Ajax请求成功但是一直进入error 之 序列化类型为“System.Reflection.RuntimeModule”的对象时检测到循环引用。解决方案

$.ajax({
     url: $("#dataMain").attr("data-url"),
     type: "GET",
     dataType: "json",
     timeout: 3000,
     data: data,
     success: function (res) {
          console.log(res);
      },
      error: function (res) {
           console.log(res);
      }
});

 [HttpGet]
 public JsonResult Test1() 
 {
     var sql = string.Format(@"SELECT * FROM RELEASE ");

     DataTable dataTable = GlobalContext.Resolve<ISource_Web_SQLHelper>().GetDataSet(sql, "你的数据库链接串").Tables[0]

     return Json(dataTable, JsonRequestBehavior.AllowGet);
}
        

error: function (res) {
    console.log(res);
}

JsonSerializerSettings setting = new JsonSerializerSettings()
{
    ReferenceLoopHandling = ReferenceLoopHandling.Ignore
};

var data = JsonConvert.SerializeObject(dataTable, setting);

return Json(data, JsonRequestBehavior.AllowGet);

var data=dataTable.AsEnumerable().ToList();

return Json(data, JsonRequestBehavior.AllowGet);
