我正在尝试向我的C#应用程序添加插件体系结构。我选择IronScheme作为语言,并且因为它建立在DLR上,所以它更易于嵌入。在C#应用程序中嵌入IronScheme
在Codeplex Wiki上,他们有following example。 我改变了它稍微:
public class PluggerInner
{
IScriptEngine scheme;
public PluggerInner()
{
InitScheme();
}
private void InitScheme()
{
var domMgr = ScriptDomainManager.CurrentManager;
var schemePrv = new IronSchemeLanguageProvider(domMgr);
scheme = schemePrv.GetEngine();
}
public void RunSchemePlugin(string fileName)
{
scheme.ExecuteFile(fileName);
}
public void RunPlugins()
{
foreach (var fl in new DirectoryInfo("../../plugins").GetFiles())
{
if (fl.Extension == ".ss")
{
RunSchemePlugin(fl.FullName);
}
}
}
}
(这基本上是执行为new PluggerInner().RunPlugins()
)
它发现我的例子.ss
文件中的目录(是的,我知道我不应该使用../..
),而是抛出一个大规模错误在这条线:
scheme.ExecuteFile(fileName);
我得到的例外是:

我的例子Scheme代码:
(define (test) (+ 1 1))
我不知道什么异常实际上是在谈论,因为它没有的InnerException。
我对方案一无所知,但是对于DLR,您是否使用ScriptEninge.Execute方法验证了基本脚本的工作原理?这就是我从IronRuby开始的地方。 – sipwiz
我现在就试试吧......谢谢! :) –
它很奇怪;我可以'engine.Execute(“(+ 1 1)”)没有例外,但是当我添加几行来使用WinForms时,它会停止。 –
