Csharp/CSharp Tutorial/Generic/Generic SortedList

Use the ContainsKey() method to check if mySortedList contains a key

using System;
using System.Collections;
class MainClass
{
  public static void Main()
  {
    SortedList mySortedList = new SortedList();
    mySortedList.Add("NY", "New York");
    mySortedList.Add("FL", "Florida");
    mySortedList.Add("AL", "Alabama");
    mySortedList.Add("WY", "Wyoming");
    mySortedList.Add("CA", "California");
    foreach (string myKey in mySortedList.Keys)
    {
      Console.WriteLine("myKey = " + myKey);
    }
    foreach(string myValue in mySortedList.Values)
    {
      Console.WriteLine("myValue = " + myValue);
    }
    
    if (mySortedList.ContainsKey("FL"))
    {
      Console.WriteLine("mySortedList contains the key FL");
    }
  }
}

myKey = AL
myKey = CA
myKey = FL
myKey = NY
myKey = WY
myValue = Alabama
myValue = California
myValue = Florida
myValue = New York
myValue = Wyoming
mySortedList contains the key FL

Use the keys to obtain the values from a generic SortedList<TK, TV>

using System;  
using System.Collections.Generic;  
  
class MainClass {  
  public static void Main() {  
    SortedList<string, double> sl = new SortedList<string, double>();  
       
    sl.Add("A", 7);  
    sl.Add("B", 5);  
    sl.Add("C", 4);  
    sl.Add("D", 9);  
 
    // Get a collection of the keys.  
    ICollection<string> c = sl.Keys;  
  
      
    foreach(string str in c)  
      Console.WriteLine("{0}, Salary: {1:C}", str, sl[str]);  
  
    Console.WriteLine();  
  }  
}

A, Salary: $7.00
B, Salary: $5.00
C, Salary: $4.00
D, Salary: $9.00
