问题描述

我现在正在VB.net项目上工作.我是VB.Net LINQ的新手，我想知道Lambda的等效语言

I am working on a VB.net project now. I am new to VB.Net LINQ and would like to know the Lambda equivalent of

var _new = orders.Select(x => x.items > 0);

在VB.Net中.

有人建议！

推荐答案

lambda语法与创建常规委托并没有太大区别.

The lambda syntax isn't that much different than creating a regular delegate.

如果创建具有返回值的lambda，请使用Function.否则，如果创建的不是，请使用Sub.

If creating a lambda which has a return value, use Function. Otherwise if you're creating one that doesn't, use Sub.

Dim _new = orders.Select(Function(x) x.Items > 0)

Dim action As Action(Of Item) = Sub(x) Console.WriteLine(x.Items)
