Question

在Tridion 2011中，我想使用与UpdateXml相当的Core Service以通用方式创建新的Tridion对象。我打算在文件夹和结构组上创建新的组件，页面和更高版本。使用UpdateXml可以很好地工作但是我在使用核心服务将RepositoryLocalObject（或另一个泛型类型对象）转换为ComponentData对象时遇到问题。我的核心服务代码更长（并且在第二代增长）。

尝试访问特定于对象类型的属性时出现错误消息：

错误9'Tridion.ContentManager.CoreService.Client.RepositoryLocalObjectData'不包含'Content'的定义，也没有扩展方法'Content'接受'Tridion.ContentManager.CoreService.Client.RepositoryLocalObjectData'类型的第一个参数< / p>

可能的解决方案是创建扩展方法吗？

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

            return ItemType.Component;
        case "PageData":
            return ItemType.Page;
    }
    return ItemType.UnknownByClient;
} 

private string CreateNewItemCopy(string title, RepositoryLocalObjectData source, 
                                 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

        client.Update(newItem, new ReadOptions());

    return newItem.Id;

我稍微调整了你的代码，现在它正在运行：

    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;
    }

但是我仍然不明白你为什么要这样做，而不是使用简单的Copy方法？
