C# 从字符串中提取信息时的字符串操作问题
在将文本文件转换为CSV之前清理文本文件时，我遇到了一个操作字符串的问题。 我的文件看起来像这样 当你看到道奇·麦克道奇时，它的布局是正确的。布巴和篮子就是我遇到的问题的例子 篮子由于某种原因，当我遇到一个地址将在城市中填充的记录时，由于单元格的移动，当我将CSV转换为数据表时会出现问题。 关于Bubba记录类型的问题，我知道该怎么做 我知道这与我如何提取信息有关，只是当我遇到这些行时不知道如何修复它 下面是我编写的代码，用于获取此文本文件并将其写入CSVC# 从字符串中提取信息时的字符串操作问题,c#,string,information-extraction,C#,String,Information Extraction,在将文本文件转换为CSV之前清理文本文件时，我遇到了一个操作字符串的问题。 我的文件看起来像这样 当你看到道奇·麦克道奇时，它的布局是正确的。布巴和篮子就是我遇到的问题的例子 篮子由于某种原因，当我遇到一个地址将在城市中填充的记录时，由于单元格的移动，当我将CSV转换为数据表时会出现问题。 关于Bubba记录类型的问题，我知道该怎么做 我知道这与我如何提取信息有关，只是当我遇到这些行时不知道如何修复它 下面是我编写的代码，用于获取此文本文件并将其写入CSV public class PIADAT

tl；“但是，似乎很难不把电话和传真放在正确的栏目里——它们都被贴上了标签。@Henkholtman，我后来添加了标题，所以当我发布这个问题时，可以看到它看起来是什么样子，这更让人困惑。这是一种视觉表现，所以当我说地址如记录所示接管了这个城市时，你可以看到。我试着消除任何困惑，我是指手机：在文本文件中。你怎么把数据放错列了？
