Question

I face a problem when I try to get value from primary table in my mapping file.

My tables:

CREATE TABLE Customer (     [CustomerId] INT PRIMARY KEY,     [FullName] NVARCHAR(50) NOT NULL )  CREATE TABLE CustomerOrder (     [CustomerOrderId] INT PRIMARY KEY,     [CustomerId] INT,     [TransactionDate] DATETIME ) 

My classes:

public class CustomerOrder {     public class Id {get; set;}     public class CustomerName {get; set;}     public class TransactionDate {get; set;} } ... 

How can I get FullName value and map to CustomerName property in my CustomerOrder fluent interface mapping class?

Answer 1

You wouldn’t, really. A better design would be to have a Customer property, which is an instance of a Customer class.

public class CustomerOrder {   public int Id { get; set; }   public Customer Customer { get; set; } }  public class CustomerOrderMap : ClassMap<CustomerOrder> {   public CustomerOrderMap()   {     Id(x => x.Id);     References(x => x.Customer);   } } 

Which you can then use like so:

customerOrder.Customer.FullName 

If you really want to have a CustomerName property, you could create a delegating property on CustomerOrder.

public string CustomerName {   get { return Customer.FullName; } }
