Serialization problems with System.IO.MemoryStream
I have been working on saving my game information though serialization, but i encountered a few problems with the C# code
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
public class PPSerialization {
public static BinaryFormatter binaryFormater = new BinaryFormatter ();
public static void Save(string saveTag, object obj) {
MemoryStream memoryString = new MemoryStream ();
**binaryFormater.Serialize (MemoryStream, obj);
string temp = System.Convert.ToBase64String(MemoryStream.ToArray());**
PlayerPrefs.SetString (saveTag, temp);
}
public static object Load(string saveTag){
string temp = PlayerPrefs.GetString (saveTag);
if (temp == string.Empty) {
return null;
}
MemoryStream memoryStream = new MemoryStream (System.Convert.FromBase64String(temp));
return binaryFormater.Deserialize (memoryStream);
}
}
The system says there are problems with the lines in bold. The code is old so I don't know if i need to update it or if it's a simple mistake. If anyone could help that would be grateful.
The lines in bold are the ones with two asterisks around them.
When you use any stream always use the 'using' space, so the stream disposes of its objects correctly.
using(MemoryStream memStream = new MemoryStream(100))
{
//code
}
Also
binaryFormater.Serialize (MemoryStream, obj);
string temp =
System.Convert.ToBase64String(MemoryStream.ToArray());
you are directly passing the MemoryStream type, shouldn't you be passing your stream object
memoryString
Final result:
string temp = string.Empty;
using (MemoryStream memoryString = new MemoryStream ()) {
binaryFormater.Serialize (memoryString, obj);
temp = System.Convert.ToBase64String(MemoryStream.ToArray());
}
Don't forget to add the using in the load function too.
