在.Net Core2.0中从HttpContext读取FormData

using Microsoft.AspNetCore.Http;

public class MyController : Controller
{
    private readonly IHttpContextAccessor _httpContextAccessor;

    public MyController(IHttpContextAccessor httpContextAccessor)
    {
        _httpContextAccessor = httpContextAccessor;
    }

    public IActionResult MyAction()
    {
        HttpContext context = _httpContextAccessor.HttpContext;
        IFormCollection formData = context.Request.Form;

        // 通过键名获取FormData值
        string value = formData["key"];

        // 遍历所有的FormData键值对
        foreach (var item in formData)
        {
            string key = item.Key;
            string value = item.Value;
            // 处理键值对
        }

        // 其他操作...

        return View();
    }
}
