Expression.MakeGoto(GotoExpressionKind, LabelTarget, Expression, Type) 方法
定义
创建一个 GotoExpression,它表示指定的 GotoExpressionKind 的跳转。Creates a GotoExpression representing a jump of the specified GotoExpressionKind. 也可以指定在跳转时传递给标签的值。The value passed to the label upon jumping can also be specified.

Public Shared Function MakeGoto (kind As GotoExpressionKind, target As LabelTarget, value As Expression, type As Type) As GotoExpression
参数
- kind
- GotoExpressionKind
GotoExpressionKind 的 GotoExpression。The GotoExpressionKind of the GotoExpression.
- target
- LabelTarget
LabelTarget 将跳至的 GotoExpression。The LabelTarget that the GotoExpression will jump to.
- value
- Expression
将在跳转时传递给关联标签的值。The value that will be passed to the associated label upon jumping.
返回
一个 GotoExpression,其 Kind 等于 kind,其 Target 属性设置为 target,并且其 Type 属性设置为 type,此外还有一个在跳转时将传递给目标标签的 value。A GotoExpression with Kind equal to kind, the Target property set to target, the Type property set to type, and value to be passed to the target label upon jumping.
