For All Properties we have to set [Serializable()] in Class

[Serializable()]
public class Person
{
  public Address Address { get; set; }
}
[Serializable()]
public class Address 
{
  public string streetName {get;set;}
  public SubAddress SubAddress{get;set;}
}

[Serializable()]
public class SubAddress
{
  public string DoorNo {get;set;}
}

In Report in the code tab of report Properties follwing code is used

 Public Function GetName(ByRef obj As Object) As String 
     If obj Is Nothing Then Return "na" 
     Else : Return obj.streetName 
     End If 
 End Function

and report field get it as =Code.GetName(Fields!Address.Value)

As you can read in this blog's post from Brian Hartman, there was a change since VS2010 for the nested class in a LocalReport.

He suggest to add the attribute [Serializable()] (if applicable).

Your class will be look like this:

[Serializable()]
public class Person
{
  public Address Address { get; set; }
}
[Serializable()]
public class Address 
{
  public string streetName {get;set;}
}

Edit: added the code after some comments. Try to implement your class like this:

[Serializable()]
public class Person
{
    private Address _address;
    public Address Address
    {
        get
        {
            if(_address == null)
                return new Address(string.Empty);
            return _address;
        }
        set
        {
            _address = value;
        }
    }
    [Serializable()]
    public class Address
    {
        private string _streetName;
        public string streetName 
        { 
            get
            {
                return _streetName;
            }
            set
            {
                _streetName = value;
            }
        }
        public Address(string streetName)
        {
            _streetName = streetName;
        }
    }
}

In this way it will always return a value and never null.
