我在一个Silverlight应用程序中托管IronPython脚本,我想运行脚本并获取一个System.Windows.Controls.TextBlock对象。Silverlight和IronPython中的NotImplementedException
,所以我用这个代码的IronPython:
import clr
clr.AddReferenceByName("System.Windows.Controls, Version=2.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35")
from System.Windows.Controls import *
tb = TextBlock()
我被能够添加引用,但是,当我导入System.Windows.Controls我得到一个System.NotImplementedException。
同样的情况,如果我尝试“进口WPF”
我使用Silverlight 4中和IronPython 2.7.1β2 ,这是运行脚本代码:
Dim engine = IronPython.Hosting.Python.CreateEngine
Dim scope = engine.CreateScope()
Dim source = engine.CreateScriptSourceFromString(CodeTB.Text)
source.Execute(scope)
ResultLB.Items.Add(scope.GetVariable("hello"))
If scope.ContainsVariable("tb") Then
GuiStack.Children.Add(scope.GetVariable("tb"))
End If

什么方法会抛出异常? – svick
@svick source.Execute(scope) – Victor
我的意思是,最初抛出它的方法在堆栈跟踪的底部。其实,你能发布异常的整个堆栈跟踪吗? – svick
