What is the Keys property of SortedList class in C#?
Get the keys in the SortedList using the keys property of SortedList class in C#. We have first set the SortedList property with elements.
SortedList sl = new SortedList(); sl.Add("ST0", "One"); sl.Add("ST1", "Two"); sl.Add("ST2", "Three"); sl.Add("ST3", "Four"); sl.Add("ST4", "Five"); sl.Add("ST5", "Six"); sl.Add("ST6", "Seven");
Now use the keys property to get the keys.
ICollection key = sl.Keys;
The following is the complete code to implement keys property of SortedList class.
Example
using System; using System.Collections; namespace Demo { class Program { static void Main(string[] args) { SortedList sl = new SortedList(); sl.Add("ST0", "One"); sl.Add("ST1", "Two"); sl.Add("ST2", "Three"); sl.Add("ST3", "Four"); sl.Add("ST4", "Five"); sl.Add("ST5", "Six"); sl.Add("ST6", "Seven"); ICollection key = sl.Keys; foreach (string k in key) { Console.WriteLine(k); } } } }
Output
ST0 ST1 ST2 ST3 ST4 ST5 ST6
