我正在使用C＃，我正在开发一个控制台应用程序，用于使用OMDB API获取某些电影的信息。当我输入array [i]作为电影类的标识符时，我遇到了问题。 PS：这是我的第一个问题，如果您对改进有任何反馈，请告诉我。

显然，您希望输出某些返回属性的值。因为您将JSON反序列化为对象，所以您必须使用反射，或者使用dynamic。

更好的解决方案是将JSON解析为JObject，然后使用此对象的索引：

JObject movie = JObject.Parse(getJson());
string[] array = {
                        "Title",
                        "Year",
                        "Rated",
                        "Genre",
                        "Writer",
                        "Plot"
                    };
for (int i = 0; i < array.Length; i++)
{
    Console.Write(movie[array[i]].ToString());
}
var key = Console.ReadKey();

我正在使用NuGet的Newtonsoft.Json库。

如果您想使用反射，则可以执行以下操作：

RootObject movie = new JavaScriptSerializer().Deserialize<RootObject>(getJson());
string[] array = {
                        "Title",
                        "Year",
                        "Rated",
                        "Genre",
                        "Writer",
                        "Plot"
                    };
for (int i = 0; i < array.Length; i++)
{
    var propertyInfo = movie.GetType().GetProperty(array[i]);
    Console.WriteLine(propertyInfo.GetValue(movie).ToString());
    Console.WriteLine();
}
var key = Console.ReadKey();

如何在c＃中使用数组迭代作为反序列化json RootObject的标识符？
