Exceptions

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 Document are:

StatusCodeReason for exception
404NotFound - This means the resource you tried to read did not exist.
429TooManyRequests - This means you have exceeded the number of request units per second. Consult the DocumentClientException.RetryAfter value to see how long you should wait before retrying this operation.

Examples


  //Reads an Offer resource from a Database
  // - offer_id is the ID of the conflict to be read
  var offerLink = "/offers/offer_id";
  Offer offer = await client.ReadOfferAsync(offerLink);

Remarks

Doing a read of a resource is the most efficient way to get a resource from the Database. If you know the resource's ID, do a read instead of a query by ID.

For an Offer, id is always generated internally by the system when the linked resource is created. id and _rid are always the same for Offer.

The format for offerLink is always "/offers/{offer identifier}"
