Not writing to file correctly

Hi, I want the code to write PlayerNameFinal and count to an array in leaderboard.txt when SaveScoreButton is pressed.

This is currently what is being written to the file: System.Collections.Generic.Dictionary`2[System.String,System.Int32]

Code:

using UnityEngine; using System.Collections; using System.Collections.Generic; using System.IO; using Vexe.FastSave; using Vexe.Runtime.Types;

public class GUI_Button : MonoBehaviour {

 public PlayerMovement GUIScript;
 public RandomSpawn GUIScript1;
 private int count = RandomSpawn.count;
 public string PlayerName = "Enter name";
 public string fileName = "leaderboard.txt";
 string[] PlayerAndScore = new string [1];
 public string PlayerNameFinal;
 public string count1 = "";
 private bool SaveScoreButton = false;

 void OnGUI ()
 {
     if (PlayerMovement.livess <= 0) 
     {
         GUI.Button (new Rect (400, 200, 300, 200), "Score:" + (count+10));
         PlayerName = GUI.TextField (new Rect (400, 400, 300, 100), PlayerName);
         SaveScoreButton = GUI.Button (new Rect (400, 500, 200, 100), "Save Score");
         CountToString ();
     }
 }
 void OnClick()
 {
     PlayerNameFinal = PlayerName;
 }
 void Start()
 {
     PlayerAndScore [0] = PlayerNameFinal;
     PlayerAndScore [1] = count1;
     System.IO.File.WriteAllLines(@"Desktop\Pixel Ninjav3.3\Assets\leaderboard.txt", PlayerAndScore);
 }
 void CountToString ()
 {
     count1 = count.ToString();
 }

}
