Generate Deconstructors

Code | Generate | Deconstructors
Alt+Insert | Deconstructors

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

Before generationAfter generation
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; } }

Generate a deconstructor

  1. In the editor, set the caret at the type name or within a type at the line where you want to insert a deconstructor. If the caret is on the type name, the generated code will be added in the beginning of the type declaration.

  2. Press Alt+Insert or choose Code | Generate... from the main menu. Alternatively, you can press Ctrl+Shift+A, start typing the command name in the popup, and then choose it there.

  3. In the Generate popup, select Deconstructors.

  4. In the Generate dialog that appears, select type members that should be used in the deconstructor.

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