A quick example for store and search documents:
// Create your POCO class
public class Customer
{
public int Id { get; set; }
public string Name { get; set; }
public string[] Phones { get; set; }
public bool IsActive { get; set; }
}
// Open database (or create if not exits)
using(var db = new LiteDatabase(@"C:\Temp\MyData.db"))
{
// Get customer collection
var col = db.GetCollection<Customer>("customers");
// Create your new customer instance
var customer = new Customer
{
Name = "John Doe",
Phones = new string[] { "8000-0000", "9000-0000" },
IsActive = true
};
// Insert new customer document (Id will be auto-incremented)
col.Insert(customer);
// Update a document inside a collection
customer.Name = "Joana Doe";
col.Update(customer);
// Index document using a document property
col.EnsureIndex(x => x.Name);
// Use Linq to query documents
var results = col.Find(x => x.Name.StartsWith("Jo"));
