        For x As Integer = 0 To fileContents.Length - 1
            If fileContents(x).Contains(ComboBox1.Text) Then
                     TextBox1.Text = fileContents(x).Substring(1, fileContents(x).IndexOf(" "))
             End If

the following code is in VB 6.0 conert to .net as desired.

Private Sub Cmdcount_Click()
List2.Clear
T2 = Trim(Text2.Text)
Open Trim(Text1.Text) For Input As #1
Do Until EOF(1)
Line Input #1, n
LNWORDCOUNT = 0
LNCOUNT = LNCOUNT + 1
T1 = n
CT = 1
Do While CT <= Len(T1)
ctr = InStr(CT, T1, T2)
If ctr <> 0 Then
CT = ctr + 1
CTR1 = CTR1 + 1
LNWORDCOUNT = LNWORDCOUNT + 1
Else
Exit Do
End If
Loop
'Print LNCOUNT & "    " & LNWORDCOUNT
If LNWORDCOUNT <> 0 Then
List2.AddItem "Line No :" & LNCOUNT & "    " & "Occurance :" & LNWORDCOUNT
End If
Loop
Label1.Caption = "Total Occurance In File : " & CTR1
Close #1

End Sub

Private Sub CmdExit_Click()
End
End Sub

Private Sub CmdOpen_Click()
Dim n As String
Dim ctr As Integer
Dim CTR1 As Integer
Dim STR As String
Dim i As Integer
Dim LNCOUNT As Integer
Dim LNWORDCOUNT As Integer
List2.Clear
Label1.Caption = ""
On Error GoTo err1
cd.DialogTitle = "Open File"
cd.InitDir = "C:\"
cd.CancelError = True
cd.ShowOpen
Text1.Text = cd.FileName
List1.Enabled = True
Exit Sub
err1:
MsgBox Err.Description

End Sub

Private Sub List1_DblClick()
Text2.Text = Trim(List1.List(List1.ListIndex))
End Sub

Private Sub Text2_Change()
Cmdcount.Enabled = Len(Text2.Text) > 0
End Sub

please ignore the unnecessary part of the code.
