And then read data from MS Access database. First make connection string for your MS Access Database.

Now you need to write code in server side to bind GridView gvArticle. All changes will be applied or if something fails, all changes will be reverted: _(owner) This is a good practice because now we can, for example, add two owners, modify two accounts and delete one owner, all in one method, and then just call the Save method once. Public RepositoryWrapper(Repositor圜ontext repositor圜ontext)Īs you can see, we are creating properties that will expose the concrete repositories and also we have the Save() method that we can use after all the modifications are finished on a certain object. _account = new AccountRepository(_repoContext) _owner = new OwnerRepository(_repoContext) Public class RepositoryWrapper : IRepositoryWrapper Let’s start by creating a new interface in the Contract project: namespace ContractsĪfter that, we are going to add a new class to the Repository project: using Contracts Now, with that wrappers instance, we may call any repository class we need. Then place it into the IOC and finally inject it inside the controller’s constructor. Having that in mind, let’s create a wrapper around our repository user classes. Maybe it’s not a problem when we have only two classes, but what if we need logic from 5 different classes or even more. We would need to instantiate OwnerRepository and AccountRepository classes and then call the FindAll and FindB圜ondition methods. Let’s imagine if inside a controller we need to collect all the Owners and to collect only the certain Accounts (for example Domestic ones).

But there are still more things to be done. Public AccountRepository(Repositor圜ontext repositor圜ontext)Īfter these steps, we are finished with creating the repository and repository user classes. Public class AccountRepository : RepositoryBase, IAccountRepository Public OwnerRepository(Repositor圜ontext repositor圜ontext) ASP.NET allows the following sources of data to be accessed and used: Databases (e.g. Public class OwnerRepository : RepositoryBase, IOwnerRepository Now, let’s create a repository user classes in the Repository project: using Contracts Public interface IAccountRepository : IRepositoryBase Wanna join Code Maze Team, help us produce more awesome. As soon as we do this, we can delete the Entities reference from the main project because it is now provided through the Repository project that already has the Contracts project referenced, with the Entities reference inside. Let’s create interfaces in the Contracts project for our Owner and Account classes.ĭon’t forget to add a reference from the Entities project to the Contracts project. This way, we are separating the logic, that is common for all our repository user classes and also specific for every user class itself. Furthermore, by inheriting from the RepositoryBase class they will have access to all the methods from the RepositoryBase. Every user class will have its own interface, for additional model-specific methods. Now that we have the RepositoryBase class, let’s create the user classes that will inherit this abstract class. The user signs in with an external service, such as Facebook, Microsoft, or Google. When the user logs in, the ASP.NET Identity system verifies the password.

The app stores the password hash in the membership database. T hat means we don’t have to specify the exact model (class) right now for the RepositoryBase to work with, we are going to do that later on. The user registers at the site, entering a username and password. This type T gives even more reusability to the RepositoryBase class. This abstract class, as well as IRepositoryBase interface, uses generic type T to work with. Public void Delete(T entity) => Repositor圜ontext.Set().Remove(entity)

Public void Update(T entity) => Repositor圜ontext.Set().Update(entity) The code listings on this page demonstrate how to retrieve data from a database by using the following ADO.NET technologies: ADO. Public void Create(T entity) => Repositor圜ontext.Set().Add(entity) To connect to a database using a data source control, you do the following: Determine the type of data source control you need. Repositor圜ontext.Set().Where(expression).AsNoTracking() NET Core for processing data stored in MS Access DB, we have the option to use EntityFramework or ODBC.

In order to be able to work with the program to read/write Microsoft Access Database using. Public IQueryable FindB圜ondition(Expression> expression) => Interacting with MS Access Database (DB) has been a bit of challenge with. Public IQueryable FindAll() => Repositor圜ontext.Set().AsNoTracking() Public RepositoryBase(Repositor圜ontext repositor圜ontext)
