推荐答案

您不能从文本文件中删除 - 您必须创建一个新文件，从开始到删除点复制数据，跳过已删除的部分，然后将文件的其余部分复制到结束。然后将原始文件重命名为.BAK或类似名称，并将副本重命名为原始文件名。



但是...看起来像一个INI文件，它们是严重过时了。除非这是遗留数据，否则您可能不应该使用INI格式，因为有许多更好，更现代的格式。如果您必须处理它们，可以使用 WritePrivateProfileStruct [ ^ ]删除部分，它将为您完成所有这些。

You can't "delete" from a text file - you have to create a new file, copy the data from the start up to the point of deletion, skip the deleted part, then copy the rest of the file up to the end. Then rename the original as .BAK or similar, and rename the copy to the original file name.

But...that looks like an INI file, and they are seriously outdated. Unless this is legacy data, you probably shouldn't be using INI format as there are a lot of better, more modern formats. If you must process them though, you can use WritePrivateProfileStruct[^] to delete sections and it will do all that for you.
