ist possible to have another if statement after the first if statement..

this is just an example

private void button_click(object sender, eventargs e)
else if(age>10||age<20);"example");


//can i have another if statement here???
if(something ==eg)

Not really understanding what you mean...You can have as many if statements as you want wherever you want pretty much.

Yes you can, except you have mis-matched {} in your example.
