.net 高级写法总结

1、处理HTTP非正常的请求参数:

　　[1] 获取相应的流转为string

       [2] request 的只读属性设置为可编辑，类似form

       [3] 转换为json对象

       [4] 重设只读属性

 

   //判断请求类似如果不是form类型而是application/json;charset=UTF-8
            if(HttpContext.Current.Request.ContentType.IndexOf("application/json")>-1)
            {
                byte[] byts = new byte[HttpContext.Current.Request.InputStream.Length];
                HttpContext.Current.Request.InputStream.Read(byts, 0, byts.Length);
                string jsonText = System.Text.Encoding.Default.GetString(byts);
                jsonText = HttpContext.Current.Server.UrlDecode(jsonText);
                JObject jo = (JObject)JsonConvert.DeserializeObject(jsonText);

                //构造只读集合
                PropertyInfo formreadonly = typeof(System.Collections.Specialized.NameValueCollection).GetProperty("IsReadOnly", BindingFlags.Instance | BindingFlags.NonPublic);
                //设置form 为可编辑
                formreadonly.SetValue(HttpContext.Current.Request.Form, false, null);

                foreach(var p in jo.Properties())
                {

                    HttpContext.Current.Request.Form.Add(p.Name,p.Type.Equals(JTokenType.String)?p.Value.ToString():null);
                }

                formreadonly.SetValue(HttpContext.Current.Request.Form, true, null);
               
            }
