c# - 更新 Azure 表存储中的 RowKey 或 PartitionKey

Question

我可以更新 Azure 表存储中实体的 RowKey 或 PartitionKey 属性吗？

我认为是的，或者可能只是 PartitionKey，但现在我正在尝试这样做(尝试更改 RowKey 或 PartitionKey)并收到错误:

The remote server returned an error: (404) Not Found.
Description: An unhandled exception occurred during the execution of the current 
             web request. Please review the stack trace for more information about 
             the error and where it originated in the code.

Exception Details: System.Net.WebException: The remote server returned an error:
                  (404) Not Found.

Line 146:            }
Line 147:        }

我的更新实体的代码(简短版本):

var query = new TableQuery<CalculatorAccessTokenEntity>()
                .Where(TableQuery.GenerateFilterCondition("AccessUrl", 
                                                           QueryComparisons.Equal, url));

var newToken = GetUniqueKey(5);//get some random string of length 5
entity.PartitionKey = newToken;

// Try to use Merge here also but unsuccessful
var updateOperation = TableOperation.Replace(entity);    _table.Execute(updateOperation);

不可以，您无法更新实体的 PartitionKey 或 RowKey。您需要做的是执行 2 个操作:首先删除具有现有 PartitionKey/RowKey 的实体，然后插入具有新 PartitionKey/RowKey 的新实体。
