Public Function CreateDocumentCollectionIfNotExistsAsync (databaseLink As String, documentCollection As DocumentCollection, Optional options As RequestOptions = Nothing) As Task(Of ResourceResponse(Of DocumentCollection))

Parameters

databaseLink

String

The link of the database to create the collection in. E.g. dbs/db_rid/.

documentCollection

DocumentCollection

The DocumentCollection object.

options

RequestOptions

(Optional) Any RequestOptions you wish to provide when creating a Collection. E.g. RequestOptions.OfferThroughput = 400.

Returns

Task<ResourceResponse<DocumentCollection>>

The DocumentCollection that was created contained within a Task object representing the service response for the asynchronous operation.

Exceptions

ArgumentNullException

If either databaseLink or documentCollection is not set.

AggregateException

Represents a consolidation of failures that occured during async processing. Look within InnerExceptions to find the actual exception(s).

DocumentClientException

This exception can encapsulate many different types of errors. To determine the specific error always look at the StatusCode property. Some common codes you may get when creating a DocumentCollection are:

StatusCode	Reason for exception
400	BadRequest - This means something was wrong with the request supplied. It is likely that an id was not supplied for the new collection.
403	Forbidden - This means you attempted to exceed your quota for collections. Contact support to have this quota increased.

Examples

using (IDocumentClient client = new DocumentClient(new Uri("service endpoint"), "auth key"))
{
    //Create a new collection with an OfferThroughput set to 10000
    //Not passing in RequestOptions.OfferThroughput will result in a collection with the default OfferThroughput set.
    DocumentCollection coll = await client.CreateDocumentCollectionIfNotExistsAsync(databaseLink,
        new DocumentCollection { Id = "My Collection" },
        new RequestOptions { OfferThroughput = 10000} );
}
