Azure cosmos db集合未获取分区密钥

Question

await client.CreateDatabaseIfNotExistsAsync(new Database() { Id = "data"});
DocumentCollection dCollection = await client.CreateDocumentCollectionIfNotExistsAsync(UriFactory.CreateDatabaseUri("data"), new DocumentCollection { Id = "coll"}, new RequestOptions { OfferThroughput = 400, , PartitionKey = new PartitionKey("/id") });
// dashboardCollection.PartitionKey.Paths.Add("/id");

当我转到portal.azure.com并检查我的文档数据库时，集合就创建了。当我转到集合的scale and settings时，我看不到分区键。

我手动创建了另一个集合，它在scale and settings部分中显示了分区键。

由于此分区键错误，delete函数引发错误

ResourceResponse<Document> response = await client.DeleteDocumentAsync(UriFactory.CreateDocumentUri("data", "coll", "1"), new RequestOptions { PartitionKey = new PartitionKey("1") });

我来自CosmosDB工程团队。

创建DocumentCollection时，请确保在DocumentCollection对象中提供分区键，如下所示：

PartitionKeyDefinition pkDefn = new PartitionKeyDefinition() { Paths = new Collection<string>() { "/id" } };
DocumentCollection dCollection = await client.CreateDocumentCollectionIfNotExistsAsync(UriFactory.CreateDatabaseUri("data"), new DocumentCollection { Id = "coll", PartitionKey = pkDefn }, new RequestOptions { OfferThroughput = 400, PartitionKey = new PartitionKey("/id") });

在collection CRUD请求期间，RequestOptions上的PartitionKey不会被执行，因为我们希望PartitionKey是collection对象的一部分。在文档CRUD请求期间执行RequestOptions上的PartitionKey。
