C#后端接收form-data,创建实体类教程

public class Para_list  //实体类
    {
        public long ParemeterID { get; set; }
        public string Name { get; set; }
        public string Scope { get; set; }
        public string Require { get; set; }
        public string Basis { get; set; }
        public string ParemeterResult { get; set; }
    }

List<Para_list> paramentitys = JsonHelper.DeserializeJsonToObject<List<Para_list>>(Parameters);
                            if (!string.IsNullOrWhiteSpace(Parameters))
                            {
                                for (int i = 0; i < paramentitys.Count; i++)
                                {
                                    long checkID = paramentitys[i].ParemeterID;
                                    var ResultQuery = dbContext.checkresult.Where(o => o.ID == checkID).FirstOrDefault();
                                    ResultQuery.Result = paramentitys[i].ParemeterResult;
                                    dbContext.SaveChanges();
                                }
                            }

var form = new FormData(); 
form.append("myName", "Robert"); 

var xhrForm = new XMLHttpRequest(); 
xhrForm.open("POST", "getfile.php"); 
xhrForm.send(form); 

string addTime = Request["myName"];
HttpPostedFile file = Request.Files["Filedata"];
