使用JSON.net

Use JSON.net

首先，创建一个像这样的类

First, create a class like this

public class FileInformation
{
    public string name{get;set;}
    [JsonProperty(PropertyName = "mime-type")]
    public string mimeType{get;set;}
    public int size {get;set;}
}

然后

var list = new List<FileInformation>();

foreach (string filename in fileNames)
{
  FileInfo fileInfo = new FileInfo(fileName);

  string actualFileName = fileInfo.Name;
  string mimeType = MimeMapping.GetMimeMapping(fileInfo.Name);
  long size = FileInfo.length;


  list.Add(new FileInformation(){//SetProperties});
}

var yourJSONString = JsonConvert.SerializeObject(list);

就这样
