C#: Could not load file or assembly

As you may know, I’ve recently tweaked someone’s C# code to make it work the way I want.  That post can be found here.  I am pleased to say that it work perfectly on my laptop but when I loaded it on the server to be executed, I got the error:

Deleting Files using SQL CLR

I don’t know if I mentioned this or not but I have a SQL 2005 instance that has over 260 databases. A few weeks back, I wrote a store procedure to backup all the databases every Sunday.

Not only that, this is just 1/5 SQL instances running on one server.

C# : delete files after xx days

The key to this section is the .Skip(x).FirstOrDefault(); statement.

Finding Prime number with Lambda Expression

The other day, a co-worker showed me some C# code that included Lambdas Expression and I read it some other books as well. I scoffed at it because who need all that confusing syntax?! Well I sat down the other day and thought it over and it was pretty damn cool. The syntax might be confusing as heck, at first, but if you managed to get use it to it, it can shorten length code.

I decided to take it upon myself to learn more about Lambda along with it’s expression and statement block. I decided to start out easy, writing a short program that will find the prime number from an array.
