Expression::Switch Method (Expression^, Expression^, array<SwitchCase^>^)

.NET Framework (current version)

Creates a SwitchExpression that represents a switch statement that has a default case.

Namespace: System.Linq.Expressions
Assembly: System.Core (in System.Core.dll)

Syntax

public:
static SwitchExpression^ Switch(
	Expression^ switchValue,
	Expression^ defaultBody,
	... array<SwitchCase^>^ cases
)

Parameters

switchValue: Type: System.Linq.Expressions::Expression^
The value to be tested against each case.

defaultBody: Type: System.Linq.Expressions::Expression^
The result of the switch if switchValue does not match any of the cases.

cases: Type: array<System.Linq.Expressions::SwitchCase^>^
The set of cases for this switch expression.

Return Value

Type: System.Linq.Expressions::SwitchExpression^

The created SwitchExpression.

Remarks

All SwitchCase objects in a SwitchExpression object must have the same type, unless the SwitchExpression has the type void.

Each SwitchCase object has an implicit break statement, which means that there is no implicit fall through from one case label to another.

If switchValue does not match any of the cases, the default case represented by defaultBody is run.
