从 Glass.Mapper.Sitecore 升级到 Glass.Mapper.Sc 时缺少 InstanceContext

Question

我正在将一个项目从 Glass Mapper v2 (Glass.Mapper.Sitecore) 升级到 v4 (Glass.Mapper.Sc)，我运行遇到了一个问题，我们的解决方案是使用 InstanceContext 对象来通过模板 ID 获取 classes。我在新的 Glass Mapper 中找不到 InstanceObject 或类似的 class。这是使用它的代码片段，希望它能指出我哪里出错了。

protected InstanceContext InstanceContext;

public MappingService(ISitecoreContext context)
{
    InstanceContext = context.InstanceContext;
}

public T Map<T>(ISitecoreItem sourceItem) where T : class
{
    Type sourceType = InstanceContext.GetClassById(sourceItem.TemplateId);
    if (sourceType != null)
    {
        return Map(sourceItem, sourceType, typeof(T)) as T; 
    }

    return Mapper.Map<T>(sourceItem);
}

// The GetClassById is implemented in an extensions class like this:
public static Type GetClassById(this InstanceContext context, Guid templateId)
{
    if (context.ClassesById.ContainsKey(templateId))
    {
        SitecoreClassConfig config = context.ClassesById[templateId].FirstOrDefault();
        if (config != null)
        {
            return config.Type;
        }
    }
    return default(Type);
}

在"new"glass.mapper中可以通过查询Glass上下文对象的TypeConfigurations属性得到class

像这样：

var configs = Glass.Mapper.Context.Default.TypeConfigurations.Select(x => x.Value as SitecoreTypeConfiguration);
var types = configs.Where(x => x.TemplateId == templateId);
