List. Find. What is wrong with my code?

Hi,

I just created a predicate class following some articles there is an
error.

Could you please, tell me, what might be going on?

1 Public Class FindRowByName
2
3 Private _RowName As String
4 Public Property RowName() As String
5 Get
6 Return _RowName
7 End Get
8 Set(ByVal value As String)
9 _RowName = value
10 End Set
11 End Property ' RowName
12
13 Public Sub New(ByVal rowName As String)
14 Me.RowName = rowName
15 End Sub ' New
16
17 Public Function Search(ByVal row As BoxRows.Row) As Boolean
18 Return String.Compare(row.Name, Me.RowName)
19 End Function ' Search
20
21 End Class ' FindRowByName

I am using it as follows:

1 Dim p As New FindRowByName("Hello")
2 Dim result As Boolean = rows.Find(p.Search)

On line 2 I get the message:

"Argurment not specified for parameter row ..."

But in all examples the parameter is not passed.

Any idea?

Thanks,

What kind of collection is it that you are trying to search in? What is
the type of the rows variable?
