C# | SortedDictionary.ContainsValue() Method
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." ); } } |
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" ); } } |
Value : Moscow is present
