Sorted Dictionary Classes:
- SortedList
- SortedList<Key, Value>
- SortedDictionary <Key, Value>

| Name | Description |
|---|---|

| SortedDictionary<TKey, TValue>(IComparer<TKey>) | Initializes a new instance of the SortedDictionary<TKey, TValue> class that is empty and uses the specified IComparer<T> implementation to compare keys. |
| SortedDictionary <TKey, TValue>(IDictionary<TKey, TValue>) |
Initializes a new instance of the SortedDictionary<TKey, TValue> class that contains elements copied from the specified IDictionary<TKey, TValue> and uses the default IComparer<T> implementation for the key type. |
| SortedDictionary <TKey, TValue>(IDictionary<TKey, TValue>, IComparer<TKey>) |
Initializes a new instance of the SortedDictionary<TKey, TValue>
class that contains elements copied from the specified IDictionary<TKey, TValue> and uses the specified IComparer<T> implementation to compare keys. |

- Let's see an example of generic SortedDictionary<TKey, TValue> class that stores elements using Add() method and iterates elements using for-each loop.
- Here, we are using KeyValuePair class to get key and value.

{
public static void Main(string[] args)
{
SortedDictionary<string, string> names = new SortedDictionary<string,
string>();
names.Add("1","Sonoo");
names.Add("4","Peter");
names.Add("5","James");
names.Add("3","Ratan");
names.Add("2","Irfan");
foreach (KeyValuePair<string, string> kv in names)
{
Console.WriteLine(kv.Key+" "+kv.Value);
}
}
}
