ServiceId.UniqueId最大长度和格式 [英] ServiceId.UniqueId Maximum Length and Format

问题描述

每个 Item (例如 Task )在Exchange Web服务(EWS)托管API中，其Id属性的类型为 UniqueId (继承自

Every Item (e.g. Task) in Exchange Web Services (EWS) Managed API has an Id property of type ItemId, which then has a String property named UniqueId (inherited from ServiceId — phew, got that?).

我打算将<​​c5>的值保留在数据库中，所以我需要知道列的最大长度应该是多少.一些测试表明，它的长度至少为152个字节，但看起来好像是一个奇怪的最大值.

I'm planning to keep the value of UniqueId in a database so I need to know what the maximum length of the column should be. Some testing shows that it's at least 152 bytes in length, but that seems like a strange size for a maximum.

该问题的第二部分是值的格式.可以将其解析为更常见的类型吗，例如 Guid ?我知道我在抓稻草.

A second part to this question is the format of the value. Is this something that can be parsed into a more common type, like a Guid? I'm grasping at straws, I know.

推荐答案

为了安全起见，我们建议

To be safe, we've suggested setting aside 512 characters for the EWS identifier. While I don't expect that it will ever be lengthened to near 512 characters, Microsoft reserves the right to change the format. I highly doubt Exchange will change the format at this point.

关于标识符的格式-它旨在为不透明的，因此不应进行解析或重构.

Regarding the format of the identifier -- it is intended to be opaque and so it should be neither parsed nor reconstructed.
