Answer 1

I took a little of this and that and came up with this:

    Imports System.Reflection

Public Class ObjectHelper

    ' Creates a copy of an object
    Public Shared Function GetCopy(Of SourceType As {Class, New})(ByVal Source As SourceType) As SourceType

        Dim ReturnValue As New SourceType
        Dim sourceProperties() As PropertyInfo = Source.GetType().GetProperties()

        For Each sourceProp As PropertyInfo In sourceProperties
            sourceProp.SetValue(ReturnValue, sourceProp.GetValue(Source, Nothing), Nothing)
        Next
        Return ReturnValue
    End Function
End Class

Answer 2

I use the following:

<Extension>
Public Sub CopyPropertiesByName(Of T1, T2)(dest As T1, src As T2)

  Dim srcProps = src.GetType().GetProperties()
  Dim destProps = dest.GetType().GetProperties()

  For Each loSrcProp In srcProps
    If loSrcProp.CanRead Then
      Dim loDestProp = destProps.FirstOrDefault(Function(x) x.Name = loSrcProp.Name)
      If loDestProp IsNot Nothing AndAlso loDestProp.CanWrite Then
        Dim loVal = loSrcProp.GetValue(src, Nothing)
        loDestProp.SetValue(dest, loVal, Nothing)
      End If
    End If
  Next
End Sub
