[RESOLVED] Small help needed with this regex

[akhileshbc]

Hi...

I want to extract mark1=90 from the string mark1=90 For English3 & English2. And I tried the following code. But it doesn't seems to be working because it is returning blank value
BTW, I'm not good in RegEX.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim strTemp As String
 
        strTemp = "mark1=90 For English"
 
        Dim aa As New System.Text.RegularExpressions.Regex("^[0-9]+$")
 
        MessageBox.Show(aa.Match(strTemp).Value)
 
    End Sub

Any help would be great... Thanks...
