比较逻辑应用中的两个版本

Question

我有两个版本字符串，我需要像 .NET Version类型那样比较它们（知道主要版本、次要版本，而不仅仅是字符串）以查看哪个更新。 我的问题是：如何检查逻辑应用程序中哪个版本字符串较新？

有没有比字符串操作的“蛮力”方法更好的方法？

major = split(variables('CurrentImageVer', '.'))[0]
minor = split(variables('CurrentImageVer', '.'))[1]

等等...

Answer 1

我同意@Skin，因为版本本身是字符串类型，这可以通过字符串操作来完成。 以下是从我这边复制后对我有用的东西。

出于演示目的，我在数组变量中使用了以下 2 个版本。

[
  "1.2.31",
  "1.2.30"
]

• 首先，我试图从数组中拆分两个版本。

  

• 然后我使用条件连接器检查版本 1 是否大于另一个。

  

结果：

下面是我的逻辑应用程序的完整 JSON。
