试图让 VB.NET 调用 IronPython 来增加 VB 变量

Question

无法让 VB 调用 IronPython 到 return 递增整数。值 returned 与传递给 IronPython 的值相同。

我希望我的 VB.NET windows 表单应用程序将变量 123 传递给 IronPython，让 IronPython 将变量加 10，然后让 VB 取回它。但是，它仍然返回 123.

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
