Equals(Object) Method which is inherited from the Object class is used to check if a specified SortedDictionary object is equal to another SortedDictionary object or not.
Syntax:
CSharp
CSharp
public virtual bool Equals (object obj);Here, obj is the object which is to be compared with the current object. Return Value: This method return true if the specified object is equal to the current object otherwise it returns false. Below programs illustrate the use of above-discussed method: Example 1:
// C# code to check if the two
// SortedDictionary are equal or not
using System;
using System.Collections.Generic;
class GFG {
// Driver code
public static void Main()
{
// Creating a SortedDictionary named myDict
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 whether myDict is
// equal to itself or not
Console.WriteLine(myDict.Equals(myDict));
}
}
Output:
Example 2:
True
// C# code to check if the two
// SortedDictionary are equal or not
using System;
using System.Collections.Generic;
class GFG {
// Driver code
public static void Main()
{
// Creating a SortedDictionary named myDict
SortedDictionary<string, string> myDict1 =
new SortedDictionary<string, string>();
// Adding key/value pairs in myDict
myDict1.Add("I", "first");
myDict1.Add("II", "second");
myDict1.Add("III", "third");
myDict1.Add("IV", "fourth");
myDict1.Add("V", "fifth");
// Creating a SortedDictionary named myDict2
SortedDictionary<string, string> myDict2 =
new SortedDictionary<string, string>();
myDict2.Add("1st", "C");
myDict2.Add("2nd", "C++");
myDict2.Add("3rd", "Java");
myDict2.Add("4th", "C#");
myDict2.Add("5th", "HTML");
myDict2.Add("6th", "PHP");
// Checking whether myDict1 is
// equal to myDict2 or not
Console.WriteLine(myDict1.Equals(myDict2));
// Creating a new SortedDictionary
SortedDictionary<string, string> myDict3 =
new SortedDictionary<string, string>();
// Assigning myDict2 to myDict3
myDict3 = myDict2;
// Checking whether myDict3 is
// equal to myDict2 or not
Console.WriteLine(myDict3.Equals(myDict2));
}
}
Output:
Note: If the current instance is a reference type, the Equals(Object) method checks for reference equality.
False True
