C# is a multi-paradigm, managed, garbage-collected, object-oriented programming language created by Microsoft in conjunction with the .NET platform. Use this tag for questions related to C#. In case a specific version of the framework is used, you could also include that tag; for instance .net-2.0.

Simple foreach adding to a list
Considering the LINQ generated from refactoring this code, I think cleaning this up might require more effort than just using LINQ.
For example, you're assigning the item directly to the model, but …

Dynamic, generic property "assignator"
I'll say it at the risk of sounding harsh--I believe the pattern of using strings and objects as generic "value-holders" but then pushing them into "generic" methods with string/object type parameters …

Refactor foreach loops
I know this question has been answered, but I feel like this is a perfect case for the SequenceEqual method. Rather than having to handle the 2 equalitycomparers in the same layer you can change your …

Create an instance (view) given its dependency (view model)
A ViewModel should not be convertible to a View, it should be bound to it. The View should have a ViewModel property. You should not have child Views for child ViewModels. Instead, you should have one …

Seemingly redundant conditionals...or not?
I'm working on some code that has the following pattern of conditionals inside it. It doesn't look great, but it doesn't look terrible.
Please, shed some light on the underlying reason this is not p …

Returning a cached contact by ID
It's debatable on which is more readable. I've worked in places where the common opinion is that an explicit else is more readable, and I've worked in places that consider the terser the code, the bet …

Automapper - Mapping a nested collection to a list
When dealing with collections, the trick is always to set up a mapping of the items in the collections and never (well, I've never seen a case that needed) a mapping from one collection to another. Th …

Validation for DTO using DataAnnotations
Not bad, but I'm not too fond of how the Validate instance method is just a call to a Validator static class passing in this. Just call the static method directly. If you're worried about the duplicat …

Using an IEnumerator without a foreach loop in order to simulate a state machine
Your code is probably not working like you think it's working. I'd bet it works the same as code that just returns booleans directly.
Consider the fact that you're creating a new enumerator every ti …

Are private extension methods a bad thing to use?
The smell here should not be whether it's private, but rather an extension method called in an extension method.
You might not even need the first two methods to be extension methods. If a fluent syn …

First time trying async
Good code for a simple example of async. The real power of async/await comes into play when you have to make service calls, query a database, or you have several things happening at the same time. I t …

Photo gallery user control
You really just need an IEnumerable of strings and not images. You could probably directly bind the results of the GetFiles method!!

Moving business logic towards the domain object as a design pattern
