Saving Data to a File and Loading it from code

In this article we review how to load and save data to a file from code.

Saving the Data

var o = new Models.Orders();
var dataBytes = u.SerializeEntity(o);
u.Blb2File(dataBytes, @"c:\temp\orders.data"); 

Filter the data to be saved

var o = new Models.Orders();
-var dataBytes = u.SerializeEntity(o);
var dataBytes = u.SerializeEntity(o,o.ShipCountry.IsEqualTo("France"));
u.Blb2File(dataBytes, @"c:\temp\orders.data"); 

Using a Table Name Expression

this code shows how to export data from a table that uses a table name expression, in this case we used a separate Ordres file per year.

var o = new Models.Orders();
o.EntityName = "Orders_" + Date.Now.Year;
var dataBytes = u.SerializeEntity(o);
u.Blb2File(dataBytes, @"c:\temp\orders.data"); 

Loading the Data

var o = new Models.Orders();
var dataBytes = u.File2Blb(@"c:\temp\orders.data");
u.DeserializeEntity(o, dataBytes); 

Using System.IO instead of File2Blb

Saving

var o = new Models.Orders();
var dataBytes = u.SerializeEntity(o);
-u.Blb2File(dataBytes, @"c:\temp\orders.data");
File.WriteAllBytes(@"c:\temp\orders.data", dataBytes); 

Loading

var o = new Models.Orders();
-var dataBytes = u.File2Blb(@"c:\temp\orders.data");
var dataBytes =File.ReadAllBytes(@"c:\temp\orders.data");
u.DeserializeEntity(o, dataBytes);
