Question

反序列化json字符串时，是否需要为字符串的每个部分设置一个属性，或者为什么字符串没有得到转换？


var webClient = new WebClient();
var json = webClient.DownloadString("https://omdb-api.now.sh/?i=tt7784604");
var movies = JsonConvert.DeserializeObject<JsonMovies>(json);
return View(movies);

public class JsonMovies
{
        public IList<MovieData> movies { get; set; }
}

public class MovieData
{
        public string Title { get; set; }
}

获取各种电影的空引用。

我从您提供的URL中获得了JSON的例子。

这将是您的C＃实体以捕获JSON：

public class Rating
{
    public string Source { get; set; }
    public string Value { get; set; }
}

public class RootObject
{
    public string Title { get; set; }
    public string Year { get; set; }
    public string Rated { get; set; }
    public string Released { get; set; }
    public string Runtime { get; set; }
    public string Genre { get; set; }
    public string Director { get; set; }
    public string Writer { get; set; }
    public string Actors { get; set; }
    public string Plot { get; set; }
    public string Language { get; set; }
    public string Country { get; set; }
    public string Awards { get; set; }
    public string Poster { get; set; }
    public List<Rating> Ratings { get; set; }
    public string Metascore { get; set; }
    public string imdbRating { get; set; }
    public string imdbVotes { get; set; }
    public string imdbID { get; set; }
    public string Type { get; set; }
    public string DVD { get; set; }
    public string BoxOffice { get; set; }
    public string Production { get; set; }
    public string Website { get; set; }
    public string Response { get; set; }
}

您要做的是基于此模型反序列化它。

using (WebClient wc = new WebClient())
{
    var json = wc.DownloadString("https://omdb-api.now.sh/?i=tt7784604");
    if (!string.IsNullOrEmpty(json))
    {
        var movies = JsonConvert.DeserializeObject<RootObject>(json);
        return View(movies);
    }
    //Json is null returns null to your view. 
    return View();
}

然后可以确定它不为空。
