Microsoft Unity. Specify A Certain Parameter In Constructor?
Oct 30, 2010
I'm using Microsoft Unity. I have an interface ICustomerService and its implementation CustomerService. I can register them for the Unity container using the following code:
container.RegisterType<ICustomerService, CustomerService>(new TransientLifetimeManager());
If CustomerService has a certain parameter in its constructor (e.g. ISomeService1), I use the following code (I need to specify SomeService1):
container.RegisterType<ICustomerService, CustomerService>(new TransientLifetimeManager(), new InjectionConstructor(new SomeService1()));
No problems here. The problem appears when CustomerService class has two parameters (not one param as in the previous example) in its constructor (e.g. ISomeService1 and ISomeService2). It works fine when I'm using the following code: container.RegisterType(new TransientLifetimeManager(), new InjectionConstructor(new SomeService1(), new SomeService2()));The problem is that I do not want specify SomeService2() for the second parameter. I want to specify only first parameter - SomeService1(). But I get the error that I need to specify none or both of parameters. How can I specify only first parameter of constructor?

Does anyone have any good examples of how to make Unity 1.2 or 2.0 work with ASP.NET WebForms?
I thought I had this figured out, but evidently I'm missing something. Now I'm getting the error; "No parameterless constructor defined for this object". I remember getting this error a couple years ago, I and just don't remember what I did.
Obviously Unity isn't working as it should because somewhere along the way I've forgotten something.
Here's some of my code:
Global.asax

im creating site with usercontrols. I have repeater, inside it is another repeater with usercontrol. My problem is passing BindedValue to usercontrol.Bindings works fine and binds the value i need but it cannot pass the value to usercontrol. When i type it manually it works, when i bind it, it passes null (!).I've tried get,set, functions (ondatabound, onload, oninit), accessing control from code with no luck. Ive read and tried to do all the google solutions but with no luck. (even with creating usercontrol inheritance)

in my implementation, I have an interface as: ICachingManager. I've got now one implementation. I also created a manager class as:
public class CachingManager
{
#region Members
private ICachingManager service;
[Code]....
In case I had one implementation, then I can easily register the CachingManager class with Unity, automatically Unity resolves and injects the ICachingManager.
In case I had more than one implementation using named types, then how can I can make use of Unity? Do I need to make use of an Abstract Factory to decide on which named type to initialize?
Is it a good idea to make use of such a composite class or use directly implementations of the interface with Abstract Factory?

I am using unity, entity framework 4 with POCO classes, repository pattern for DAL and services for Business Logic control.I also want to use Unit of Work so I can package together CRUD operations which I perform on different services and then commit them all together.My question is what would be the proper way to inject the Unit Of Work mechanism into my application using Microsoft Unity?I understand that I can put the IUnitOfWork together with the repository on the constructor of the proper service and then if Unity mapping is specified it would auto initiate the proper instances, but this way I do not pass the global unit of work but rather create a new instance on each level, which can't be a smart way to do it (actually the repository is initiated even before the service).
private IUnitOfWork _uow;
/// <summary>
/// Returns the active object context
/// </summary>
private ObjectContext ObjectContext

I would like to implement IOC and DI and have been looking at the various open source IOC's such as Unity, StructureMap, Ninject, and Castle Windsor, but I noticed that some of them are based on .Net 3.5 framework. Does this matter? Which IOC's would be most suitable or easily integrates for use in an MVC3, EF4, and .NET 4 framework application? Which would be the simplest to implement?

Im faced with an impending upgrade to an ASP.NET site and I am thinking of introducing DI using Unity. I have researched the ASP.NET DI side of things and have 2 options (Global.asax or IHttpModule). Im happy to use either. As always, there is a legacy object model in place that I would like to upgrade/change. I would like to go down the route of Constructor injection (passing in the DAO) however, each object has a mix of static and instance methods that both currently call into the DB using SqlCommand objects themselves. I want this removed to provide DB independence, therefore can anyone suggest the best way to do the DI in this case? Im open to drastic changes if they are needed.
public class ExampleClass
{
public ExampleClass(int test)
{
TestProperty = test;
}
public int TestProperty {get; set;}
public int Save()
{
// Call DB and Save

I have an ASP.NET web forms site using Master Pages. It is using Unity as my IoC container. I have created an HTTP Module to build up the container using a couple of tutorials i found online. I need the dependency injection to work for User Controls and the only way i was able to get this to work was to hook into the Pages PreInit event as can be seen from the code below.
[code]....
I also have autoeventwireup set to true on the pages and master page. Can anyone shed any light on why the events are not firing? Is my Unity http module causing this to happen by dropping the event wiring? I can get this to work no problem in a basic example with no IoC involved.

I am confused about the constructor of ObjectContext
// Summary:
// Initializes a new instance of the System.Data.Objects.ObjectContext class
// with a given connection string and entity container name.
//
// Parameters:
// connectionString:
// The connection string, which also provides access to the metadata information.
//
// defaultContainerName:
// The name of the default entity container. When the defaultContainerName is
// set through this method, the property becomes read-only.
protected ObjectContext(string connectionString, string defaultContainerName);
I am not understanding the parameters clearly.

if a class has a private constructor then it cant be instantiated. so, if i dont want my class to be instantiated and still use it, then i can make it static. what is the use of a private constructor? Also its used in singleton class, except that, is there any othe use ? (Note : The reason i am excuding the singleton case above is because I dont understand why do we need a singleton at all ? when there is a static class availble.

I have a connection string defined in my web.config like:
<connectionStrings>
<add name="LibraryConnectionString" connectionString="Server=.SQLEXPRESS3;Database=Library;Integrated Security=true" />
Well...lI do not understand why when i drag-and-drop tables into a new DataClasses dbml it does not construct a default constructor specifying the connection string. I only have constructor with params like:
public DataClassesDataContext(string connection) :
base(connection, mappingSource)
{
OnCreated();
}
I do need a default constructor for LinqDataSource..

I have a Class called Repository for accessing (Read/Write to and from) Database.The projects that require access to the database create an object of Repository and pass the connection string as a constructor parameter for the repository to work for that particular project.
I have few methods in the Repository that i want to be available only if certain connection strings are passed. I don't want them to be available if some different connection string is passed.Is there any way I can accomplish that?I have never used method header technique, if yes, how can i use it? if no, please let me know if there is any other way to achieve my goal.

What's the best way to handle exceptions that happen from within a controller's constructor?
All I can think of to do is use Application_OnError() or put a try/catch in my ControllerFactory.
Neither of these solutions seem ideal. Application_OnError is to broad - I have some non-mvc content in the site that has its own error handling. Using a try/catch block seems kinda hacky.
If I'm serving different content type -html/text/json/rss.... I would like to be able to handle the exception from within the action method instead of having to write all kinds of conditions to determine what kind of error message to serve.

I just struck upon a prime opportunity to further exhibit my MVC ignorance, by way of the following: How can one make use of a custom view model class that has parameters in the constructor? For example, a class that could intitialize various collections/properties based on an IPrincipal object passed in. I've come across several allusions to this scenario, involving a class inheriting DefaultModelBinder which overrides the CreateModel method, but have yet to find an example.
