我在 MVC4 应用程序中使用 SQL Server 2008 和 EntityFramework 6。
我正在使用以下代码从数据库中获取内容。
Content content = contentBusinessObject.SelectBy(contentPredicate.Expand(),
new List<string>
{
"Tags",
"User",
"Attachments",
"Products",
"ContentEditors",
"ContentEditors.User"
});
[DataObjectMethod(DataObjectMethodType.Select)]
public TEntity SelectBy(Expression<Func<TEntity, bool>> predicate, List<string> includeNavigationProperties = null)
{
if (includeNavigationProperties == null || includeNavigationProperties.Count <= 0)
return DBSet.FirstOrDefault(predicate);
DbQuery<TEntity> query = includeNavigationProperties.Aggregate<string, DbQuery<TEntity>>(DBSet, (current, property) => current.Include(property));
return query.FirstOrDefault(predicate);
}
上面的代码生成以下 t-sql
