The Equals() method can be used to check if two strings are equal in C#. Two strings are considered equal if they have the same string values. The Equals() method returns True if the two strings are equal. Otherwise, it returns False.
string1.Equals(string2);
string1: The first string to be checked.
string2: The second string to be checked.
The return value is a boolean. The Equals() method returns True if the strings are equal, and False if they are not.
In the code example below, we define and initialize several strings. Then, we use the Equals() method to check if some of them are equal.
// create our classclass StringEquality{// main methodstatic void Main(){// define and initialize string variablesstring string1 = "Google";string string2 = "Meta";string string3 = "Facebook";string string4 = "Meta";// check if strings are equalbool a = string1.Equals(string2);bool b = string2.Equals(string4);bool c = string3.Equals(string4);bool d = string4.Equals(string2);// print returned valuesSystem.Console.WriteLine(a);System.Console.WriteLine(b);System.Console.WriteLine(c);System.Console.WriteLine(d);}}
As we can see in the code above, True is printed for strings whose values are the same, and False is printed for values that are not equal.
