# New in C# 7.0: Part 4 - Expression-Bodied Members

This week, we’re discussing Expression-Bodied Members in C# 7.0. Now, this was an existing feature in C# 6.0, but it was limited to only methods, like so:

public void DoAThingCS6() => Console.WriteLine("This is a test");


With the new additions in C# 7.0, we can now do Constructors, Deconstructors, and Properties. A Constructor definition looks like this:

public SomeClass() => DoAThing();


Similarly, a Deconstructor looks like this:

~SomeClass() => DoAThing();


Finally, although auto-properties are shorter, you can write properties with specific implementations with this new shorthand:

private string someField;
public string SomeProperty
{
get => someField;
set => someField = value;
}


That’s it for this week. Next week, we’ll go over Pattern Matching.
