如何从字符串生成器中删除数据 [英] How to remove data from string builder

问题描述

大家好，我都需要从文本文件中删除特定数据.我已经编写了一些代码来删除我的确切数据，但是现在我有点困惑，因为删除特定数据可以帮助任何人.

最初，这是我存储在Stringbuilder中的文本文件中的数据

Hi i all having a requirement to delete particular data from a text file. I have written some code to get my exact data to remove but now i am little bit confused in removing that particular data can any one help me.

Initially this is my data in text file where i am storing to a Stringbuilder

现在通过使用某些代码，我正在删除数据，即假设我想从存在的5到8中删除.我将其存储到另一个StringBuilder，如下所示

Now by using certain code i am getting the data to delete i.e assume i would like to delete from 5 to 8 which exists. I am storing this to another StringBuilder as follows

6281110000251                00000000011              1                     1 0111000020000002

822500000100111000020000000000010000000000001                                  111000020000002

我想从我拥有的主要Stringbuilder中删除它.这是正确的过程，还是有更好的方法让我知道?

I would like to remove this from the main Stringbuilder i am having. Is this the correct process or if any better way let me know

推荐答案

您可以尝试使用第二个StringBuilder的内容，通过以下方式将其从第一个StringBuilder中删除使用替换 [

You could try using the content of the second StringBuilder to remove it from the first one by using the Replace[^] method.

It would look something like:

mainStringBuilder.Replace(anotherStringBuilder.ToString(), "");

是的-从StringBuilder中删除应该比创建一个新的效率更高.如果您知道第一个字符索引和长度(显然可以从总长度和字符索引中得出)，则可以使用StringBuilder.Remove方法 [

Yes - deleting from a StringBuilder should be a lot more efficient that creating a new one. If you know the first character index and the length (which you can obviously work out from the total length and the character index) then you can just use the StringBuilder.Remove method[^]
