c# - 尝试从 asp.net Web API 帖子中获取正确的 JSON 格式

Question

我需要我的响应看起来像这样（对象内的 JSON 数组）：

{"files":[
 {
"name":"3992wp_ss_20130215_0001.jpg","size":102,"url":"/Files/3992wp_ss_20130215_0001.jpg","thumbnail_url":"","de    lete_url":"/Files/3992wp_ss_20130215_0001.jpg","delete_type":"DELETE"
} 
  ]}

但我得到了这个（对象周围的 JSON 数组）：

[{"files":  
{"name":"3992wp_ss_20130215_0001.jpg","size":102,"url":"/Files/3992wp_ss_20130215_0001.jpg","thumbnail_url":"","delete_url":"/Files/3992wp_ss_20130215_0001.jpg","delete_type":"DELETE"}}
]

这是我的代码：

public IEnumerable<allFiles> Post()
{
    // read data

    List<DocFile> files = new List<DocFile>();

    DocFile file1 = new DocFile();
    file1.name = _fileName;
    file1.size = _lengh;
    file1.url = "/Files/" + _fileName;
    file1.thumbnail_url = "";
    file1.delete_url = "/Files/" + _fileName; 
    file1.delete_type = "DELETE";

    files.Add(file1);


    allFiles fileCont = new allFiles();
    fileCont.files = files;

    return fileCont;
}

public class allFiles
{
    public IEnumerable<DocFile> files { get; set; }
}

public class DocFile
{
    public string name { get; set; }
    public long size { get; set; }
    public string url { get; set; }
    public string thumbnail_url { get; set; }
    public string delete_url { get; set; }
    public string delete_type { get; set; }
}

我认为您的问题在于返回，尝试返回allFiles实例。

就像是：

public allFiles Post()
{
     //read data

    List<DocFile> files = new List<DocFile>();

    DocFile file1 = new DocFile();
    file1.name = _fileName;
    file1.size = _lengh;
    file1.url = "/Files/" + _fileName;
    file1.thumbnail_url = "";
    file1.delete_url = "/Files/" + _fileName; 
    file1.delete_type = "DELETE";

    files.Add(file1);

    allFiles fileCont = new allFiles();
    fileCont.files = files;

    return fileCont;
}
