Dapper Generic Repository And Unit Of Work

Instalation

Last Release: Version 1.1.0 (September 27, 2017)

PM> Install-Package Hurdad.DataAccess.DapRepo

Usage

Create models:

public class Person
{
    [Key]
    public int Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public int Age { get; set; }
    [Ignore]
    public string FullName => $"{FirstName} {LastName}";
}

Create repository:

class PersonRepository : GenericRepository<Person>
{
    public PersonRepository(IDbConnection dbConnection) : base(dbConnection)
    {
    }
}

Create unit-of-work class:

class AppUnitOfWork : UnitOfWork
{
    public UnitOfWork(bool isTransactional = false,
        IsolationLevel isolationLevel = IsolationLevel.ReadCommitted,
        int transactionTimeoutInSecond = 300,
        TransactionScopeOption transactionScopeOption = TransactionScopeOption.Required) 
        :base(isTransactional, isolationLevel, transactionTimeoutInSecond, transactionScopeOption)
    {
    }

    protected override IDbConnection CreateConnection()
    {
        var connection = new System.Data.SqlClient.SqlConnection(connectionString: ConfigurationManager.ConnectionStrings["constr"].ConnectionString);
        return connection;
    }

    private PersonRepository _personRepository;
    public PersonRepository PersonRepository => _personRepository ?? (_personRepository = new PersonRepository(this.DbConnection));
}

Then you can use instance of Unit-of-work class in your project:

using (var uow = new UnitOfWork(isTransactional: true))
{
    uow.PersonRepository.Insert(person);
    uow.CommitTransaction();

    persons.AddRange(uow.PersonRepository.GetAll());
}
