我有以下DataFrame模式：

root
 |-- event: struct (nullable = false)
 |    |-- code: string (nullable = true)
 |    |-- idEvent: string (nullable = true)
 |    |-- contract: struct (nullable = false)
 |    |    |-- idApplication: string (nullable = true)
 |    |-- version: struct (nullable = false)
 |    |    |-- idVersion: string (nullable = true)
 |    |    |-- entity: array (nullable = false)
 |    |    |    |-- element: struct (containsNull = false)
 |    |    |    |    |-- idEntity: string (nullable = true)
 |    |    |    |    |-- entityType: array (nullable = false)
 |    |    |    |    |    |-- element: struct (containsNull = false)
 |    |    |    |    |    |    |-- entityNumber: string (nullable = true)
 |    |    |    |    |    |    |-- entityVersion: array (nullable = false)
 |    |    |    |    |    |    |    |-- element: struct (containsNull = false)
 |    |    |    |    |    |    |    |    |-- entityCode: string (nullable = true)
 |    |    |    |    |    |    |    |    |-- idCode: string (nullable = true)

从这个模式中，我们得到了一个由单个列组成的DataFrame：event .
我希望检索位于entityVersion数组中的idCode属性。您知道是否有一种方法可以检索idCode值，而不必使用explode之类的方法来扁平化整个DataFrame吗？
非常感谢！
