c# - How to create a DTO in asp.net? -

1) want know recommended way create & return dto object has 10 attributes , want return 2 dto object.

2) should dto's have own namespace ? if yes, how organize them ? each dto inside single class file or dto's inside single class ?

please provide me sample code.

dtos dumb objects composed of public getters/setters. put them in separate namespace called someproject.dto.

public class customerdto {     public int id { get; set; }     public string name { get; set; }     public locationdto homeaddress { get; set; } } 

i try keep property names same between dto , corresponding domain class, possibly flattening. example, customer might have address object, dto might have flattened to:

public class customerdto {     public int id { get; set; }     public string name { get; set; }     public string homestreet { get; set; }     public string homecity { get; set; }     public string homeprovince { get; set; }     public string homecountry { get; set; }     public string homepostalcode { get; set; } } 

you can dramatically reduce amount of repetitive mapping code of translating domain objects dtos using jimmy bogard's automapper.
