Equals(Object) Method which is inherited from the Object class is used to check if a specified StringDictionary object is equal to another StringDictionary 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 whether two
// StringDictionary objects
// are equal or not
using System;
using System.Collections.Specialized;
class GFG {
// Driver method
public static void Main()
{
// Creating a StringDictionary named myDict
StringDictionary myDict = new StringDictionary();
// Adding key and value in myDict
myDict.Add("1", "C");
myDict.Add("2", "C++");
myDict.Add("3", "Java");
myDict.Add("4", "C#");
// Checking whether myDict is
// equal to itself or not
Console.WriteLine(myDict.Equals(myDict));
}
}
// C# code to check whether two// StringDictionary objects// are equal or notusing System;using System.Collections.Specialized;class GFG { // Driver method public static void Main() { // Creating a StringDictionary named myDict StringDictionary myDict = new StringDictionary(); // Adding key and value in myDict myDict.Add("1", "C"); myDict.Add("2", "C++"); myDict.Add("3", "Java"); myDict.Add("4", "C#"); // Checking whether myDict is // equal to itself or not Console.WriteLine(myDict.Equals(myDict)); }}
Output:
Example 2:
True
// C# code to check whether two
// StringDictionary objects
// are equal or not
using System;
using System.Collections.Specialized;
class GFG {
// Driver method
public static void Main()
{
// Creating a StringDictionary named myDict
StringDictionary myDict1 = new StringDictionary();
// 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 StringDictionary named myDict2
StringDictionary myDict2 = new StringDictionary();
myDict2.Add("Australia", "Canberra");
myDict2.Add("Belgium", "Brussels");
myDict2.Add("Netherlands", "Amsterdam");
myDict2.Add("China", "Beijing");
myDict2.Add("Russia", "Moscow");
myDict2.Add("India", "New Delhi");
// Checking whether myDict1 is
// equal to myDict2 or not
Console.WriteLine(myDict1.Equals(myDict2));
// Creating a new StringDictionary
StringDictionary myDict3 = new StringDictionary();
// Assigning myDict2 to myDict3
myDict3 = myDict2;
// Checking whether myDict3 is
// equal to myDict2 or not
Console.WriteLine(myDict3.Equals(myDict2));
}
}
// C# code to check whether two// StringDictionary objects// are equal or notusing System;using System.Collections.Specialized;class GFG { // Driver method public static void Main() { // Creating a StringDictionary named myDict StringDictionary myDict1 = new StringDictionary(); // 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 StringDictionary named myDict2 StringDictionary myDict2 = new StringDictionary(); myDict2.Add("Australia", "Canberra"); myDict2.Add("Belgium", "Brussels"); myDict2.Add("Netherlands", "Amsterdam"); myDict2.Add("China", "Beijing"); myDict2.Add("Russia", "Moscow"); myDict2.Add("India", "New Delhi"); // Checking whether myDict1 is // equal to myDict2 or not Console.WriteLine(myDict1.Equals(myDict2)); // Creating a new StringDictionary StringDictionary myDict3 = new StringDictionary(); // 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
