How to parse json file
问题
我在解析中遇到了问题
我的 JSON 文件：
[{
"username": "abc",
"number": "1",
"Coordinates": "3479087.7179635554,4723293.992024612,3587934.046241646,4936094.678770542"
},
{
"username": "ab",
"number": "2",
"Coordinates": "3638076.736796722,4693942.173163104,3669874.540563355,4955662.558011548"
}]
模型：
namespace WebUygAPI.Models
{
public class DrawInfo
{
public string username { get; set; }
public string number { get; set; }
public string coordinates { get; set; }
}
}
我在控制器中遇到的问题是：
[HttpGet]
[Route("GetDraws")]
public async Task<IActionResult> get()
{
string filePath = @"C:\Users\Casper\source\repos\WebUygAPI\WebUygAPI\LineData.json";
using (StreamReader file = new StreamReader(filePath))
{
string o1 = file.ReadToEnd();
}
return Ok();
}
当我进行调试时，我可以看到 o1 中的 JSON 文件，但我无法解析它。
我尝试进行解析，但出现了错误，例如
newtonsoft.json.jsonreaderexception: 在解析值时遇到意外字符

I have a problem with parsing
my json file:
[{
"username": "abc",
"number": "1",
"Coordinates": "3479087.7179635554,4723293.992024612,3587934.046241646,4936094.678770542"
},
{
"username": "ab",
"number": "2",
"Coordinates": "3638076.736796722,4693942.173163104,3669874.540563355,4955662.558011548"
}]
modal:
namespace WebUygAPI.Models
{
public class DrawInfo
{
public string username { get; set; }
public string number { get; set; }
public string coordinates { get; set; }
}
}
The problem I'm having in the controller is:
[HttpGet]
[Route("GetDraws")]
public async Task<IActionResult> get()
{
string filePath = @"C:\Users\Casper\source\repos\WebUygAPI\WebUygAPI\LineData.json";
using (StreamReader file = new StreamReader(filePath))
{
string o1 = file.ReadToEnd();
}
return Ok();
}
When I'm debugging I can see json file in o1 but I couldn't parse it.
I tried to parse but I had errors such as
> newtonsoft.json.jsonreaderexception: unexpected character encountered while parsing value
答案1
得分: -1
我建议使用这段代码：
使用 Newtonsoft.Json;
var json = File.ReadAllText(filePath);
List<DrawInfo> info = JsonConvert.DeserializeObject<List<DrawInfo>>(json);
英文:
I recommend this code
using Newtonsoft.Json;
var json = File.ReadAllText(filePath);
List<DrawInfo> info = JsonConvert.DeserializeObject<List<DrawInfo>>(json);
