推荐答案
您必须阅读文件并 parse 其行，以便提取有意义的信息(给您看).在Regex类文档 [
You have to read the file and parse its lines in order to extract meaningful (to you) info (have a look at Regex class documentation[^]).
如果要替换:之前的每一行的内容，则可以使用以下代码
If you mean to replace the content of each line before:then the following code can be used
Dim infos As String() = System.IO.File.ReadAllLines("TextFile.vcf")
Dim modifiedInfos As String() = infos.[Select](Function(ln) _
If(ln.Contains(":"C), ln.Substring(ln.IndexOf(":"C) + 1), ln)).ToArray()
System.IO.File.WriteAllLines("modTextFile.vcf", modifiedInfos)
'Output for the info given in the question
'VCard
'2.1
