Removing all entries from the StringDictionary in C#
To remove all entries from the StringDictionary, the code is as follows −
Example
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("
StringDictionary2 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);
}
}Output
This will produce the following output −
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
Example
Let us see another example −
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);
}
}Output
This will produce the following output −
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
