You can retrieve multiple documents from a collection by using the Find() method.

Examples

The examples on this page use the following Restaurant, Address, and GradeEntry classes as models:

public class Restaurant
{
    public ObjectId Id { get; set; }
    public string Name { get; set; }
    [BsonElement("restaurant_id")]
    public string RestaurantId { get; set; }
    public string Cuisine { get; set; }
    public Address Address { get; set; }
    public string Borough { get; set; }
    public List<GradeEntry> Grades { get; set; }
}

public class Address
{
    public string Building { get; set; }
    [BsonElement("coord")]
    public double[] Coordinates { get; set; }
    public string Street { get; set; }
    [BsonElement("zipcode")]
    public string ZipCode { get; set; }
}

public class GradeEntry
{
    public DateTime Date { get; set; }
    public string Grade { get; set; }
    public float Score { get; set; }
}

Note

The documents in the restaurants collection use the camel-case naming convention. The examples in this guide use a ConventionPack to deserialize the fields in the collection into Pascal case and map them to the properties in the Restaurant class.

To learn more about custom serialization, see Custom Serialization.

Find Documents Using Builders

The following example uses Builders to find documents in the restaurants collection with the cuisine "Pizza".

Finding documents with builders...:
Number of documents found: 1163
Finding documents with LINQ...:
Number of documents found: 1163
Finding all documents...:
Number of documents found: 25359

Tip

Sample Datasets
