DLR的应用：托管API与面向切面编程

1. DLR托管API

DLR（动态语言运行时）托管API提供了丰富的价值和功能。下面是一个使用DLR托管API运行Python代码的示例：

RemotingFactory remotingFactory = (RemotingFactory)Activator.GetObject(
typeof(RemotingFactory), "tcp://localhost:8088/RemotingFactory");

ScriptRuntime runtime = remotingFactory.GetScriptRuntime();
ScriptEngine pyEngine = runtime.GetEngine("python");
string pyFunc = @"def isodd(n): return 1 == n % 2;";
ScriptSource source = pyEngine.CreateScriptSourceFromString(pyFunc,
    SourceCodeKind.Statements);
ScriptScope scope = pyEngine.CreateScope();
source.Execute(scope);
ObjectHandle IsOddHandle = scope.GetVariableHandle("isodd");

ObjectHandle result = pyEngine.Operations.Invoke(IsOddHandle, new object[] { 3 });
bool answer = pyEngine.
