Hey all, I have need of a sort of specialized dictionary. My use case is this: The user wants to specify ranges of values (the range could be a single point as well) and assign a value to a particular range. We then want to perform a lookup using a single value as a key. If this single value occurs within one of the ranges then we w...
I am trying to merge two .net regular expressions into one. The following expressions are validating excel like cell names. Regex.IsMatch(name, @"^[A-Za-z]{1}[\w\.]*$") && !Regex.IsMatch(name, @"^[A-Za-z]{1,2}\d+$"); The first part ensures the cell name starts with a character and can be any length. The second ensures the cell na...

The new WCF services take the currently logged on domain user and pass their details through to the server so they don't need to sign on. This means all WCF services run under the context of the user acces...

I have deleted this file several times, it is not in source control, and AFAIK nobody else is tampering with the project. But...

We need to implement some general-purpose object structure, much like an object in dynamic languages, that would give us a possibility of creating the whole object graph on-the-fly. This class has to be serializable and somehow user friendly. So far we have made some experiments with class derived from Dictionary<string, object> using t...
