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

Example

Find Documents by Using Builders

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

Select the Asynchronous or Synchronous tab to see the corresponding code.

var filter = Builders<Restaurant>.Filter
    .Eq(r => r.Cuisine, "Pizza");
return await _restaurantsCollection.Find(filter).ToListAsync();

For a fully runnable example of using the Find() method to asynchronously find multiple documents, see Asynchronous Find Multiple Example.

var filter = Builders<Restaurant>.Filter
    .Eq("cuisine", "Pizza");
return _restaurantsCollection.Find(filter).ToList();

For a fully runnable example of using the Find() method to synchronously find multiple documents, see Synchronous Find Multiple Example.

Find Documents by Using LINQ

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

Select the Asynchronous or Synchronous tab to see the corresponding code.

return await _restaurantsCollection.AsQueryable()
    .Where(r => r.Cuisine == "Pizza").ToListAsync();

For a fully runnable example of using the Find() method to asynchronously find multiple documents, see Asynchronous Find Multiple Example.

return _restaurantsCollection.AsQueryable()
    .Where(r => r.Cuisine == "Pizza").ToList();

For a fully runnable example of using the Find() method to synchronously find multiple documents, see Synchronous Find Multiple Example.

Find All Documents

The following example finds all documents in the restaurants collection.

Select the Asynchronous or Synchronous tab to see the corresponding code.

var filter = Builders<Restaurant>.Filter.Empty;
return await _restaurantsCollection.Find(filter)
    .ToListAsync();

For a fully runnable example of using the Find() method to asynchronously find multiple documents, see Asynchronous Find Multiple Example.

var filter = Builders<Restaurant>.Filter.Empty;
return _restaurantsCollection.Find(filter)
    .ToList();

For a fully runnable example of using the Find() method to synchronously find multiple documents, see Synchronous Find Multiple Example.

Expected Result

Running the preceding full examples prints the following results:

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

These examples use the sample datasets provided by Atlas. The number of documents returned may differ depending on the data in your collection.
