C# 使用C和cosmos客户端从cosmos数据库中删除文档

我是Cosmos DB的新手，在阅读了microsoft文档后，我试图从Cosmos DB中删除记录。我已经尽可能地模仿这个例子。正在查找和读取该记录，但在尝试删除时遇到“未找到”错误

集合是分区的，我在示例中提到了分区键，但仍然会导致错误

    private async Task QueryItemsAsync()
    {
        var sqlQueryText = "SELECT * FROM c WHERE c.tenantId = '5c6cb2d77c1c2edc001b9007' and c.id = 'abae8abf-5836-464f-8129-1f0e83a1f639'";

        QueryDefinition queryDefinition = new QueryDefinition(sqlQueryText);
        FeedIterator<Order> queryResultSetIterator = this.container.GetItemQueryIterator<Order>(queryDefinition);

        List<Order> orders = new List<Order>();

        while (queryResultSetIterator.HasMoreResults)
        {
            FeedResponse<Order> currentResultSet = await queryResultSetIterator.ReadNextAsync();
            foreach (Order o in currentResultSet)
            {
                orders.Add(o);
                Console.WriteLine("\tRead {0}\n", o);       
            }
        }
    }         
    private async Task DeleteFamilyItemAsync()
    {
        var partitionKeyValue = "tenantId";
        var orderId = "abae8abf-5836-464f-8129-1f0e83a1f639";

        // Delete an item. Note we must provide the partition key value and id of the item to delete
        ItemResponse<Order> orderResponse = await this.container.DeleteItemAsync<Order>(orderId, new PartitionKey(partitionKeyValue));
        Console.WriteLine("Deleted Family [{0},{1}]\n", partitionKeyValue, orderId);
    }

如下图所示，正在读取该记录，因此正在查找该记录，但当我尝试删除该记录时，该记录并未被删除。 读取{Id:null，patientId:null，orchestrationId:null，预订单号：88557ec1-dccb-4397-9ce4-20b6aeb1d636，cartId:adc463ef-7f38-4fa8-8f37-e505db3a5134，确认号：QDQ-9244014-14708，cartConfirmationNum:IBM-8622967-14079，国家代码：null，类型：订单，取消日期：null，Id:abae8abf-5836-464f-8129-1f0e83a1f639}}

发生NotFound错误：CosmosRequestException；StatusCode=NotFound；子状态代码=0；ActivityId=6dd52d23-68c8-4e6d-b4ff-70cd2a6921cf；请求费用=1.24；消息=响应状态代码不表示成功：404子状态：0原因：。； 演示结束后，按任意键退出。

问题在于您的partitionKeyValue。您提供的是分区键定义，而不是值。该值是实际的租户id，而不是文本tenantId

然后，您的删除代码应如下所示：

private async Task DeleteFamilyItemAsync()
{
    var partitionKeyValue = "5c6cb2d77c1c2edc001b9007"; // <-- This is the change
    var orderId = "abae8abf-5836-464f-8129-1f0e83a1f639";

    // Delete an item. Note we must provide the partition key value and id of the item to delete
    ItemResponse<Order> orderResponse = await this.container.DeleteItemAsync<Order>(orderId, new PartitionKey(partitionKeyValue));
    Console.WriteLine("Deleted Family [{0},{1}]\n", partitionKeyValue, orderId);
}

我试着按照这个例子做一个T。你试着在data explorer上执行查询并得到结果了吗？我试着按照这个例子做一个T。你试着在data explorer上执行查询并得到结果了吗？谢谢你，尼克，我能够删除它。谢谢你，尼克，我能够删除它。
