I’ve covered many valuable methods from System.Linq class library before, so you already know it’s packed with extension-method goodness. Today I’d like to cover two small families I’ve neglected to mention before: Skip() and Take(). While these methods seem so simple, they are an easy way to create sub-sequences for IEnumerable (more)

Sunday, August 28, 2011 8:46:16 PM GMT Friday, August 26, 2011 2:21:44 AM GMT
Today we will look at five easy ways to aggregate sequences.  Often times when we’re looking at a sequence of objects, we want to perform some sort of aggregation across those sequences to find a calculated result. This may involve calculating the values of the sequence or projections on those values. We will look at Sum(), Average(), Min(), Max(), and Aggregate() (more)

How to cook a loop
posted by slo2olsslo2ols 694 days, 7 hours, 58 minutes ago
Tuesday, July 26, 2011 10:43:30 AM GMT
With coming of Linq we rarely write loops. Actually, the most part of data fetching tasks, those earlier was done by loops, today could be simply done by Linq-to-Objects. Nevertheless, the loops are widely used for different scenarios and a developer should try to write a good loop. This post was written for beginners, but I hope that experienced developers will find in it something useful. (more)

In this post I am going to show how to do ordering when you require to order data by using the multiple columns. By using .Orderby(x=>x.Columnname) in the LINQ query we can easily order data of the source collection. So most of new developer make use of the same function two time .Orderby(x=>x.Columnname).Orderby(x=>x.Columnname) and thinks that will do the ordering on the multiple columns. IEnumerable (more)

As you can read in the blogpost about access jpg’s through ftp with asp.net. I have explained there how I connected with FTP and retrieved images of the IP security camera. Now I have slightly modified the LINQ so that it downloads the latest 3 images and I would like to animate the transition between them. Now I know that I can use some fancy jQuery for image transitions, but I would like to merge the three images in a Gif. (more)
