角度传递列表值到JSON body - .Net核心和多对多关系

import { HttpClient } from '@angular/common/http';
// ...

constructor(private http: HttpClient) { }

sendListData() {
  const listData = [1, 2, 3, 4, 5];
  this.http.post('/api/listdata', listData).subscribe(response => {
    console.log(response);
  });
}

[ApiController]
[Route("api/[controller]")]
public class ListDataController : ControllerBase
{
    [HttpPost]
    public IActionResult PostListData([FromBody] List<int> listData)
    {
        // 处理接收到的列表值
        // ...

        return Ok("List data received");
    }
}
