c# - 无法通过 sdk 从 cosmos db 中删除特定文档？

Question

我按照下面的代码使用DeleteDocumentAsync。

 public static void DeleteErrorLog(List<string> LogID, string collectionName)
        {
            FeedOptions queryOptions = new FeedOptions { EnableCrossPartitionQuery = true };
            try
            {
                //getting resource id for a document with given logid

                var db = client.CreateDatabaseQuery().Where(x => x.Id == databaseName).ToList().First();
                var coll = client.CreateDocumentCollectionQuery(db.SelfLink).Where(x => x.Id == collectionName).ToList().First();
                var docs = client.CreateDocumentQuery(coll.SelfLink, queryOptions).Where(x => x.Id == LogID[0]).AsEnumerable().Single();
                var collectionUri = UriFactory.CreateDocumentUri(databaseName, collectionName, docs.ResourceId);
                client.DeleteDocumentAsync(collectionUri);

            }
            catch (Exception) { throw; }
        }

每个值都正确填充，我收到需要删除的文档但仍无法删除它？非常感谢任何帮助

您可能缺少用于删除操作的 PartitionKey:

var documentUri = UriFactory.CreateDocumentUri(databaseName, collectionName, LogID[0]);
client.DeleteDocumentAsync(documentUri, new RequestOptions(){PartitionKey=new PartitionKey(LogID[0])}).GetAwaiter().GetResult();

此外，如果您已经知道 Id(在您的情况下为 LogID[0])，则不需要查询。
