org.openrewrite.csharp.tree.Cs.DeclarationExpression

All Implemented Interfaces:

Cs, org.openrewrite.java.tree.Expression, org.openrewrite.java.tree.J, org.openrewrite.java.tree.TypedTree, org.openrewrite.Tree

Enclosing interface:

public static final class Cs.DeclarationExpression
extends Object
implements Cs, org.openrewrite.java.tree.Expression, org.openrewrite.java.tree.TypedTree

A declaration expression node represents a local variable declaration in an expression context. This is used in two primary scenarios in C#:

• Out variable declarations: Method(out int x)
• Deconstruction declarations: int (x, y) = GetPoint()

Example 1: Out variable declaration:

 if(int.TryParse(s, out int result)) {
     // use result
 }
 

Example 2: Deconstruction declaration:

 int (x, y) = point;
 ^^^^^^^^^^
 (int count, var (name, age)) = GetPersonDetails();
             ^^^^^^^^^^^^^^^ DeclarationExpression
                 ^^^^^^^^^^^ ParenthesizedVariableDesignation
  ^^^^^^^^^ DeclarationExpression
      ^^^^^ SingleVariableDesignation
