pythonnet clr 操作 skcomapi 範例

pythonnet_clr_skcomapi_demp.py

# 使用 pythonnet 呼叫群益api 
import clr
# AddReference，不用加副檔名 .dll
clr.AddReference(r"C:\skcom\CapitalAPI_2.13.41\x64\SKCOMLib") # 使用絕對路徑我個人偏好這個

# 加入參考後，利用 improt SKCOMLib 可以使用群益整個 skcomapi 的功能，
import SKCOMLib
# 也可以 from SKCOMlib import 部分功能
