如何在有条件的情况下使用RemoveAll删除列表中的多个项目? [英] How to Remove multiple items in List using RemoveAll on condition?

问题描述

我想像下面那样

MyList.RemoveAll(t => t.Name == "ABS");
MyList.RemoveAll(t => t.Name == "XYZ");
MyList.RemoveAll(t => t.Name == "APO");

相反，我该怎么做:

MyList.RemoveAll(t => t.Name == "ABS" || t => t.Name == "XYZ" ||t => t.Name == "APO");

推荐答案

您只需要一个 lambda表达式-||就在其中:

You only need one lambda expression - the || goes within that:

MyList.RemoveAll(t => t.Name == "ABS" || t.Name == "XYZ" || t.Name == "APO");

换句话说，给出t，如果t.Name是ABS，或者t.Name是XYZ，或者t.Name是APO，我想删除该元素."

In other words, "Given a t, I want to remove the element if t.Name is ABS, or if t.Name is XYZ, or if t.Name is APO."

其中只有一个给定t"，这是t =>部分有效的意思.

There's only one "given a t" in there, which is what the t => part means, effectively.
