Problem reading csv file when last semicolon is missing

I have a csv file with this text inside

Cube;Mat_3;

Sphere;Mat_2;

Cylinder;Mat_6;

This is the script that load the file, reads its content and then assigns the materials to the relative objects.

 //Variables
 private var update : int;
 private var textAsset : TextAsset;
 private var oggetti = new Array ();
 private var materiali = new Array ();
 private var linee : String[];
 private var i : int;
 
 function Start () {
     //initialization
     update=1;
     i=0;
 }
 
 function Update () {
     //We need to update?
     if (update==1){
         //get text from a csv file
         textAsset = Resources.Load("settings", TextAsset);
         linee = textAsset.text.Split("\n"[0]);
         //handle the content in 2 string[] (object names, material names)
         for(i=1; i<linee.Length ; i++){
             if(linee[i]!=""){
                 oggetti.Push(linee[i].Split(";"[0])[0].ToString());
                 materiali.Push(linee[i].Split(";"[0])[1].ToString());
                 
             }
         }
         //for each object element set the material if the file exist 
         for(i=0; i<oggetti.length ; i++){
             //here is my problem
             if(Resources.Load(materiali[i], typeof(Material)) as Material){
                 gameObject.Find(oggetti[i]).renderer.material = Resources.Load(materiali[i], typeof(Material)) as Material;
             }
         }
         //we don't need to update again
         update=0;
     }
     
 }

My problem is: the csv file need, for each column, a final semicolon to load the right material, if the semicolon is missing, the material won't be loaded.

Example row:

Cube;Mat_2

Resouces.Load(materiali[i]) won't find the material

Example row:

Cube;Mat_2;

Resouces.Load(materiali[i]) will find the material

the strangest thing is that if I debug.log(materiali[i]) the console will output the same result. Using ToString() on materiali[i] doesn't helps, Excel saves the csv files without the last semicolon, so I need to add it by hand. There is a solution to make it work without manipulate the file? Thanks
