c sharp if string equals
// There are two ways to check if 2 strings are the same:
string str1 = "Hello";
string str2 = "Hello";

str1 == str2; // Output: true
// The second is using the 'Equals()' function
str1.Equals(str2); // Output: truec# .equals vs ==
string s1 = "test";
string s2 = "test";
string s3 = "test1".Substring(0, 4);
object s4 = s3;
Console.WriteLine($"{object.ReferenceEquals(s1, s2)} {s1 == s2} {s1.Equals(s2)}");
Console.WriteLine($"{object.ReferenceEquals(s1, s3)} {s1 == s3} {s1.Equals(s3)}");
Console.WriteLine($"{object.ReferenceEquals(s1, s4)} {s1 == s4} {s1.Equals(s4)}");
