Crear un elemento en Tridion 2011 utilizando Core Service

Question

En Tridion 2011 quiero usar el servicio central equivalente de UpdateXml para crear nuevos objetos Tridion de forma genérica. Tengo la intención de crear nuevos Componentes, Páginas y más tarde en Carpetas y Grupos de Estructura. Funciona bastante bien con UpdateXml, pero tengo un problema al convertir el RepositoryLocalObject (u otro objeto de tipo genérico) a un objeto ComponentData con el servicio principal. Mi código de Core Service es mucho más largo (y crece por segundo).

mensaje

error cuando intento acceder on-tipo de objeto propiedad específica:

Error 9 'Tridion.ContentManager.CoreService.Client.RepositoryLocalObjectData' no contiene una definición de 'contenido' y ningún método de extensión 'contenido' aceptar un primer argumento de tipo 'Tridion.ContentManager.CoreService.Client.RepositoryLocalObjectData'

¿una posible solución es crear un método de extensión?

Tridion TOM API:

Function CreateNewItemCopy(organizationalItemUri, itemType, title, xml, 
          directory, filename) 
    Dim newItem : set newItem = tdse.GetNewObject(itemType, organizationalItemUri) 
    newItem.UpdateXml(xml) 
    newItem.Title = title 

    if(itemType = 64) then ' page 
     newItem.FileName = filename 
    elseif(itemType = 4) then ' sg 
     newItem.Directory = directory 
    end if 

    newItem.save(true) 
    CreateNewItemCopy = newItem.id 
    set newItem = nothing 
End Function

* código actualizado gracias al excelente respuesta continuación

private ItemType GetTridionItemType(RepositoryLocalObjectData source) 
{ 
    string itemType = source.GetType().Name; 
    switch (itemType) 
    { 
     case "ComponentData": 
      return ItemType.Component; 
     case "PageData": 
      return ItemType.Page; 
    } 
    return ItemType.UnknownByClient; 
}

           string filename) 
{ 
    ItemType tridionItemType = GetTridionItemType(source); 
    string orgItemUri = source.LocationInfo.OrganizationalItem.IdRef; 
    var newItem = client.Copy(source.Id, orgItemUri, true, new ReadOptions()); 
    newItem.Title = title; 
    if (tridionItemType == ItemType.Page) 
    { 
     PageData pageData = newItem as PageData; 
     pageData.FileName = filename; 
     client.Update(pageData, new ReadOptions()); 
    } 
    else

    return newItem.Id;

me han ajustado ligeramente su código y ahora se está trabajando:

private string CreateNewItemCopy(string title, RepositoryLocalObjectData source, string filename) 
    { 
     string newItemUri = ""; 
     try 
     { 
      ItemType tridionItemType = GetTridionItemType(source); 
      string orgItemUri = source.LocationInfo.OrganizationalItem.IdRef; 

      if (tridionItemType == ItemType.Component) 
      { 
       ComponentData sourceComp = source as ComponentData; 
       ComponentData newComponent = client.GetDefaultData(tridionItemType, orgItemUri) as ComponentData; 
       newComponent.Title = title; 
       newComponent.Metadata = source.Metadata; 

       // ** Only Component has .Content and SchemaRef 
       newComponent.Content = sourceComp.Content; 
       newComponent.Schema.IdRef = sourceComp.Schema.IdRef; 
       newItemUri = client.Create(newComponent, new ReadOptions()).Id; 
      } 
      else if (tridionItemType == ItemType.Page) 
      { 
       PageData sourcePage = source as PageData; 
       PageData newPage = client.GetDefaultData(tridionItemType, orgItemUri) as PageData; 
       newPage.Title = title; 
       newPage.Metadata = source.Metadata; 

       // ** Only Page has .Filename 
       newPage.FileName = filename; 
       newItemUri = client.Create(newPage, new ReadOptions()).Id; 
      } 
      else //I would really like to handle all things here - but have problems with item-specific mandatory properties, such as Schema, Filename, and Dir 
      { 
       var newGenericTridionItem = client.GetDefaultData(tridionItemType, orgItemUri) as RepositoryLocalObjectData; 
       newGenericTridionItem.Title = title; 
       newGenericTridionItem.Metadata = source.Metadata; 
       //if(GetTridionItemType(newGenericTridionItem.Id) == ItemType.Page) 
       // newGenericTridionItem.filename; 
       newItemUri = client.Create(newGenericTridionItem, new ReadOptions()).Id; 
      } 
     } 
     catch (Exception ex) 
     { 
      throw; 
     } 

     return newItemUri; 
    } 

    private ItemType GetTridionItemType(RepositoryLocalObjectData source) 
    { 
     string itemType = source.GetType().Name; 
     switch (itemType) 
     { 
      case "ComponentData": 
       return ItemType.Component; 
      case "PageData": 
       return ItemType.Page; 
     } 
     return ItemType.UnknownByClient; 
    } 

Pero sigo sin entender por qué quiere hacerlo de esta manera y no utilizar el método de copia simple?
