Delete Many Documents
You can delete more than one document using the DeleteMany() synchronous
method or the DeleteManyAsync() asynchronous method on a collection object.
Example
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; } [] 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; } [] public double[] Coordinates { get; set; } public string Street { get; set; } [] 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.
The following code deletes all documents in the restaurants collection whose
borough field value equals the word "Brooklyn".
Select the Asynchronous or Synchronous tab to see the corresponding code.
Expected Result
Running either of the preceding full examples prints the following results:
Deleting documents... Deleted documents: 6086 Resetting sample data...done.
