如图：
vb.net正则表达式 替换内容
@interface不替换的话，就把正则改成：
@(?!interface)[^\s]+(\s|$)
如果@t3(synopsis = "AB") 这个等号前后没有空格，就很简单，直接用下面的搞定，如果有空格，这个正则就会复杂很多了：
Regex.Replace(@"@t1
@t2()
@t3(synopsis=""AB"")
@t4(""unused"")
creatCommChat(@WebParam(name=""chatID"") String chatID,@WebParam(name=""creatUserID"") String creatUserID)", @"@[^\s]+(\s|$)", "")
VB.NET用正则表达提取数字的问题！
你把替换所有非数字为空字符串,改为替换所有非数字为空格,就可以把每组数字分开了.
完整的程序如下(改动的地方见注释)
Dim bbb As String
bbb = TextBox1.Text
Dim My_str As String = Regex.Replace(bbb, "[^0-9]", " ") '这里把替换所有非数字为空字符串,改为替换所有非数字为空格
MsgBox(My_str)
vb.net正则表达式的写法
var reg = /;SPLIT(?:(?!;SPLIT)[\s\S])*;SPLIT/g;
var str = "";
str.replace(reg,"");
