How to use LiteDB

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"));
}

Where to use?

• Desktop/local small applications
• Application file format
• Small web applications
