我的asp.net mvc中有以下操作方法，它使用IPagedList显示对象列表：
public ActionResult Index(string searchTerm = "", int page = 1, string sort = "")
{
string withOutSpace = searchTerm.Trim();
ViewBag.searchTerm = searchTerm;
ViewBag.CurrentSortOrder = sort;
IPagedList<ITServer> servers = null;
int pagesize;
bool succeed = int.TryParse(System.Web.Configuration.WebConfigurationManager.AppSettings["TechPageSize"], out pagesize);
if (String.IsNullOrEmpty(sort))
{
servers = repository.AllFindServers(withOutSpace).OrderBy(a => a.Technology.PartialTag).ToPagedList(page, pagesize);}
populateViewData(servers.Select(a => a.Technology.IT360ID.Value).ToArray());
return PartialView("_PagedServerTable", servers);
}
}
action方法调用这两个存储库方法：
public IQueryable<ITServer> AllFindServers(string q,bool forautocomplete = false)
{
return from server in ITServersCore()
}
＆安培;
public IQueryable<ITServer> ITServersCore()
{
return IT.ITServers
.Include(a3 => a3.ITRack.Technology)
.Include(a3 => a3.ITRack.DataCenter)
.Include(a5 => a5.Technology)
.Include(a6 => a6.ITVirtualMachines)//nav
.Include(a11 => a11.ITServers1)//nav
.Include(a13 => a13.ITFirewalls)//nav
.Include(a14 => a14.ITSwitches)//nav
.Include(a14 => a14.ITRouters);//nav
}
但是上面将生成一个非常长的SQL语句，包含大量冗余代码（我基本上删除了生成的SQL的某些部分，因为它会超出在此处添加新问题时允许的字符数论坛!! 1）： -
