当调用webfrom中的ashx相应的接口时，返回的格式和webapi不一样（很坑，从net core 3.1  webapi现在又来搞webform了）

public void GetPictureMaterialUrl(HttpContext context)
    {
        var query = "select url from PictureMaterial";
        var result = DB.DataSet(ConnectionString, query);
        List<string> list = new List<string>();
        if (result.Tables.Count > 0 && result.Tables[0].Rows.Count > 0)
        {
            for (int i = 0; i < result.Tables[0].Rows.Count; i++)
            {
                var item = result.Tables[0].Rows[i][0].ToString();
                if (!string.IsNullOrEmpty(item))
                {
                    list.Add(item);
                }
            }
        }
        context.Response.ContentType = "application/json";
        context.Response.ContentEncoding = Encoding.UTF8;
        context.Response.Write(Newtonsoft.Json.JsonConvert.SerializeObject(list));
        context.Response.End();
    }
