我试图在读取后将C＃中具有ToList的json文件转换为C＃，然后将其传递给我的模型并将其添加到db。现在，我的问题是：我该怎么做？
这是我的杰森：

我的帖子模型课：
[Table("Post")]
public partial class Post
{
[Key]
public int Id { get; set; }
[Required]
[Display(Name = "Title")]
[StringLength(150)]
public string Name { get; set; }
[AllowHtml]
[Display(Name = "Description")]
[Column(TypeName = "text")]
public string Description { get; set; }
[Display(Name = "External Image")]
[Required]
[StringLength(200)]
public string ExternalImage { get; set; }
[Display(Name = "Author")]
[StringLength(150)]
public string CreatedBy { get; set; }
[Display(Name = "Size")]
[StringLength(150)]
public string Size { get; set; }
[Display(Name = "Category")]
public int? Category_id { get; set; }
[Display(Name = "Date")]
public DateTime PublishDate { get; set; }
[Display(Name = "Duration")]
[StringLength(150)]
public string Duration { get; set; }
}
这是我的代码：
using (StreamReader r = new StreamReader("/data.json"))
{
string json = r.ReadToEnd();
dynamic array = JsonConvert.DeserializeObject(json);
foreach (var item in array)
{
var ii = item;
}
}
我需要做的简单事情：
答案 0 :(得分：3)
我建议首先创建一些类以对JSON建模：
public class Course
{
public string Name { get; set; }
public string Category { get; set; }
public string Headline { get; set; }
public string CreatedBy { get; set; }
public string ExternalImage { get; set; }
public string Duration { get; set; }
public Description Description { get; set; }
}
public class Description
{
[JsonProperty("What You'll Learn")]
public List<string> WhatYoullLearn { get; set; }
public List<string> Requirements { get; set; }
[JsonProperty("Description")]
public string DescriptionHtml { get; set; }
}
然后，我建议反序列化到该类中，如下所示：
var json = File.ReadAllText("/data.json");
var courses = JsonConvert.DeserializeObject<Dictionary<string, Course>>(json);
foreach (var course in courses)
{
var courseName = course.Key;
var courseDetails = course.Value;
// Do something with the data, e.g save it to your database
}
