c# - 在我的 dbGeography linq-to-entity 语句中删除半径子句

Question

如何删除我的 linq-to-entity 语句中的“半径”，以便它不会将搜索限制在半径范围内？

仅供参考 - 我希望我的查询搜索以“术语”开头的名称，并从最接近位置点的名称开始向外搜索，但不将其限制为半径

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

只需删除该行

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