सी # में स्ट्रिंग डिक्शनरी से सभी प्रविष्टियों को हटा रहा है

StringDictionary से सभी प्रविष्टियों को हटाने के लिए, कोड इस प्रकार है -

उदाहरण

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("StringDictionary1 elements...");
      foreach(DictionaryEntry d in strDict1){
         Console.WriteLine(d.Key + " " + d.Value);
      }
      Console.WriteLine("Does StringDictionary1 has key G? "+strDict1.ContainsKey("G"));
      StringDictionary strDict2 = new StringDictionary();
      strDict2.Add("A", "John");
      strDict2.Add("B", "Andy");
      strDict2.Add("C", "Tim");
      strDict2.Add("D", "Ryan");
      strDict2.Add("E", "Kevin");
      strDict2.Add("F", "Katie");
      strDict2.Add("G", "Brad");
      Console.WriteLine("\nStringDictionary2 elements...");
      foreach(DictionaryEntry d in strDict2){
         Console.WriteLine(d.Key + " " + d.Value);
      }
      Console.WriteLine("Count of key/value pairs in StringDictionary2 = " + strDict2.Count);
      strDict2.Clear();
      Console.WriteLine("Count of key/value pairs in StringDictionary2 (updated) = " + strDict2.Count);
   }
}

आउटपुट

यह निम्नलिखित आउटपुट देगा -

StringDictionary1 elements...
a John
b Andy
c Tim
d Ryan
e Kevin
f Katie
g Brad
Does StringDictionary1 has key G? True
StringDictionary2 elements...
a John
b Andy
c Tim
d Ryan
e Kevin
f Katie
g Brad
Count of key/value pairs in StringDictionary2 = 7
Count of key/value pairs in StringDictionary2 (updated) = 0

उदाहरण

आइए एक और उदाहरण देखें -

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main(){
      StringDictionary strDict = new StringDictionary();
      strDict.Add("A", "John");
      strDict.Add("B", "Andy");
      strDict.Add("C", "Tim");
      strDict.Add("D", "Ryan");
      Console.WriteLine("StringDictionary elements...");
      foreach(DictionaryEntry d in strDict){
         Console.WriteLine(d.Key + " " + d.Value);
      }
      Console.WriteLine("Count of key/value pairs in StringDictionary = " + strDict.Count);
      strDict.Clear();
      Console.WriteLine("Count of key/value pairs in StringDictionary (updated) = " + strDict.Count);
   }
}

आउटपुट

यह निम्नलिखित आउटपुट देगा -

StringDictionary elements...
a John
b Andy
c Tim
d Ryan
Count of key/value pairs in StringDictionary = 4
Count of key/value pairs in StringDictionary (updated) = 0
