LINQ

Computed Properties and Entity Framework (Revisited)

Another way to use your computed properties in predicates and projections.

Since publishing my first post on the topic over a year ago, I've continued to look for easy ways to tackle this problem. In the last post, I ended up recommending the excellent DelegateDecompiler library to help convert plain unmapped properties to expression trees that LINQ to Entities can use. I still like this approach, but I've also been searching for a way to make this process a little more transparent and use a little less magic.

Streaming LINQ-Based Text Search and Replace

I was recently thinking about streaming operations and got to wondering about string operations on streaming data. Specifically, how would you perform a text search and replace on a string if you could only stream the string one character at a time? This could have real-world application in asynchronous systems where you get a string a character at a time, or in memory-intensive scenarios where you can't load the source string into memory at once. For the most part though, this was just a thought exercise. I structured the code as a LINQ-like extension method, though obviously the same approach could be used with streams.

Computed Properties and Entity Framework

How to use your computed properties in predicates and projections.

If you're using an ORM, it's not uncommon to have computed properties in addition to the ones that are stored directly in the database. Unfortunatly, these computed properties don't work with Entity Framework out of the box. In this post I'm going to discuss the problem and suggest various ways of mitigating it.
