下面说明使用Core坑

一、基于Core的获取文件上传

1、（List<IFormFile> files）

前端代码:

后台代码:

2、（[FromForm(Name = "file")] List<IFormFile> files）

        [HttpPost]

        public async Task<IActionResult> Uploadurl([FromForm(Name = "file")] List<IFormFile> files) //上传图片

        {

            if (files.Count > )

            {

                string path = Path.Combine(Environment.CurrentDirectory, "Upload", DateTime.Now.ToString("yyyy-MM-dd"));

                if (!System.IO.Directory.Exists(path))//判断上传路径是否存在

                {

                    System.IO.Directory.CreateDirectory(path);

                }

                string filePath = string.Empty;

                string fileName = string.Empty;

                foreach (var formFile in files)

                {

                    if (formFile.Length > )

                    {

                        string fileFormat = System.IO.Path.GetExtension(formFile.FileName);//获取文件后缀格式

                        fileName = Guid.NewGuid().ToString("n") + fileFormat;

                        filePath = Path.Combine(path,fileName);//中间处理为唯一格式文件

                        using (var stream = new FileStream(filePath, FileMode.Create))

                        {

                            try

                            {

                                //保存文件

                                await formFile.CopyToAsync(stream);

                            }

                            catch (Exception ex)

                            {

                                return Json(new { Status = , Message = "保存失败" });

                            }

                        }

                    }

                }

                return Json(new { Status = , Message = "保存成功" });

            }

            else

            {

                return Json(new { Status = , Message = "上传文件为空!" });

            }

        }

二、基于MVC的获取文件上传

        [HttpPost]

        public ActionResult Uploadurl(HttpPostedFileBase file) //上传图片

        {

            Basics basics = new Basics();

            if (basics.SaveFiles(file))

            {

                return Json(new { Status=, Message = "保存成功"}, "text/html", JsonRequestBehavior.AllowGet);

            }

            else {

                return Json(new { Status = , Message = "保存失败" }, "text/html", JsonRequestBehavior.AllowGet);

            }

        }

封装方法

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Web; //

namespace Common

{

    public class Basics

    {

        public bool SaveFiles(HttpPostedFileBase file)

        {

            try

            {

                var Filename = file.FileName;

                string SavePath = "../Uploads/";

                string _Filename = DateTime.Now.ToString("yyyyMMddhhmmss") + Filename;

                //保存

                //Server.MapPath()的全名是System.Web.HttpContext.Current.Server.MapPath()

                file.SaveAs(System.Web.HttpContext.Current.Server.MapPath(SavePath + _Filename));

            }catch

            {

                return false;

            }

            finally {

            }

            return true;

        }

    }

}
