LINQ also provides with itself important aggregate function. Aggregate function are function that are applied over a sequence like and return only one value like Average, count, sum, Maximum etc…
Below are some of the Aggregate functions provided with LINQ and example of their implementation.

While working with data most of the time we have to work with relation between different lists of data. Many a times we want to fetch data from both the list at once. This requires us to make different kind of joins between the lists of data.

Visual studio 2010 has been released to RTM a few days back. This release of Visual studio 2010 comes with a big number of improvements on many fronts. In this post I will try and point out some of the major improvements in Visual Studio 2010.

LINQ is also very useful when it comes to generation of range or repetition of data.  We can generate a range of data with the help of the range method.

While working with data it’s not always required that we fetch all the records. Many a times we only need to fetch the first record, or some records in some index, in the record set. With LINQ we can get the desired record very easily with the help of the provided element operators.

LINQ has a habit of returning things as IEnumerable. But we have all been working with so many other format of lists like array ilist, dictionary etc that most of the time after having the result set we want to get them converted to one of our known format. For this reason LINQ has come up with helper method which can convert the result set in the desired format. Below is an example

There are many set operation that are required to be performed while working with any kind of data. This can be done very easily with the help of LINQ methods available for this functionality. Below are some of the examples of the set operation with LINQ.
