在控制器中使用带有LINQ的ViewBag和SelectList在WHERE子句中添加AND（ASP.Net MVC）

Question

如何在WHERE中使用ViewBag在当前LINQ中添加第二个Controller子句（'AND'）？谢谢！

ViewBag.Subjects = new SelectList(_odb.SUBJ_MSTR.
                   Where(o => o.TYPE== "4").OrderBy(o => o.SUBJ_NAME), "SUBJ_ID", "SUBJ_VAL");

Answer 1

您可以像&&这样添加WHERE。

ViewBag.Subjects = new SelectList(_odb.SUBJ_MSTR.
                   Where(o => o.TYPE== "4" && o.TYPE=="5").OrderBy(o => o.SUBJ_NAME), "SUBJ_ID", "SUBJ_VAL");
