Serialize and Base64 convert and vice versa in vb.net - vb.net

Question

I have functions which serialize and base64 convert objects and vice versa. It uses Newtonsoft to serialize and deserialize Objects. The code works but is there a way to do this without using Newtonsoft?
Public Shared Function SerializeAndBase64(ObjectToSerialize As Object) As ReturnObject(Of String)
Dim rtnObj As New ReturnObject(Of String)
Try
Dim SerializedObjectJson As String = Newtonsoft.Json.JsonConvert.SerializeObject(ObjectToSerialize)
Dim Base64String As String = Convert.ToBase64String(Encoding.UTF8.GetBytes(SerializedObjectJson))
rtnObj.Item = Base64String
Catch ex As Exception
rtnObj.ErrorID = ErrorHandler.handleError(ex)
rtnObj.ErrorMessage = ex.Message
rtnObj.IsError = True
End Try
Return rtnObj
End Function
Public Shared Function DeserializeFromBase64(Of t)(Base64Json As String) As ReturnObject(Of t)
Dim rtnObj As New ReturnObject(Of t)
Try
Dim SerializedObjectJson As String = Encoding.UTF8.GetString(Convert.FromBase64String(Base64Json))
Dim DeserializedObject As t = Newtonsoft.Json.JsonConvert.DeserializeObject(Of t)(SerializedObjectJson)
rtnObj.Item = DeserializedObject
Catch ex As Exception
rtnObj.ErrorID = ErrorHandler.handleError(ex)
rtnObj.ErrorMessage = ex.Message
rtnObj.IsError = True
End Try
Return rtnObj
End Function
Thanks in advance.

You can Serialize/Deserialize it yourself. You just have to come up with a way to save everything into a single string, or XML or even a byte array if you want. Your choice.
Public Class Class1
Public Property MyValue As String
Public Function Serialize() As String
Return MyValue
End Function
Public Sub Deserialize(ByVal value As String)
MyValue = value
End Sub
End Class
