示例1: Func
'Add the following directive to your file:
' Imports System.Linq.Expressions
Dim num As Double = 5.5
' This expression represents an increment operation.
Dim incrementExpr As Expression = Expression.Increment(
Expression.Constant(num)
)
' Print the expression.
Console.WriteLine(incrementExpr.ToString())
' The following statement first creates an expression tree,
' then compiles it, and then executes it.
Console.WriteLine(Expression.Lambda(Of Func(Of Double))(incrementExpr).Compile()())
' The value of the variable did not change,
' because the expression is functional.
Console.WriteLine("object: " & num)
输出:
Increment(5.5) 6.5 object: 5.5
