VB.NET: Check if input in textbox is in string array

Private Sub txtQty_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtQty.GotFocus
   Dim strItem As String
   strItem = txtItem.Text
   Dim strArray As String
   strArray = itemArr(1)

   If String.Compare(strItem, strArray) = True Then
       MessageBox.Show("item in array!")
   End If
End Sub

Private Sub txtQty_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtQty.TextChanged

    If txtItem.Text <> Nothing And txtQty.Text <> Nothing Then

        'create rows in the DataTable
        tblScItem.Rows.Add(itemArray())
    End If

    txtItem.Text = ""
    txtQty.Text = ""

End Sub

This is how i declare my array:

Function itemArray() As String()

        itemArr(0) = ""
        itemArr(1) = txtItem.Text
        itemArr(2) = Form2.cbGondola.SelectedItem
        itemArr(3) = txtQty.Text
        itemArr(4) = DateTime.Now
        itemArr(5) = Form1.txtLoginId.Text

        Return itemArr
End Function

I dont seem to do a proper check, help!

The String.Compare method doesn't return a boolean, it returns an integer.

If the strings are equal, it returns 0.

If String.Compare(strItem, strArray) = 0 Then

You should set Option Strict to On in your project, so that the compiler won't allow the implicit conversion from boolean to integer.
