Exceptions
If either databaseLink or documentCollection is not set.
Represents a consolidation of failures that occured during async processing. Look within InnerExceptions to find the actual exception(s).
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} );
}
