如何将数组从angular 8发送到web api核心？

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

@Injectable({
  providedIn: 'root'
})
export class ApiService {
  constructor(private http: HttpClient) { }

  sendData(data: any[]) {
    const url = 'http://api.example.com/endpoint'; // 替换为你的Web API地址
    return this.http.post(url, data);
  }
}

import { Component } from '@angular/core';
import { ApiService } from './api.service';

@Component({
  selector: 'app-root',
  template: `
    <button (click)="sendArray()">发送数组</button>
  `
})
export class AppComponent {
  arrayToSend: any[] = [1, 2, 3, 4]; // 替换为你的数组数据

  constructor(private apiService: ApiService) { }

  sendArray() {
    this.apiService.sendData(this.arrayToSend).subscribe(
      response => {
        // 处理成功响应
      },
      error => {
        // 处理错误
      }
    );
  }
}

using Microsoft.AspNetCore.Mvc;

namespace YourWebApiProject.Controllers
{
    [ApiController]
    [Route("[controller]")]
    public class DataController : ControllerBase
    {
        [HttpPost]
        public IActionResult ReceiveData([FromBody] int[] data)
        {
            // 处理接收到的数组数据
            return Ok();
        }
    }
}
