How do I compare objects in C#?

In C#, you can compare objects using the Equals method or the == operator. Would you like to see examples?

Yes, please provide examples of both methods.

Sure! For the Equals method, you can override it in your class. For example:

public class Person {
    public string Name { get; set; }
    public int Age { get; set; }

    public override bool Equals(object obj) {
        if (obj is Person other) {
            return this.Name == other.Name && this.Age == other.Age;
        }
        return false;
    }
}

And for the == operator, you can overload it like this:

public static bool operator ==(Person p1, Person p2) {
    return p1.Equals(p2);
}

What about comparing lists of objects?

To compare lists of objects, you can use LINQ's SequenceEqual method, which checks if two sequences are equal. Here's an example:

List<Person> list1 = new List<Person> { new Person { Name = "Alice", Age = 30 } };
List<Person> list2 = new List<Person> { new Person { Name = "Alice", Age = 30 } };

bool areEqual = list1.SequenceEqual(list2);

This will return true if both lists contain the same elements in the same order.
