String Matching in LINQ(blogs.telerik.com)

submitted by jnpetrov(95) 1 month, 3 days ago

Performing simple string equality tests is often not enough when application user convenience is key. Often only a fragment of a string is known to the user, or many of them. Sometimes there is a need to search for a fragment in multiple columns. Which options does OpenAccess and LINQ provide to perform string matching? Into which SQL is the LINQ expression translated? read more...

Difference between SkipWhile and Where in linq(www.dotnetjalps.com)

submitted by jalpesh(1347) 1 month, 11 days ago

Before some time I have written a blog post about the SkipWhile operator and a reader of my blog asked me that we can do the same thing with Where also but there is a difference between this two. So In this post I am going to explain you difference between those two. Where operator filters a list of collection based on condition. It will filter whole collection while SkipWhile will only skip those elements in list until condition is true and after that it will stop filtering of skipping. Now let’s take an example where we can see the difference between Where and SkipWhile. Following is a code for that. read more...

Monadic Philosophy Part 2 – The LINQ Monad(devhawk.net)

submitted by pwhe23(972) 4 months, 22 days ago

If you don't come from a math or philosophy background (and I don't) "monad" sounds like a made-up word. Of course, understanding OO's use of terms like "class" and "object" can be hard to grok at first too. But at least those terms have some grounding in real-world concepts that non-math geeks come across. Because I couldn't draw an analogy of monads to anything at first, it made grasping the concept of monads very hard for me. read more...

NHibernate.Linq Pitfalls: Casting(notherdev.blogspot.com)

submitted by notherdev(238) 6 months, 28 days ago

One thing that needs to be always remembered when writing NHibernate.Linq queries is that it is going to be translated into SQL eventually. What this means is that we can't do everything in our Select or Where conditions - we are restricted by the capabilities of underlying database and SQL language itself. read more...

Dynamic Lambda Expression For Sorting A List / Collection Using Comple(www.jebarson.info)

submitted by jebarson007(150) 9 months, 2 days ago

In my previous post we discussed on sorting the list / collection using dynamic lambda expression for properties. In this article we will see how to sort on complex properties. So what is a complex property. Consider the class diagram as shown below In our scenario, we have “Employee” entity, where we have a property “Department” which is a complex type. Now let us assume that we are binding the list of employees list along with the department name, then we will have to use item template along with “Bind” method called. read more...

LINQ - Comparing Count() to Any()(colinmackay.co.uk)

submitted by dpeterson(4397) 9 months, 7 days ago

Compares the performance differences and considerations between using Count and Any to determine if any elements in a collection match a filter. A commenter also points out that using Any with an embedded filter gives different performance results as well. While it's important not to prematurely optimize, it is important to consider the points in this article if you write queries like this that run in a tight loop or iterate over large sets of data. read more...
