VB.NETでVB変数をインクリメントするためにIronPythonを呼び出そうとする

Question

VBによって呼び出され、増分された整数を返すためのIronPythonを取得できません。 返される値は、IronPythonに渡される値と同じです。

変数123をIronPythonに渡し、IronPythonに変数を10個追加してVBでそれを取得させたいと思っています。 しかし、それはまだ123に戻ります。

Public Class Form1 
    Private Sub Button_GO_Click(sender As Object, e As EventArgs) Handles Button_GO.Click 
     ' HELLO WORLD... 
     ' bring up an IronPython runtime 
     dim engine = Python.CreateEngine() 
     dim scope = engine.CreateScope() 

     ' create a source tree from code ' 
     dim source = engine.CreateScriptSourceFromString("print 'hello from python'") 
     ' run the script in the IronPython runtime' 
     source.Execute(scope) 

     ' MODIFY VARIABLE: BUG: returns 1 instead of 11' 
     engine = Python.CreateEngine() 
     scope = engine.CreateScope() 

     ' create a Python variable "i" with the value 1'    
     scope.SetVariable("i", 1) 

     ' this script will simply add 1 to it ' 
     source = engine.CreateScriptSourceFromString("i += 10") 

     ' pull the value back out of IronPython and display it:' 
     dim response = scope.GetVariable("i") 
     debug.print( response) 
    End Sub 
End Class

私はそれを修正しました。見よ....

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load 
    ' VB SENDS A VARIABLE TO IRONPYTHON, WHICH INCS AND RETURNS IT......    http://www.chrisumbel.com/article/scripting_ironpython_dlr

     dim engine = Python.CreateEngine() 
     dim scope = engine.CreateScope() 




     ' create a Python variable "i" with the value 1   
     scope.SetVariable("i", 123) 



     ' this script will simply add 1 to it 
     dim source = engine.CreateScriptSourceFromString("i += 10") 

     '/* run the script in the IronPython runtime */ 
     source.Execute(scope) 


     '  /* pull the value back out of IronPython and display it */ 
      Console.WriteLine(scope.GetVariable("i").ToString()) 

End Sub
