我正在尝试利用 Revit API 中的 ExtensibleStorage。我正在尝试将数组存储在 ArrayField 中。我想也许我的错误是由于 IronPython 接口，但也许有人成功地做到了这一点？我知道要设置的对象应该是一个 IList，但我似乎无法制作一个。在 IronPython 文档中，Array-object 被用作示例。如果我尝试这个：vl = IList[ElementId]([v.ViewId for v in views])我得到一个系统错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
SystemError: MakeGenericType on non-generic type

这是我的代码：

from System import Guid, Array
from Autodesk.Revit.DB.ExtensibleStorage import *

guid = Guid.NewGuid()
views = revit.uidoc.GetOpenUIViews()
vl = Array[ElementId]([v.ViewId for v in views])

schemaBuilder = SchemaBuilder(guid)
schemaBuilder.SetReadAccessLevel(AccessLevel.Public)
schemaBuilder.SetWriteAccessLevel(AccessLevel.Public)
schemaBuilder.SetSchemaName('Testing')
schemaBuilder.AddArrayField('Views', ElementId)
schema = schemaBuilder.Finish()

entity = Entity(schema)
entity.Set('Views', vl)

这是我的错误信息：

Exception : Autodesk.Revit.Exceptions.InvalidOperationException: Unsupported type: Autodesk.Revit.DB.ElementId[]
   at Autodesk.Revit.DB.ExtensibleStorage.Entity.Set[FieldType](String fieldName, FieldType value, ForgeTypeId unitTypeId)
   at Autodesk.Revit.DB.ExtensibleStorage.Entity.Set[FieldType](String fieldName, FieldType value)

顺便说一句：这工作正常：

from System import Guid, Array
from Autodesk.Revit.DB.ExtensibleStorage import *

guid = Guid.NewGuid()
views = revit.uidoc.GetOpenUIViews()
v = views[0].ViewId

schemaBuilder = SchemaBuilder(guid)
schemaBuilder.SetReadAccessLevel(AccessLevel.Public)
schemaBuilder.SetWriteAccessLevel(AccessLevel.Public)
schemaBuilder.SetSchemaName('Testing')
schemaBuilder.AddSimpleField('Views', ElementId)
schema = schemaBuilder.Finish()

entity = Entity(schema)
entity.Set('Views', v)

要获取值：entity.Get[ElementId]('Views')

我认为我在 c# 中使用 AddArrayField 时遇到了同样的问题，并且可能做错了什么，但我的快速修复解决方案是简单地使用 AddMapField。

    FieldBuilder mapField_Child_Angle = mySchemaBuilder.AddMapField("FurnLocations_Angle", typeof(ElementId), typeof(double));
    mapField_Child_Angle.SetUnitType(UnitType.UT_Length);

这对我有用：

from System import Guid
from System.Collections.Generic import IDictionary, Dictionary
from Autodesk.Revit.DB.ExtensibleStorage import *

keyType = str
valueType = str
name = 'UserViews'
schemaBuilder = SchemaBuilder(Guid.NewGuid())
schemaBuilder.SetReadAccessLevel(AccessLevel.Public)
schemaBuilder.SetWriteAccessLevel(AccessLevel.Public)
schemaBuilder.SetSchemaName('Test')
schemaBuilder.AddMapField(name, keyType, valueType)
schema = schemaBuilder.Finish()
ent = Entity(schema)
dic = Dictionary[str, str]()
dic.Add('kyrreViews', '234234,121345,123113')
ent.Set[IDictionary[str, str]](name, dic)
val = ent.Get[IDictionary[str, str]](name)

>>> val
Dictionary[str, str]({'kyrreViews' : '234234,121345,123113'})
