AW: AW: [Mono-list] Checking key existance in a NameValueCollection

[Shawn Vose]

I think it should be in a try statement because if the key doesnt exist 
it will throw an  exception.
Additionally in c# it would use [] instead of ()

try{
    if !(Request.Form["key"]  == null){
      // do something
    }else{
       //do something to handle a null value
    }
}catch(Exception e){
    //the key doesnt exists
}
