在List<>中查找元素包含一个值 [英] Find element in List<> that contains a value

问题描述

我有一个List<MyClass> MyList其中

public class MyClass
{
    public string name { get; set; }
    public string value { get; set; }
}

给一个名字，我想得到相应的值.我目前将其实现为:

Given a name, I'd like to get the corresponding value. I have it currently implemented as:

MyList[MyList.FindIndex(item => String.Compare(item.name, "foo", 0) == 0)].value

是否有一种更清洁的方法?

Is there a cleaner way to do this?

推荐答案

都可以使用LINQ:

var value = MyList.First(item => item.name == "foo").value;

(当然，这只会找到第一个匹配项.这周围有很多选择.)

(This will just find the first match, of course. There are lots of options around this.)

或使用 Find 代替FindIndex:

var value = MyList.Find(item => item.name == "foo").value;

尽管如此，我还是强烈建议使用LINQ-如今这是一种更加惯用的方法.

I'd strongly suggest using LINQ though - it's a much more idiomatic approach these days.

(我还建议遵循.NET命名约定.)

(I'd also suggest following the .NET naming conventions.)
