Simple question - As I get more and more namespaces in my solution, the list of using statements at the top of my files grows longer and longer. This is especially the case in my unit tests where for each component that might be called I need to include the using for the interface, the IoC container, and the concrete type. With upward ...
I have a winform app that calls a web service to check for updates. This works in dev and it also works everywhere else I've tried it, just not on the installed copy on my machine (which happens to be the same in dev).
The error is:

When using the Net.Sockets.TcpListener, what is the best way to handle incoming connections (.AcceptSocket) in seperate threads?

Is there a standard library method that converts a string that has duration in the standard ISO 8601 Duration (also used in XSD for its duration type) format into the .NET TimeSpan object?
For example, P0DT1H0M0S which represents a duration of one hour, is converted into New TimeSpan(0,1,0,0,0).
A Reverse converter does exist which wor...
I'm about to implement a feature in our application that allows the user to 'upload' a PDF or Microsoft PowerPoint document, which the application will then make available to other users in a viewer (so they don't get to 'download' it in the 'Save as..' sense).
I already know how to save and retrieve arbitrary binary information in data...
Hessian is a custom binary serialization protocol, (which is open-source - I think), that forms the basis for a binary cross platform remoting framework. I'd like to know if anyone here has used it, and if so, what sort of performance can we expect from a solution that bridges a Java app on one side with a C# app on the other. (Let us co...

Once selected, the text cell will be populated with the full file path....
Let's say I have a web page that currently accepts a single ID value via a url parameter:
http://example.com/maypage.aspx?ID=1234
I want to change it to accept a list of ids, like this:
http://example.com/mypage.aspx?IDs=1234,4321,6789
So it's available to my code as a string via context.Request.QueryString["IDs"]. What's the ...

I seem to remember reading something about how it is bad for structs to implement interfaces in CLR via C#, but I can't seem to find anything about it. Is it bad? Are there unintended consequences of doing so?
public interface Foo { Bar GetBar(); }
public struct Fubar : Foo { public Bar GetBar() { return new Bar(); } }

I would like to do this in order to get...
Lucene has quite poor support for Russian language.
RussianAnalyzer (part of lucene-contrib) is of very low quality.
RussianStemmer module for Snowball is even worse. It does not recognize Russian text in Unicode strings, apparently assuming that some bizarre mix of Unicode and KOI8-R must be used instead.
Do you know any better solut...
In my application I have a DataGridView control that displays data for the selected object. When I select a different object (in a combobox above), I need to update the grid. Unfortunately different objects have completely different data, even different columns, so I need to clear all the existing data and columns, create new columns and...

dim b as New Foo()
and a would get a unique id and b would get a unique ID. The ids only have to be unique over run time so i would just like to use an integ...
