What is object identity in C#?

What is object identity in C#?

Object identity in C# refers to the uniqueness of an object instance in memory. Each object has a distinct identity, which is maintained even if the object's data changes.

How can I check if two objects are the same in C#?

You can check if two objects are the same by using the 'ReferenceEquals' method, which compares the references of the two objects.

What about value types? Do they have object identity?

Value types in C# do not have object identity in the same way reference types do. They are compared by their values rather than their references.

Can you give an example of object identity in a C# program?

Sure! Here's a simple example:

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

var person1 = new Person { Name = "Alice" };
var person2 = person1;

Console.WriteLine(object.ReferenceEquals(person1, person2)); // This will print 'True'
