generics - C# - Is it possible to pass a derived type from a BaseModel to a Repository<T> that needs the type? -

so have repository class needs type.

i have basemodel class other models derived from.

right have have new repository() call save, update, delete, etc.

i able incorporate methods basemodel, can create object , call myobject.save(); call create repository , use it.

so this:

public class repository<t> {     public void save(t entity)     {         // save here!     } }  public class basemodel {     public string id { get; set; }     public datetime created { get; set; }      public void save()     {         // line needs type t. how pass this?         using(var repository = new repository<t>()) {             repository.save(this);         }     } }  public class derivedmodel : basemodel {     public string name { get; set; } } 

note: not using entity framework.

so result of

var myentity = new derivedmodel() {      name = "my entity"; };  myentity.save(); 

if don't want use reflection create repository, use derived type type parameter base class, example:

public class basemodel<t> // t derived type {     public string id { get; set; }     public datetime created { get; set; }      public void save()     {         // t derived type         using(var repository = new repository<t>()) {             repository.save(this);         }     } }  public class repository<t> {     // save method must use base type here     public void save(basemodel<t> item )     {      } }  // basemodel derived type type parameter public class derivedmodel : basemodel<derivedmodel> {     public string name { get; set; } }
