出现“索引超出范围"在C#中的List.Add()错误 [英] Got "Index out of bounds" Error on List.Add() in c#

问题描述

这是代码

List<string> something = new List<string>();
Parallel.ForEach(anotherList, r =>
     {
            .. do some work
             something.Add(somedata);
      });

每百次运行大约1次，我得到 Index out of bounds 错误.反正有什么方法可以防止由线程引起的冲突(我认为)?

I get the Index out of bounds error around 1 time per hundred run. Is there anyway to prevent the conflict (I assume) caused by threading?

推荐答案

为了防止出现此问题，您可以使用

In order to prevent the issue, instead of List you may use ConcurrentQueue or similar Concurrent collections in your parallel part. Once the parallel task is done, you can put it in the List<T>.

有关更多信息，请查看System.Collections.Concurrent命名空间，以找到适合您的用例的集合.

For more information take a look at System.Collections.Concurrent namespace to find the suitable collection for your use case.
