how to create custom properties in web service classes such as

    Public Property ClientName() As String
        Get
           Return m_strMyVal
        End Get
        Set(ByVal Value As SqlConnection)
            m_strMyVal = Value
        End Set
    End Property

please help on this

What is your goal? Thats kind of a vague question. Usually you create web methods, and you pass your arguments to those methods. If you want to create a property, you must make that property the member of some class. If you then want to pass that class on to a web method, the class must be set up to be serializable to XML.
