Question

以下是我的代码

Dim ATT As String = "Hi Sample $1$ Text"
Dim newText As String = "<ss>Hello How Are you</ss>"
newText = Regex.Replace(newText, "<ss>(.*?)</ss>", ATT, RegexOptions.IgnoreCase)

以上代码将ATT变量中的字符串内容（“$ 1 $”）视为Regex值并将其替换为newText变量，如何克服这一点，请指导，

有没有像我们在下面提到的perl中可用的东西来克服这个问题，

$_=~ s/<ss>(.*?)</ss>/\Q$ATT\E/g;

您可以在替换字符串中escape $个字符：

Dim ATT As String = "Hi Sample $1$ Text"
ATT = ATT.Replace("$", "$$")
Dim newText As String = "<ss>Hello How Are you</ss>"
newText = Regex.Replace(newText, "<ss>(.*?)</ss>", ATT, RegexOptions.IgnoreCase)

或者使用lambda进行替换：

Dim ATT As String = "Hi Sample $1$ Text"
Dim newText As String = "<ss>Hello How Are you</ss>"
newText = Regex.Replace(newText, "<ss>(.*?)</ss>", Function(m) ATT, RegexOptions.IgnoreCase)

如何使用RegEx替换克服替换字符串错误
