Continue(LabelTarget)

Source:

GotoExpression.cs

continue 문을 나타내는 GotoExpression을 만듭니다.

public:
 static System::Linq::Expressions::GotoExpression ^ Continue(System::Linq::Expressions::LabelTarget ^ target);

public static System.Linq.Expressions.GotoExpression Continue (System.Linq.Expressions.LabelTarget target);

static member Continue : System.Linq.Expressions.LabelTarget -> System.Linq.Expressions.GotoExpression

Public Shared Function Continue (target As LabelTarget) As GotoExpression

매개 변수

target

LabelTarget

LabelTarget이 이동할 GotoExpression입니다.

반환

GotoExpression

GotoExpression가 Continue이고, Kind 속성이 Target으로 설정되며, 이동 시 대상 레이블에 null 값이 전달되는 target입니다.

예제

다음 예제에서는 메서드를 사용하는 Continue 루프 식을 만드는 방법을 보여 줍니다.

// Add the following directive to your file:
// using System.Linq.Expressions;

// A label that is used by a break statement and a loop.
LabelTarget breakLabel = Expression.Label();

// A label that is used by the Continue statement and the loop it refers to.
LabelTarget continueLabel = Expression.Label();

// This expression represents a Continue statement.
Expression continueExpr = Expression.Continue(continueLabel);

// A variable that triggers the exit from the loop.
ParameterExpression count = Expression.Parameter(typeof(int));

// A loop statement.
Expression loopExpr = Expression.Loop(
    Expression.Block(
        Expression.IfThen(
            Expression.GreaterThan(count, Expression.Constant(3)),
            Expression.Break(breakLabel)
        ),
        Expression.PreIncrementAssign(count),
        Expression.Call(
                    null,
                    typeof(Console).GetMethod("WriteLine", new Type[] { typeof(String) }),
                    Expression.Constant("Loop")
                ),
        continueExpr,
        Expression.PreDecrementAssign(count)
    ),
    breakLabel,
    continueLabel
);

// The following statement first creates an expression tree,
// then compiles it, and then runs it.
// Without the Continue statement, the loop would go on forever.
Expression.Lambda<Action<int>>(loopExpr, count).Compile()(1);

// This code example produces the following output:
//
// Loop
// Loop
// Loop
