToRead > 0)
{
bytesToReadArra y.SetValue((byt e)oSerialPort.R eadByte(), i);
i++;
}
}

Both methods "work" = return some data. Read2() returns correct data, method Read() returns array but with wrong position of bytes.. On position of byte[0] is byte[1] and last byte is 0;

Which method is correct for reading Byte from port?

Thanks a lot
