如何从 Silverlight 5 执行 IronPython 脚本文件

Question

我正在尝试在 silverlight 中执行 ironpython 脚本文件，但出现异常

序列不包含匹配元素

string importScript = "import sys" + Environment.NewLine +
        "sys.path.append( r"{0}" )" + Environment.NewLine +
        "from {1} import *";
        // python script to load
        string fullPath = @"c:pathmyModule.py";
        var engine = Python.CreateEngine();
        ScriptScope scope = engine.CreateScope();
        // import the module
        string scriptStr = string.Format(importScript,Path.GetDirectoryName(fullPath),Path.GetFileNameWithoutExtension(fullPath));
        var importSrc = engine.CreateScriptSourceFromString(scriptStr, Microsoft.Scripting.SourceCodeKind.File);
        importSrc.Execute(scope);
        // now you ca execute one-line expressions on the scope e.g.
        string expr = "functionOfMyModule()";
        var result = engine.Execute(expr, scope);`

首先在这里创建范围...喜欢这个

public static ScriptScope GetModule()
    {
        var pyfile = "PythonFunction.py";
        ScriptEngine engine = new ScriptRuntime(DynamicEngine.CreateRuntimeSetup(true)).GetEngine("IronPython");
        var code = new XapVirtualFilesystem().GetFileContents(pyfile);
        ScriptScope scope = engine.CreateScope();
        ScriptSource script = engine.CreateScriptSourceFromString(code, pyfile);
        script.Execute(scope);
        return scope;
    }

在所需的位置调用此方法

Python 文件遵循 PythonFunction.py

导入 CLRCLR.AddReference（"System.Windows"）从系统.视窗导入应用程序

str=Application.Current.RootVisual.FindName（"textBox2"）.发短信

def hello（str）： 打印"你好"+ str + "！欢迎来到IronPython！" 返回"索姆形态铁蟒"

Application.Current.RootVisual.FindName("textBox1").Text=hello(Application.Current.RootVisual.FindName("textBox2").Text)
