My program should write hundreds of files to disk, received by external resources (network) each file is a simple document that I'm currently store it with the name of GUID in a specific folder but creating hundred files, writing, closing is a lengthy process.

Is there any better way to store these amount of files to disk? I've come to a solution, but I don't know if it is the best.

First, I create 2 files, one of them is like allocation table and the second one is a huge file storing all the content of my documents. But reading from this file would be a nightmare; maybe a memory-mapped file technique could help. Could working with 30GB or more create a problem?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
