我有一个字串
我有一字串,这个字是由AAAA .... BBBBB
中间为任意字串
我要把中间的字串换成CCCC
比如 AAAA BBDDFEFEDF BBBBB other word
AAAA BBDDFEessefFefEDF BBBBB other word2
-->希望结果 AAAA CCCC BBBBB other word
这样

Dim s As String = ...
s = Regex.Replace(s, "(?<=AAAA).*?(?=BBBBB)", "CCCC")
忽略大小写
Imports System.Text.RegularExpressions
Module Module1
Sub Main()
Dim s As String = "AAaA BBDDFEessefFefEDF BBBBB other word2"
s = Regex.Replace(s, "(?i)(?<=AAAA).*?(?=BBBBB)", "CCCC")
Console.WriteLine(s)
End Sub
