C#从对象列表中删除对象 [英] C# Remove object from list of objects

问题描述

我有一个对象列表，我试图通过首先检查对象中的属性来删除列表中的特定对象.

I have a list of objects and I am trying to remove a specific object in the list by first checking a property in the object.

最初，我使用了 foreach ，但是后来意识到您不能在修改集合时使用它，所以我决定使用普通的 for ，但后来我没有使用确定如何编写与我最初编写的代码相同的代码.

Originally I used a foreach but then realised you can't use this while modifying a collection, so I decided to use a normal for but then I'm not sure how to write code that does what I originally wrote.

我该如何编写代码以完成原来的工作?

How do I go about writing code to do what I originally had?

谢谢

这是我的代码:

    public void DeleteChunk(int ChunkID)
    {
        //foreach (Chunk i in ChunkList)
        //{
        //    if (i.UniqueID == ChunkID)
        //    {
        //        ChunkList.Remove(i);
        //    }
        //}

        //This won't work because here i is just an integer so i.UniqueID won't exist.
        for (int i = 0; i < ChunkList.Capacity; i++)
        {
            if (i.UniqueID == ChunkID)
            {
                ChunkList.Remove(i);
            }
        }

    }

推荐答案

您可以使用linq简化此操作:

You can simplify this with linq:

var item = ChunkList.SingleOrDefault(x => x.UniqueId == ChunkID);
if (item != null)
    ChunkList.Remove(item);

您还可以执行以下操作，如果有多个匹配项，则也可以使用:

You can also do the following, which will also work if there is more than one match:

ChunkList.RemoveAll(x => x.UniqueId == ChunkID);
