As you know, Arduino IDE resets Arduino when Serial Monitor is opened.I want also my program to do it. But I don't know how.

I examined the source code of Arduino IDE(Serial.java & SerialMonitor.java) but can't find where it sends reset command. Please help about this issue.

I use C# to communicate with serial.

OK, I have solved this by sending DSR pulse as seen on code below: 

mySerial.DtrEnable = true;
mySerial.Open();
Thread.Sleep(1000);
mySerial.DtrEnable = false;
