使用 JSON JavaScriptSerializer 进行序列化或反序列化时出错。字符串的长度超过了为 maxJsonLength 属性设置的值。
一、Mvc中
//post请求 [HttpPost] public JsonResult Info (string name) { var data ="测试数据,你可以搞多点"; return new JsonResult() { Data = data, MaxJsonLength = int.MaxValue, ContentType = "application/json" }; } //get请求 [HttpGet] public JsonResult Info (string name) { var data ="测试数据,你可以搞多点"; return new JsonResult() { Data = data, MaxJsonLength = int.MaxValue, ContentType = "application/json" , JsonRequestBehavior = JsonRequestBehavior.AllowGet }; } 加上: JsonRequestBehavior = JsonRequestBehavior.AllowGet
二、借鉴来源:

不同之处:一个是ActionResult ,一个是JsonResult。
三、失败经历:
此方案对JsonResult无效;

1.解决办法是在web.config增加如下节点到<configuration>下
<system.web.extensions>
<scripting>
<webServices>
<jsonSerialization maxJsonLength="1024000000" />
</webServices>
</scripting>
</system.web.extensions>
2.
JavaScriptSerializer jsSerializer = new JavaScriptSerializer(); jsSerializer.MaxJsonLength = Int32.MaxValue;
树立目标,保持活力,gogogo!
