带where子句的foreach循环 [英] foreach loop with a where clause

问题描述

我想知道是否有可能在C#中使用where循环创建一个foreach循环.不是在其中包含if语句，而是在声明循环时使用and子句.

I was wondering if it's possible to create a foreach loop in C# with a where loop. Not with a if statement inside, but and where clause in the declaring of the loop.

也许是这样吗?

foreach(var n in people where n.sex == male)
{
}

推荐答案

是的，有可能:

方法语法:

foreach (var person in people.Where(n => n.sex == "male"))
{
}

或者相当冗长的查询语法:

Or the rather lengthy Query Syntax:

foreach (var person in from person in people where person.sex == "male" select person)
