是我的代码。 

Hi i am new to C# and visual studio i am trying to read a .csv file into my Web Application MVC project and can not find the correct tutorials i have tried multiple different ways and keep getting the same errors on the same pieces of code  listed below is the code I have. 

[System.Web.Mvc.HttpPost]
        public ActionResult Index(HttpPostedFileBase postedFile)
        {
            List<TeamModel> team = new List<TeamModel>();
            string filePath = string.Empty;
            if (postedFile != null)
            {
                string path = Server.MapPath("~/Uploads/");
                if (!Directory.Exists(path))
                {
                    Directory.CreateDirectory(path);
                }

                filePath = path + Path.GetFileName(postedFile.FileName);
                string extension = Path.GetExtension(postedFile.FileName);
                postedFile.SaveAs(filePath);

                //Read the contents of CSV file.
                string csvData = System.IO.File.ReadAllText(filePath);

                //Execute a loop over the rows.
                foreach (string row in csvData.Split('\n'))
                {
                    if (!string.IsNullOrEmpty(row))
                    {
                        team.Add(new TeamModel
                        {
                            ID = Convert.ToInt32(row.Split(',')[0]),
                            player_name = row.Split(',')[1],
                            quality = row.Split(',')[2],
                            overall = row.Split(',')[2],
                            club = row.Split(',')[2],
                            league = row.Split(',')[2],
                            nationality = row.Split(',')[2],
                            position = row.Split(',')[2],
                            age = row.Split(',')[2],
                        });
                    }
                }
            }

            return View(team);
        }

1. 错误 CS0246类型或命名空间名称'找不到HttpPostedFileBase'（您是否缺少using指令或汇编引用？）
2. 错误 CS0103
   当前上下文中不存在"服务器"名称
   

1. Error CS0246 The type or namespace name 'HttpPostedFileBase' could not be found (are you missing a using directive or an assembly reference?)
2. Error CS0103 The name 'Server' does not exist in the current context

这些是我得到的错误，有人可以帮助我，我发现的所有教程都是针对VS 2010,2015 2017年没有一个不确定是否有所作为。我只是想从项目文件夹中读取一个csv文件并将其放入List<>
i不需要上传文件 

these are the errors I am getting can someone please help me all the tutorials I found was for VS 2010, 2015 none for 2017 not sure if that makes a difference. I am just trying to read a csv file from inside the project folder and put it in a List<> i do not need to upload the file
