অভিধানে কী/মান জোড়ার সংখ্যা পেতে, কোডটি নিম্নরূপ -
উদাহরণ
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(){
Dictionary<string, string> dict =
new Dictionary<string, string>();
dict.Add("One", "Chris");
dict.Add("Two", "Steve");
dict.Add("Three", "Messi");
dict.Add("Four", "Ryan");
dict.Add("Five", "Nathan");
Console.WriteLine("Count of elements = "+dict.Count);
Console.WriteLine("\nKey/value pairs...");
foreach(KeyValuePair<string, string> res in dict){
Console.WriteLine("Key = {0}, Value = {1}", res.Key, res.Value);
}
if (dict.ContainsValue("Angelina"))
Console.WriteLine("Value found!");
else
Console.WriteLine("Value isn't in the dictionary!");
dict.Clear();
Console.WriteLine("Cleared Key/value pairs...");
foreach(KeyValuePair<string, string> res in dict){
Console.WriteLine("Key = {0}, Value = {1}", res.Key, res.Value);
}
Console.WriteLine("Count of elements now = "+dict.Count);
}
} আউটপুট
এটি নিম্নলিখিত আউটপুট −
তৈরি করবেCount of elements = 5 Key/value pairs... Key = One, Value = Chris Key = Two, Value = Steve Key = Three, Value = Messi Key = Four, Value = Ryan Key = Five, Value = Nathan Value isn't in the dictionary! Cleared Key/value pairs... Count of elements now = 0
উদাহরণ
এখন আরেকটি উদাহরণ দেখা যাক -
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(){
Dictionary<string, string> dict = new Dictionary<string, string>();
dict.Add("One", "David");
dict.Add("Two", "Brian");
dict.Add("Three", "Paul");
dict.Add("Four", "Ryan");
dict.Add("Five", "Nathan");
Console.WriteLine("Count of elements = "+dict.Count);
}
} আউটপুট
এটি নিম্নলিখিত আউটপুট −
তৈরি করবেCount of elements = 5
