Question

I am looking for example code that provides a unit test to serialize and deserialize an object from a memory stream. I have found examples using C# 2.0, however my current project uses VB.NET 1.1 (don’t ask me why…), so the solution can not use generics. I am also using the NUnit framework for the unit tests.

Thanks!

This is the pattern I’ve settled upon:

<Test()> _
Public Sub SerializationTest()
    Dim obj As New MySerializableObject()
    'Perform additional construction as necessary

    Dim obj2 As MySerializableObject
    Dim formatter As New BinaryFormatter
    Dim memoryStream As New MemoryStream()

    'Run through serialization process
    formatter.Serialize(memoryStream, obj)
    memoryStream.Seek(0, SeekOrigin.Begin)
    obj2 = DirectCast(formatter.Deserialize(memoryStream), MySerializableObject)

    'Test for equality using Assert methods
    Assert.AreEqual(obj.Property1, obj.Property1)
    'etc...
End Sub
