is there way to fix the exception without removing the parameter i added to the class

var classObject = new ClassObject();

var classObject = new ClassObject(myParameterValue);

public classObject(SomeClass parameterName)
   {
   ...

public classObject()
   {
   ...

var classObject = new ClassObject(parameterValue);
dictionary.Add(id, new MemoryStream());
///then add the object stream here to the created storage on the dictionary

var retriveObject = dictionary[id] as ClassObject; //The runtime error while happen here

    Dictionary<int, MemoryStream> dictionary = new Dictionary<int, MemoryStream>();
    var classObject = new ClassObject("hello");
    int id = 666;
    dictionary.Add(id, new MemoryStream());
    var retriveObject = dictionary[id] as ClassObject;
    }


public class ClassObject : MemoryStream
    {
    public ClassObject(string s) { }
    }

[Serializable]
public class ClassObject : MemoryStream
{
    //Must be present for serialization to work!
    internal ClassObject() { }

    public ClassObject(string s) { }
}
