C# | SortedDictionary.ContainsValue() Method

Last Updated : 01 Feb, 2019

This method is used to check whether the SortedDictionary<TKey, TValue> contains an element with the specified value or not.

Syntax:

public bool ContainsValue (TValue value);

Here, the value is the Value to locate in the SortedDictionary. The value can be null for reference types.

Return Value: This method returns true if the SortedDictionary contains an element with the specified value otherwise it returns false.

Below are the programs to illustrate the use of SortedDictionary<TKey, TValue>.ContainsValue() Method:

Example 1:

// C# code to check if a value 
// is present or not in a  
// SortedDictionary. 
using System; 
using System.Collections.Generic; 
  
class GFG { 
  
    // Driver code 
    public static void Main() 
    { 
  
        // Create a new SortedDictionary 
        // of strings, with string keys. 
        SortedDictionary<string, string> myDict =  
          new SortedDictionary<string, string>(); 
  
        // Adding key/value pairs in myDict 
        myDict.Add("Australia", "Canberra"); 
        myDict.Add("Belgium", "Brussels"); 
        myDict.Add("Netherlands", "Amsterdam"); 
        myDict.Add("China", "Beijing"); 
        myDict.Add("Russia", "Moscow"); 
        myDict.Add("India", "New Delhi"); 
  
        // Checking the value "India" but 
        // here "India" is the key 
        if (myDict.ContainsValue("India")) 
            Console.WriteLine("Value : India is present."); 
  
        else
            Console.WriteLine("Value : India is not present."); 
    } 
} 

Output:

Value : India is not present.

Example 2:

// C# code to check if a value 
// is present or not in a  
// SortedDictionary. 
using System; 
using System.Collections.Generic; 
  
class GFG { 
  
    // Driver code 
    public static void Main() 
    { 
  
        // Create a new SortedDictionary 
        // of strings, with string keys. 
        SortedDictionary<string, string> myDict =  
           new SortedDictionary<string, string>(); 
  
        // Adding key/value pairs in myDict 
        myDict.Add("Australia", "Canberra"); 
        myDict.Add("Belgium", "Brussels"); 
        myDict.Add("Netherlands", "Amsterdam"); 
        myDict.Add("China", "Beijing"); 
        myDict.Add("Russia", "Moscow"); 
        myDict.Add("India", "New Delhi"); 
  
        // Checking for value Moscow 
        if (myDict.ContainsValue("Moscow")) 
            Console.WriteLine("Value : Moscow is present"); 
  
        else
            Console.WriteLine("Value : Moscow is absent"); 
    } 
}
