c# serial

hi all vbforums,

[using Visual Studio 2008 Team System]

Nowadays I'm trying to communicate my Arduino with my C# program with using standart System.IO class. However despite I've added the serialPort object to my form, I couldn't succeed send and integer value with serialPort1.Write() method. I'm trying execute very simple code here's a little part of my program (you can see how it is easy)

Code:

---

serialPort1.Write(komut);
serialPort1.Write(data);

---

"komut" and "data" are my parameters, which is created by my function "veriGonder" (you can see the function below). And the methods that you can see @ above (serialPort1.Write methods) are in this veriGonder function.

Code:

---

private void veriGonder(string komut,string data)
{ do sth.. }

---

As I said, I'm just trying to send an integer (or byte is prefered) value but I couldn't send anything different than a string type (so, I've set the srialPort1 object settings correct, baudrate, stop bits etc..) And also I don't want to labour with lots of complex code stuffs.. (like in this web site)

I'll be happy if you can help.
Regards.

(P.S.: Can someone please show me how to flush this !hacking! serial buffer??)
