Record Types

Record Types

Record types are a new feature introduced in C# 9.0 that allow you to define value types that are based on data rather than behavior. They are similar to classes, but they are immutable by default and have additional features that make them more suitable for storing data.

Record types have a number of features that make them useful for storing data:

1. Immutability: Record types are immutable by default, which means that once you create a record, you cannot change its values. This can make it easier to reason about your code and prevent accidental modification of data.
2. Deconstruction: Record types can be deconstructed into their individual fields, which makes it easier to extract and use the data they contain.
3. Equality: Record types have built-in support for value-based equality comparison, which means you can compare two record instances to see if they have the same values.
4. ToString: Record types have a built-in implementation of the ToString method that returns a string representation of the data they contain.

Here is an example of a record type in C#:

public record Person { public string FirstName { get; init; } public string LastName { get; init; } public int Age { get; init; } } var person = new Person { FirstName = "John", LastName = "Doe", Age = 30 };
