Can anyone tell me how can I get the matched string in my specified pattern.

For example I used this

VB

Dim myString as String = "Hi! My name is XYZ"
Regex.IsMatch(".* My name is XYZ", myString)

Here the string will be matched. Is there any way which can say what string was matched with wildcard...

For example, In the above case Hi! will be matched with .* wildcard.. Is there any way to detect it.

Thanks in advance

Your parameters are the wrong way round - the first parameter is the string to test, and the second parameter is the regular expression to use:

VB.NET

Regex.IsMatch(myString, ".* My name is XYZ")

To retrieve the details of the match, use the Match method[^], which returns a Match object[^]. You'll also need to wrap the section you want to retrieve in a group: (.*)

VB.NET

Dim myString As String = "Hi! My name is XYZ"
Dim match As Match = Regex.Match(myString, "(.*) My name is XYZ")
If match.Success Then
    Dim matchedPart As String = match.Groups(1).Value
    ...
End If
