unity SortedDictionary

Unity does not have a SortedDictionary class built-in, but it is possible to use the System.Collections.Generic.SortedDictionary class from the .NET framework by adding the namespace to the script:

using System.Collections.Generic;

Then you can declare and use a SortedDictionary object like this:

SortedDictionary<string, int> myDict = new SortedDictionary<string, int>();

myDict.Add("apple", 5);
myDict.Add("banana", 3);
myDict.Add("cherry", 7);
myDict.Add("durian", 2);

foreach (KeyValuePair<string, int> kvp in myDict)
{
    Debug.Log(kvp.Key + ": " + kvp.Value);
}

This will output:

apple: 5
banana: 3
cherry: 7
durian: 2

Note that the items are automatically sorted by the key (in this case, the string) in ascending order. To sort by a different criteria, you can provide a custom comparer to the SortedDictionary constructor.
