Enterprise Library DAAB – ADO.NET and Stored Procedures Made Easy

using (DbConnection connection = factory.CreateConnection())

{

connection.ConnectionString = connectionString;

 

using (DbCommand selectCommand = factory.CreateCommand())

{

selectCommand.CommandType = CommandType.StoredProcedure;

selectCommand.CommandText = “SalesByCategory”;

selectCommand.Connection = connection;

 

DbParameter categoryParameter = selectCommand.CreateParameter();

categoryParameter.ParameterName = “@CategoryName”;

categoryParameter.Value = “Beverages”;

 

DbParameter yearParameter = selectCommand.CreateParameter();

yearParameter.ParameterName = “@OrdYear”;

yearParameter.Value = “1998”;

 

selectCommand.Parameters.AddRange(new[] {categoryParameter, yearParameter});

 

connection.Open();

 

using (IDataReader dr = selectCommand.ExecuteReader())

{

while (dr.Read())

Console.WriteLine(string.Format(“{0}: {1:c}”, dr[“ProductName”], dr[“TotalPurchase”]));

}

}

}

 

Compare this to using the Data Access Application Block in Enterprise Library:

 

Database db = DatabaseFactory.CreateDatabase();

 

using (IDataReader dr = db.ExecuteReader(“SalesByCategory”, “Beverages”, “1998”))

{

while (dr.Read())

Console.WriteLine(string.Format(“{0}: {1:c}”, dr[“ProductName”], dr[“TotalPurchase”]));

}
