About "translating" js into C#

Hello everyone, I was trying to "translate" a JS into a C# script. But I've just learned unity for 1 month and I kept making mistakes. I've finished tranlating most of it but there are still mistakes I wasn't able to correct, can anybody help me plz? REALLY need help here...with a desperate and thankful heart~!

Original one:

 #pragma strict
 
     public var objname = ""; //this is the field where you put the name to request
     var formText = ""; //this field is where the messages sent by PHP script will be in
     var URL = "XXX"; //the distant script URL
     
      
     public var textrect = Rect (10, 90, 500, 50); //just make a GUI object rectangle
      
     function OnGUI() {
         
         GUI.Label( Rect (10, 10, 80, 20), "Object name" ); //text with object name
         
          var c = gameObject.GetComponent("OnScreenKeyboardExample");
         //objname = OnScreenKeyboard.editableString;
         //objname.GetType().GetField(editableString).GetValue(objname);
         //objname = 
         //GUI.TextField ( Rect (90, 10, 100, 20), objname ); //here you will insert the new value to variable objname
          
         if ( GUI.Button ( Rect (10, 50, 100, 20) , "Try" ) )  //just a button
         { 
             Login();
         }
         GUI.TextArea( textrect, formText );
     }
          
     function Login() {
         var form = new WWWForm(); //here you create a new form connection
         form.AddField( "objectname", objname );
         var w = WWW(URL, form); //here we create a var called 'w' and we sync with our URL and the form
         yield w; //we wait for the form to check the PHP file, so our script dont just hang
         if (w.error != null) {
             print(w.error); //if there is an error, tells us
         } else {
             print("Test OK");
             formText = w.data; //here we return the data our PHP told us
             w.Dispose(); //clear our form in game
             
         }
      
         objname = ""; //just clean our variables
     }
