How do I combine Generic list of different types in to one generic custom list of type?
Example:
Public class Customer
{
    long customerId{ get; set; }
    int titleId{ get; set; }
        string firstName{ get; set; }
        string middleName{ get; set; }
        int maritalStatusId { get; set; }
}

public class Address
{
        public long addressId{ get; set; }
        long customerId{ get; set; }
        short addressTypeId{ get; set; }
        string postCode{ get; set; }
        string geoCodeLattitude{ get; set; }
        string geoCodeLongitude{ get; set; }
}

public class Account
{
    long accountID{ get; set; }
        string accountDesc{ get; set; }
        short accountStatusID{ get; set; }
        DateTime joinDate{ get; set; }
        DateTime insertDateTime{ get; set; }
}

<CustomerProfile>
<Customer>
    <customerId>
    <titleId>
        <firstName>
        <middleName>
        <maritalStatusId>
</Customer>
<Address>
        <addressId>
        <customerId>
        <addressTypeId>
        <postCode>
        <geoCodeLattitude>
        <geoCodeLongitude>
</Address>
<Account>
    <accountID>
        <accountDesc>
        <accountStatusID>
        <joinDate>
        <insertDateTime>
</Account>
</CustomerProfile>

public class CustomerProfile
{
public Customer { get; set;}
public Address { get; set;}
public Account { get; set:}
}
