Serialize the text

Greetings fellows! Is it possible to serialize the string value? Currently, I have a script working all right if 2 variables are integer or float, but it shows error, once I change data type to string.

 using UnityEngine;
 using System.Collections;
 
 public class serializeee : MonoBehaviour {
 
     public string text1 = "This is text 1";
     public string text2 = "This is text 2";
 
     void Update () {
     }
 
     void OnSerializeNetworkView(BitStream stream, NetworkMessageInfo info) {
         if (stream.isWriting) {
             text1 = text2;
             stream.Serialize(ref text1);
         } else {
             stream.Serialize(ref text1);
             text2 = text1;
         }
     }
 }
 

Could you please suggest what is wrong and how to fix it?

Thanks!
