C# | Check if two SortedSet<T> objects are equal

C# Program to Check Given Strings are Equal or Not Using equal to (==) Operator

Last Updated : 11 Nov, 2021

Given two strings we need to check if they are equal by using the == operator. The == Operator compares the reference identity i.e. whether they are referring to the same identity in the heap. If they are equal then it will return true, otherwise, return false.

Example:

Input
String 1 : geeks
String 2 : geeks
Output   : Equal

Input
String 1 : geeks
String 2 : geeqs
Output   : Not Equal

Method:

For the given two strings compare them by using == operator

If it returns true then the strings are equal.

If it returns false then the strings are not equal.

Example 1:

C#

// C# program to check given strings are 
// equal or not. Using == operator
using System;
 
class GFG{
     
public static void Main()
{
    string str1 = "geeks";
    string str2 = "geeks";
     
    // Here we use == operator to check 
    // the equality of the strings
    Console.WriteLine(str1 == str2);
}
}

Output

True

Example 2:

C#

// C# program to check given strings
// are equal or not. Using == operator
using System;
 
class GFG{
     
public static void Main()
{
    string str1 = "geeks";
    string str2 = "geeqs";
     
    // Here we use == operator to check 
    // the equality of the strings
    Console.WriteLine(str1 == str2);
}
}

Output

False

But the == operator might not work as expected when we are comparing strings whose reference identities are not the same. Let us understand with the help of the below example:

C#

// C# program to check given strings
// are equal or not. Using == operator
using System;  
 
class GFG{
     
static void Main(string[] args)  
{ 
    object str1 = "geeks";   
    object str2 = new string("geeks");       
     
    Console.WriteLine(str1 == str2);  
}       
}  

Output

False

Compare Strings for equality or lexicographical order in different programming Languages

Given two strings string1 and string2, the task is to check if these two strings are equal or not. Examples: Input: string1 = â€œGeeksforGeeksâ€, string2 = â€œGeeksforGeeksâ€ Output: Yes Input: string1 = â€œGeeks for Geeksâ€, string2 = â€œGeeks for Geeksâ€ Output: Yes Input: string1 = â€œGeeksforGeeksâ€, string2 =
