示例1: GetType
' Add the following directive to your file:
' Imports System.Linq.Expressions
' A label that is used by a break statement and a loop.
Dim breakLabel As LabelTarget = Expression.Label()
' A label that is used by the Continue statement and the loop it refers to.
Dim continueLabel As LabelTarget = Expression.Label()
' This expression represents a Continue statement.
Dim continueExpr As Expression = Expression.Continue(continueLabel)
' A variable that triggers the exit from the loop.
Dim count As ParameterExpression = Expression.Parameter(GetType(Integer))
' A loop statement.
Dim loopExpr As Expression = Expression.Loop(
Expression.Block(
Expression.IfThen(
Expression.GreaterThan(count, Expression.Constant(3)),
Expression.Break(breakLabel)
),
Expression.PreIncrementAssign(count),
Expression.Call(
Nothing,
GetType(Console).GetMethod("WriteLine", New Type() {GetType(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(Of Action(Of Integer))(loopExpr, count).Compile()(1)
輸出:
Loop Loop Loop
