Examples

The example below creates a new partitioned collection with 50000 Request-per-Unit throughput. The partition key is the first level 'country' property in all the documents within this collection.

DocumentCollection collection = await client.CreateDocumentCollectionAsync(
    databaseLink,
    new DocumentCollection 
    { 
        Id = "MyCollection",
        PartitionKey = new PartitionKeyDefinition
        {
            Paths = new Collection<string> { "/country" }
        }
    }, 
    new RequestOptions { OfferThroughput = 50000} ).Result;

The example below creates a new collection with OfferThroughput set to 10000.

DocumentCollection collection = await client.CreateDocumentCollectionAsync(
    databaseLink,
    new DocumentCollection { Id = "MyCollection" }, 
    new RequestOptions { OfferThroughput = 10000} ).Result;

The example below creates a new collection with a custom indexing policy.

DocumentCollection collectionSpec = new DocumentCollection { Id ="MyCollection" };
collectionSpec.IndexingPolicy.Automatic = true;
collectionSpec.IndexingPolicy.IndexingMode = IndexingMode.Consistent;
collection = await client.CreateDocumentCollectionAsync(database.SelfLink, collectionSpec);

The example below creates a document of type Book inside this collection.

Document doc = await client.CreateDocumentAsync(collection.SelfLink, new Book { Title = "War and Peace" });

The example below queries for a Database by Id to retrieve the SelfLink.

using Microsoft.Azure.Documents.Linq;
DocumentCollection collection = client.CreateDocumentCollectionQuery(databaseLink).Where(c => c.Id == "myColl").AsEnumerable().FirstOrDefault();
string collectionLink = collection.SelfLink;

The example below deletes this collection.

await client.DeleteDocumentCollectionAsync(collection.SelfLink);

Remarks

A database may contain zero or more named collections and each collection consists of zero or more JSON documents. Being schema-free, the documents in a collection do not need to share the same structure or fields. Since collections are application resources, they can be authorized using either the master key or resource keys. Refer to for more details on collections.
