locking

C#, .Net2.0, XP, Zen

I have 2 threads accessing a shared dictionary of structures, each thread via an event. At the beginning of the event I lock the dictionary, remove some structures, and exit the lock+event. Yet somehow the 2nd thread|event is finding some of the removed structures.

Conceptually I must be doing something wrong for this to be happening? I thought locking was supposed to make it thread safe?

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
