Save and load arrays into an XML file

Questions & Answers

Hi,

I’m trying to save and load my IOS game data. I have multiples arrays of strings, int, bools or floats.
I would like to save that into an XML file, how can I do to export and import theses arrays easily? Is there a way of saving each arrays as a long string composed by the array components separated by | or ;.

So basicaly, to save I would build up a string from an array then exporting it to the xml. And to load, I would import the string the separate and fill out my array.

I’ve found the playerprefs (C# part) on the Unify I’m thinking to use that as a starting point.

#region Int Array

    /// <summary>
    /// Stores a Int Array or Multiple Parameters into a Key
    /// </summary>
    public static bool SetIntArray(string key, params int[] intArray)
    {
        if (intArray.Length == 0) return false;

        System.Text.StringBuilder sb = new System.Text.StringBuilder();
        for (int i = 0; i < intArray.Length - 1; i++)
            sb.Append(intArray*).Append("|");*

sb.Append(intArray[intArray.Length - 1]);

try { PlayerPrefs.SetString(key, sb.ToString()); }
catch (Exception e) { return false; }
return true;
}

///


/// Returns a Int Array from a Key
///
public static int[] GetIntArray(string key)
{
if (PlayerPrefs.HasKey(key))
{
string[] stringArray = PlayerPrefs.GetString(key).Split(“|”[0]);
int[] intArray = new int[stringArray.Length];
for (int i = 0; i < stringArray.Length; i++)
intArray = Convert.ToInt32(stringArray*);*
return intArray;
}
return new int[0];
}
Any ideas, advices?

Problem Solved:

I used theses lines:
System.Text.StringBuilder sb = new System.Text.StringBuilder();
for (int i = 0; i < intArray.Length - 1; i++)
sb.Append(intArray*).Append(“|”);*
sb.Append(intArray[intArray.Length - 1]);
and I’ve replaced the intArray by my actual array and exported the sb to the Xml file with the xml load and save from the unify.
