visual studio 2022 初学流程

本文采用总-分的形式讲述流程
1.前端外部可以使用的接口 
     ExternalDataWebService.asmx?op=ReportWaterForWayder
   新建ExternalDataWebService.asmx 文件

<%@ WebService Language="C#" CodeBehind="~/App_Code/ExternalDataWebService.cs" Class="ExternalDataWebService" %>

新建ExternalDataWebService.cs文件，用于外部使用的接口方法

public void ReportWaterForWayder(string userid, string token, string begindate, string enddate)
{Context.Response.ContentType = "application/json";Context.Response.ContentEncoding = System.Text.Encoding.UTF8;Newtonsoft.Json.JsonSerializerSettings jsetting = new Newtonsoft.Json.JsonSerializerSettings();JsonConvert.DefaultSettings = new Func<JsonSerializerSettings>(() =>{//日期类型默认格式化处理jsetting.DateFormatHandling = Newtonsoft.Json.DateFormatHandling.MicrosoftDateFormat;jsetting.DateFormatString = "yyyy-MM-dd HH:mm:ss";//空值处理jsetting.NullValueHandling = NullValueHandling.Ignore;return jsetting;});Resultobject<List<WayderWaterReport>> result = new Resultobject<List<WayderWaterReport>>();try{result.Reponsecode = "0000";result.Reponsedesc = "";result.Resultmsg = new ExternalDataBizService().WayderWaterReportDingzhi(userid, token, begindate, enddate);Context.Response.Write(JsonConvert.SerializeObject(result, Formatting.Indented, jsetting));}catch (AuthException ae){result.Reponsecode = "2001";result.Reponsedesc = ae.Message;result.Resultmsg = null;Context.Response.Write(JsonConvert.SerializeObject(result, Formatting.Indented, jsetting));}catch (BizException le){result.Reponsecode = "1001";result.Reponsedesc = le.Message;result.Resultmsg = null;Context.Response.Write(JsonConvert.SerializeObject(result, Formatting.Indented, jsetting));}catch (Exception e){result.Reponsecode = "1002";result.Reponsedesc = e.Message;result.Resultmsg = null;Context.Response.Write(JsonConvert.SerializeObject(result, Formatting.Indented, jsetting));}finally{Context.Response.End();}
}

2.文中使用到的 new ExternalDataBizService().WayderWaterReportDingzhi(userid, token, begindate, enddate)方法以及WayderWaterReport的数据类型需要分别在ExternalDataBizService.cs文件和WayderWaterReport.cs文件中声明

public List<WayderWaterReport> WayderWaterReportDingzhi(string userid, string token, string begindate,string enddate)
