The snippets below illustrate Parallel LINQ in C# by crawling a web page in parallel. The Crawler class is responsible for crawling a web page (only one level deep) and returning a list of documents. The Document class represents an HTML document.
Also extended C# LINQ and Extension method (simple) to include the last (MAX) Date Created property, added a new Folder class (model) with properties and included them in a List. Also, amended the LINQ statement to get the MAX(Date Created) .
There are tons of functions out there to calculate the distance between two points, but what if you know one point and want to calculate the latitude (“vertical”) or longitude (“horizontal”) equivalent of a fixed distance, in miles? An example application would be in generating a minimum & maximum latitude and longitude bounding box around an area to limit the results of a database query that uses distance from a fixed point.
