Use the ContainsValue() method to check if Hashtable contains a value









    
using  System;
using  System.Collections;

class  MainClass
{

    public  static  void  Main()
    {
        Hashtable  myHashtable  =  new  Hashtable();

        myHashtable.Add("AL",  "Alabama");
        myHashtable.Add("CA",  "California");
        myHashtable.Add("FL",  "Florida");
        myHashtable.Add("NY",  "New  York");
        myHashtable.Add("WY",  "Wyoming");

        foreach  (string  myKey  in  myHashtable.Keys)
        {
            Console.WriteLine("myKey  =  "  +  myKey);
        }
        foreach(string  myValue  in  myHashtable.Values)
        {
            Console.WriteLine("myValue  =  "  +  myValue);
        }
        
        if  (myHashtable.ContainsValue("Florida"))
        {
            Console.WriteLine("myHashtable  contains  the  value  Florida");
        }
    }
}
    
   
  
   



Output

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