在LINQ中使用OrderBy添加SelectList中的位置

Question

此代码已经有效，但如何在现有LINQ中添加WHERE子句？

ViewBag.UserType= new SelectList(_odb.USR_TYP_MSTR.OrderBy(o => o.USR_TYP_ID), "USR_TYP_ID", "USR_TYP_DESC");

Answer 1

ViewBag.UserType= new SelectList(_odb.USR_TYP_MSTR.Where(o => o.USR_TYP_ID ==1 ).OrderBy(o => o.USR_TYP_ID), "USR_TYP_ID", "USR_TYP_DESC");
