C# Class structure for WCF DataContract -

how implement following c# class structure used in wcf service? structure in document class created. it's person class can have multiple occurances i'm having problem with.

item - class

identifier - class (member of item)

• field1 (int)
• field2 (string)

details - class (member of item)

• detail1 (int)
• detail2 (string)
• ...

persons - class (member of item)

person - class (can have 1 200 occurances)

• info2 (string)

i have following far , not sure need complete:

[datacontract] public class item {     public class identifier     {         [datamember]         public int field1;          [datamember]         public string field2;     }      public class details     {         [datamember]         public int detail1;          [datamember]         public string detail2;     }      public class persons     {         public class person         {          }     } } 

by nesting declaration of class within class there's no instance of created, somehow magically. declaring data wcf contract isn't anyhow different—except respective attribute decorations—from declaring other data structures. hence looking this:

[datacontract] public class identifier { … }  [datacontract] public class details { … }  [datacontract] public class person { … }  [datacontract] public class item {     [datamember]     public identifier id { get; set; }      [datamember]     public details details { get; set; }      [datamember]     public list<person> persons { get; set; } }
