英文:
Read json file with unique parent elements in .net core
问题
以下是翻译好的内容：
如何在.NET中读取JSON文件。
问题是父元素是唯一的，所以很难创建一个表示这个结构的类。
当我使用下面的代码时，它返回一个空数组。当我尝试在在线工具中将其转换为C#模型时，它为每个元素创建一个新类。
理想的输出应该是一个包含所有信息的平面数组。
这是我有的类
public class NmpLicense
{
public string licenses { get; set; }
public string repository { get; set; }
public string publisher { get; set; }
public string email { get; set; }
public string path { get; set; }
public string licenseFile { get; set; }
}
这是我读取文件的方式
public static async Task<T> ReadAsync<T>(string filePath)
{
try
{
using FileStream stream = File.OpenRead(filePath);
return await JsonSerializer.DeserializeAsync<T>(stream);
}
catch (JsonException ex)
{
}
return default(T);
}
英文:
How do I read a json file in .net.
The issue is parent element is unique so it is hard to create a class to represent this structure.
When I use the code below it returns an empty array. When I try to convert this in an online tool to C# model, it creates a new class for each element.
The ideal output should be a flat array with all information.

}
This is the class I have
public class NmpLicense
{
public string licenses { get; set; }
public string repository { get; set; }
public string publisher { get; set; }
public string email { get; set; }
public string path { get; set; }
public string licenseFile { get; set; }
}
And this is how I read the file
public static async Task<T> ReadAsync<T>(string filePath)
{
try
{
using FileStream stream = File.OpenRead(filePath);
return await JsonSerializer.DeserializeAsync<T>(stream);
}
catch (JsonException ex)
{
}
return default(T);
}

以下是代码的翻译部分：
// 理想的输出应该是一个包含所有信息的平面数组。
尝试：
public static async Task<T> ReadAsync<T>(string fullPath)
{
try
{
var jsonData = System.IO.File.ReadAllText(fullPath);
var parsedJson = JObject.Parse(jsonData);
var arrays = parsedJson.Root.Values()
.Select(x => new NmpLicense
{
licenses = (string)x["licenses"],
repository = (string)x["repository"],
publisher = (string)x["publisher"],
email = (string)x["email"],
path = (string)x["path"],
licenseFile = (string)x["licenseFile"],
}).ToArray();
}
catch (JsonException ex)
{
}
return default(T);
}
