Generate Deconstructors

note

Tuple deconstruction is a C# 7.0 feature.

By default, JetBrains Rider automatically detects C# version based on the associated compiler. However, you can specify the target C# version explicitly for a project — press Alt+Enter on the project in the Solution Explorer and use the Language version selector on the Application page of the Project Properties dialog .

To set the C# version for all projects in your solution, specify it in a Directory.Build.props file in your solution directory as described here.

JetBrains Rider helps you quickly generate overloads for the Deconstruct method with selected members.

public class Version
{
    public int Major { get; }
    public int Minor { get; }
}

public class Version
{
    public int Major { get; }
    public int Minor { get; }

    public void Deconstruct(out int major, out int minor)
    {
        major = this.Major;
        minor = this.Minor;
    }
}

tip

You can configure common code generation preferences on the Editor | Members Generation page of JetBrains Rider settings Ctrl+Alt+S.

tip

You can invoke Find Usages Shift+F12 on the Deconstruct method to find all related tuple deconstructions.

JetBrains Rider also checks if a type contains the required deconstructor, and if not, suggests a quick-fix based on the tuple deconstruction.
