You Should Know:
Keeping up with the latest features in C# can be challenging, but mastering them can significantly enhance your coding efficiency. Below are some practical examples and commands to help you get started with the latest C# features.
C# 9: Records
Records provide a concise way to define immutable data types.
public record Person(string FirstName, string LastName);
Usage:
var person = new Person("John", "Doe");
Console.WriteLine(person); // Output: Person { FirstName = John, LastName = Doe }
C# 10: File-Scoped Namespaces
Simplify namespace declarations by scoping them to the entire file.
namespace MyApp;
public class Program
{
public static void Main() => Console.WriteLine("Hello, World!");
}
C# 11: Raw String Literals
Raw string literals allow for easier handling of multi-line strings without escape sequences.
string json = """
{
"name": "John",
"age": 30
}
""";
Console.WriteLine(json);
C# 12: Primary Constructors
Primary constructors streamline class initialization.
public class Person(string firstName, string lastName)
{
public string FirstName { get; } = firstName;
public string LastName { get; } = lastName;
}
C# 13: Pattern Matching Enhancements
Pattern matching continues to evolve, making code more readable and expressive.
if (obj is string { Length: > 5 } longString)
{
Console.WriteLine($"Long string: {longString}");
}
