SortedDictionary.ContainsValue() Method in C#
The SortedDictionary.ContainsValue() method in C# is used to determine whether the SortedDictionary<TKey, TValue> contains an element with the specified value.
Syntax
The syntax is as follows −
public bool ContainsValue (TValue val);
Above, the value val is the value to be searched in the SortedDictionary<TKey, TValue>.
Example
Let us now see an example −
using System;
using System.Collections;
using System.Collections.Generic;
public class Demo {
public static void Main(){
SortedDictionary<int, string> sortedDict = new SortedDictionary<int, string>();
sortedDict.Add(100, "Inspiron");
sortedDict.Add(200, "Alienware");
sortedDict.Add(300, "Projectors");
sortedDict.Add(400, "XPS");
Console.WriteLine("SortedDictionary key-value pairs...");
IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator();
while (demoEnum.MoveNext())
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
Console.WriteLine("Count of SortedDictionary key-value pairs = "+sortedDict.Count);
sortedDict.Add(800, "Notebook");
sortedDict.Add(10000, "Bluetooth Speaker");
Console.WriteLine("
SortedDictionary key-value pairs...UPDATED");
demoEnum = sortedDict.GetEnumerator();
while (demoEnum.MoveNext())
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
Console.WriteLine("Count of SortedDictionary key-value pairs (UPDATED) = "+sortedDict.Count);
Console.WriteLine("Is the value in the SortedDictionary key-value pairs = "+sortedDict.ContainsValue("Notebook"));
sortedDict.Clear();
Console.WriteLine("
Count of SortedDictionary key-value pairs (UPDATED) = "+sortedDict.Count);
}
}Output
This will produce the following output −
SortedDictionary key-value pairs... Key = 100, Value = Inspiron Key = 200, Value = Alienware Key = 300, Value = Projectors Key = 400, Value = XPS Count of SortedDictionary key-value pairs = 4 SortedDictionary key-value pairs...UPDATED Key = 100, Value = Inspiron Key = 200, Value = Alienware Key = 300, Value = Projectors Key = 400, Value = XPS Key = 800, Value = Notebook Key = 10000, Value = Bluetooth Speaker Count of SortedDictionary key-value pairs (UPDATED) = 6 Is the value in the SortedDictionary key-value pairs = True Count of SortedDictionary key-value pairs (UPDATED) = 0
Example
Let us now see another example −
using System;
using System.Collections;
using System.Collections.Generic;
public class Demo {
public static void Main(){
SortedDictionary<int, string> sortedDict = new SortedDictionary<int, string>();
sortedDict.Add(1, "One");
sortedDict.Add(2, "Two");
sortedDict.Add(3, "Three");
sortedDict.Add(4, "Four");
sortedDict.Add(5, "Five");
sortedDict.Add(6, "Six");
Console.WriteLine("SortedDictionary key-value pairs...");
IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator();
while (demoEnum.MoveNext())
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
Console.WriteLine("Count of SortedDictionary key-value pairs = "+sortedDict.Count);
sortedDict.Add(7, "Seven");
sortedDict.Add(8, "Eight");
Console.WriteLine("
SortedDictionary key-value pairs...UPDATED");
demoEnum = sortedDict.GetEnumerator();
while (demoEnum.MoveNext())
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
Console.WriteLine("Count of SortedDictionary key-value pairs (UPDATED) = "+sortedDict.Count);
Console.WriteLine("Is the value in the SortedDictionary key-value pairs = "+sortedDict.ContainsValue("Eleven"));
sortedDict.Clear();
Console.WriteLine("
Count of SortedDictionary key-value pairs (UPDATED) = "+sortedDict.Count);
}
}Output
This will produce the following output −
SortedDictionary key-value pairs... Key = 1, Value = One Key = 2, Value = Two Key = 3, Value = Three Key = 4, Value = Four Key = 5, Value = Five Key = 6, Value = Six Count of SortedDictionary key-value pairs = 6 SortedDictionary key-value pairs...UPDATED Key = 1, Value = One Key = 2, Value = Two Key = 3, Value = Three Key = 4, Value = Four Key = 5, Value = Five Key = 6, Value = Six Key = 7, Value = Seven Key = 8, Value = Eight Count of SortedDictionary key-value pairs (UPDATED) = 8 Is the value in the SortedDictionary key-value pairs = False Count of SortedDictionary key-value pairs (UPDATED) = 0
