在C#列表中的所有字符串中删除特定的char [英] Remove specific char in all strings in a list in c#

问题描述

我在列表中有一些字符串

I have some strings in a list they are

KHIJEFGACDB
KHIJEFGBACD
KHIJEFGBCDA
KHIJEFGCDAB
KHIJEFGCDBA
KHIJGABCDEF
KHIJGABEFCD
KHIJGACDBEF
KHIJGACDEFB
KHIJGAEFBCD
KHIJGAEFCDB
KHIJGBACDEF
KHIJGBAEFCD

我需要删除列表中所有字符串中可用的HIJ.

I need to remove HIJ which is available in all strings in the list.

我制作了一个如下的C#程序

I made a C# program like below

foreach (string item in items)
{
    item.Replace("HIJ", "");
}
Console.WriteLine(items.FirstOrDefault().Length);

但是它仍然显示11，这意味着HIJ没有被删除.如何解决这个问题并得到8作为答案.

But its still displaying 11 that means the HIJ is not removed. How to solve this and get 8 as the answer.

推荐答案

字符串在C#中是不可变的.试试

Strings are immutable in C#. Try

for (int i = 0; i < items.Length; i++)
    items[i] = items[i].Replace("HIJ", "");

也请注意

foreach (string item in items)

item无法修改.而且，顺便说一句，foreach 不能用于在源集合中添加或删除项目，以避免不可预测的副作用.请参阅 http://msdn.microsoft.com/en-us/library/ttw7t8t6. aspx .

item cannot be modified. And, BTW, foreach can not be used to add or remove items from the source collection to avoid unpredictable side effects. See http://msdn.microsoft.com/en-us/library/ttw7t8t6.aspx.
