// just use the connection string name
IDBHelper dbHelper = new SqlHelper("MyCN");
// use different provider class based on your database.

Basic ADO.NET methods:

// Create parameters
var paramResultOut = DbHelper.CreateOutParameter("@Result", SqlDbType.NVarChar, 100);
var paramIsActive = DbHelper.CreateParameter("@IsActive", isActive);
var paramId = DbHelper.CreateParameter("@Id", id);

  
// ExecuteNonQuery
// Stored procedure
var count = _dbHelper.ExecuteNonQuery("DeleteCountry", paramIsActive, paramResultOut);
// OR
// Raw sql commnad
var count = _dbHelper.ExecuteNonQuery("DELETE FROM [dbo].[Country] WHERE Id = @Id", CommandType.Text, paramIsActive);


// ExecuteScalar - returning a object type scalar value 
var name = _dbHelper.ExecuteScalar("SELECT Name FROM COUNTRY");


// DataReader

var dataReader = _dbHelper.ExecuteReder("GetCountries", paramIsActive, paramResultOut);
// OR

var dataReader = _dbHelper.ExecuteReder("SELECT * FROM Country WHERE IsActive = @IsActive", CommandType.Text, paramIsActive);


// DataTable

var dataTable = _dbHelper.GetDataTable("GetCountries", paramIsActive, paramResultOut);
// OR
