Compilor Error using Dictonary collection

Hi everyone,

Ive got some code here that utilises a dictionary construct. And in this dictionary construct i have specified a gameobject as the key type and a GENERIC list of type component as the value type. However i seem to be recieving some compile errors. I just want to make sure that i am using the types correctly... I am getting these sort of compile errors;

Insert "semi colon on line 1" (which i already have),and for line 8, i get 3 errors "expecting > found >>" ," expecting > found ("," expecting ( found )"..

Also is looping over a dictionary the same as looping through a hashtable?

Thanks alot in advance

The code i have is here.

     using System.Collections.Generic;
 
 
 var componentsExtracted:Dictionary;
 
 function Start () 
 {
     componentsExtracted = new Dictionary.<GameObject,List.<Component>>();
 }
 
 
 function findComponent(selectedObject:GameObject) 
 {
     if(Input.GetKeyUp(KeyCode.E)) {
     //RETRIEVES ALL COMPONENTS IN THE SELECTED OBJECT    
         var componentsFound:Component[] =  selectedObject.GetComponents(typeof(Component));
     //RETRIEVE A RANDOM COMPONENT
         var component:Component = findRandomComponent(componentsFound);
     //ADD COMPONENT TO WITH ORIGIN (GAMEOBJECT) REFERENCE TO DICTIONARY
         addToDictionary();                       
     }
     
 }
 
 private function findRandomComponent(componentsFound:Component[]) 
 {
 // INITIALISE COMPONENT CONTAINER
     var chosenComponent:Component;
     
     do 
     {
     // RETRIEVES A RANDOM NUMBER
         var ranNum:int = Random.Range(0,componentsFound.length);
     // RETRIEVES A CHOSEN COMPONENT
         chosentComponent = componentsFound[ranNum];
     }
     
 // WHILE COMPONENT IS NOT OF TRANSORM...PARTICLEEMITTER....(ADD MORE)
     while((typeof(chosenComponent)!= Transform) && (typeof(chosenComponent)!= ParticleEmitter));
     
 // RETURN RANDOM COMPONENT
     return chosenComponent;
 }
 
 private function addToDictionary() {
     
 
 }
