Get a collection of values in the StringDictionary in C#

To get a collection of values in the StringDictionary, the code is as follows −

Example

 Live Demo

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main(){
      StringDictionary strDict1 = new StringDictionary();
      strDict1.Add("S", "Home Appliances");
      strDict1.Add("T", "Smart Wearable Tech");
      strDict1.Add("U", "Electronics");
      strDict1.Add("V", "Toys");
      strDict1.Add("W", "Books");
      strDict1.Add("X", "Accessories");
      Console.WriteLine("StringDictionary elements...");
      foreach(DictionaryEntry d in strDict1){
         Console.WriteLine(d.Key + " " + d.Value);
      }
      Console.WriteLine("
Collection of keys and values...");
      String[] keyArr = new String[strDict1.Count];
      strDict1.Keys.CopyTo(keyArr, 0);
      for (int i = 0; i < strDict1.Count; i++) {
         Console.WriteLine("Key "+(i+1)+" = "+keyArr[i]+", Value "+(i+1)+" = "+strDict1[keyArr[i]]);
      }
      Console.WriteLine("
Does StringDictionary has key B? "+strDict1.ContainsKey("B"));
   }
}

Output

This will produce the following output −

StringDictionary elements...
x Accessories
s Home Appliances
t Smart Wearable Tech
u Electronics
v Toys
w Books
Collection of keys and values...
Key 1 = x, Value 1 = Accessories
Key 2 = s, Value 2 = Home Appliances
Key 3 = t, Value 3 = Smart Wearable Tech
Key 4 = u, Value 4 = Electronics
Key 5 = v, Value 5 = Toys
Key 6 = w, Value 6 = Books
Does StringDictionary has key B? False

Example

Let us see another example −

 Live Demo

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main(){
      StringDictionary strDict1 = new StringDictionary();
      strDict1.Add("A", "John");
      strDict1.Add("B", "Andy");
      strDict1.Add("C", "Tim");
      strDict1.Add("D", "Ryan");
      strDict1.Add("E", "Kevin");
      strDict1.Add("F", "Katie");
      strDict1.Add("G", "Brad");
      Console.WriteLine("StringDictionary elements...");
      foreach(DictionaryEntry d in strDict1){
         Console.WriteLine(d.Key + " " + d.Value);
      }
      Console.WriteLine("
Collection of keys and values...");
      String[] keyArr = new String[strDict1.Count];
      strDict1.Keys.CopyTo(keyArr, 0);
      for (int i = 0; i < strDict1.Count; i++) {
         Console.WriteLine("Key "+(i+1)+" = "+keyArr[i]+", Value "+(i+1)+" = "+strDict1[keyArr[i]]);
      }
      Console.WriteLine("
Does StringDictionary has key B? "+strDict1.ContainsKey("B"));
   }
}

Output

This will produce the following output −

tringDictionary elements...
a John
b Andy
c Tim
d Ryan
e Kevin
f Katie
g Brad
Collection of keys and values...
Key 1 = a, Value 1 = John
Key 2 = b, Value 2 = Andy
Key 3 = c, Value 3 = Tim
Key 4 = d, Value 4 = Ryan
Key 5 = e, Value 5 = Kevin
Key 6 = f, Value 6 = Katie
Key 7 = g, Value 7 = Brad
Does StringDictionary has key B? True
