示例1: test
' Add the following directive to your file:
' Imports System.Linq.Expressions
Dim num As Integer = 100
' This expression represents a conditional operation;
' it will evaluate the test (first expression) and
' execute the ifTrue block (second argument) if the test evaluates to true,
' or the ifFalse block (third argument) if the test evaluates to false.
Dim conditionExpr As Expression = Expression.Condition(
Expression.Constant(num > 10),
Expression.Constant("n is greater than 10"),
Expression.Constant("n is smaller than 10")
)
' Print the expression.
Console.WriteLine(conditionExpr.ToString())
' The following statement first creates an expression tree,
' then compiles it, and then executes it.
Console.WriteLine(
Expression.Lambda(Of Func(Of String))(conditionExpr).Compile()())输出：
IIF("True", "num is greater than 10", "num is smaller than 10")
num is greater than 10
