1、从数据库获取DataTable类型：

DataTable dt = DBConn.GetPageList(pageIndex, pageSize, "select * from erp_process" + pageSort, ref rowCount);

2、DataTable转换为var类型：

var query = from p in dt.AsEnumerable() 
                            select new 
                            { 
                                ID = int.Parse(p["ID"].ToString()), 
                                ProcessCode = p["ProcessCode"].ToString(), 
                                ProcessName = p["ProcessName"].ToString(), 
                                ProcessType = p["ProcessType"].ToString(), 
                                ProcessMan = p["ProcessMan"].ToString(), 
                                ProcessTypeName = TypeMapping(p["ProcessType"].ToString()), 
                                ProcessManName = ManMapping(p["ProcessMan"].ToString()) 
                            };

3、返回JsonResult类型：

Json(new { rows = query, total = rowCount }, JsonRequestBehavior.AllowGet);
