下面红色代码位置， string result ="123456";
能正常返回值
我通过 JsHelper js = new JsHelper();
string result = js.EvalMethod(JsD, Ff, Cc);
这个在活字格插件里面返回的是错误Object reference not set to an instance of an object.
请教大神我要怎么改，

JsHelper js = new JsHelper();
string result = js.EvalMethod(JsD, Ff, Cc);
dataContext.Parameters[NewParameter] = result ;
return new ExecuteResult();
}
