示例1: Func
' Add the following directive to your file:
' Imports System.Linq.Expressions
' This expression performs a logical AND operation
' on its two arguments, but if the first argument is false,
' the second argument is not evaluated.
' Both arguments must be of the Boolean type.
Dim andAlsoExpr As Expression = Expression.AndAlso(
Expression.Constant(False),
Expression.Constant(True)
)
' Print the expression.
Console.WriteLine(andAlsoExpr.ToString())
' The following statement first creates an expression tree,
' then compiles it, and then executes it.
Console.WriteLine(Expression.Lambda(Of Func(Of Boolean))(andAlsoExpr).Compile()())输出：
(False AndAlso True) False
