Ironpython使用C#對象的筆記

1. 

#List類型的定義

from System.Collections.Generic import List, Dictionary

int_list = List[int]()

#同樣Byte類型的值的定義
from System import Byte
b = Byte(1)   #

2.

C# lambada

>>> from System.Collections.Generic import IEnumerable, List

>>> list = List[int]([1, 2, 3])

>>> import clr

>>> clr.AddReference("System.Core")

>>> from System.Linq import Enumerable

>>> Enumerable.Any(list,lambda x:x<2)

True

>>> Enumerable.Any(list,lambda x:x>2)

True

>>> Enumerable.Any(list,lambda x:x>4)

False

3. C#中的byte[]數組,在Ironpython中這樣表示
from System import Array,Byte
bbyte = Array[Byte]  

4. ref 和 out

>>> from System.Collections.Generic import Dictionary

>>> d = { "a":100.1, "b":200.2, "c":300.3 }

>>> d = Dictionary[str, float](d)

>>> d.TryGetValue("b")

(True, 200.2)

>>> import clr

>>> r = clr.Reference[float]()

>>> d.TryGetValue("b", r)

True

>>> r.Value

200.2

>>>
