在我的dbGeography linq-to-entity语句中删除radius子句

Question

如何删除linq-to-entity语句中的“半径”，以免将搜索范围限制为半径？

仅供参考-我想让我的查询搜索以'term'开头的名称，并以最靠近位置点的名称开头向外搜索，但不限于半径

DbGeography location = DbGeography.FromText("POINT(" + longitude.ToString() + " " + latitude.ToString() + ")");
            int radius = (50 * 5280); // 50 miles

            var namesList = (from N in dbContext.Profiles
                             where N.FullName.StartsWith(term) 
                             && N.LocationPoints.Distance(location) <= radius
                             orderby N.LocationPoints.Distance(location) ascending
                             select new ProfileNameSearch {
                                 label = N.FullName + " - " + N.Location,
                                 value = N.FullName,
                                 location = N.LocationPoints.Latitude.ToString() + "," + N.LocationPoints.Longitude.ToString()
                             }).Take(10).ToList();

Answer 1

只需删除行

&& N.LocationPoints.Distance（location）<=半径
