字符串的长度超过上maxJsonLength属性设置的值

问题描述

我的WebMethod通过加载通过jQuery的 AJAX post方法选项卡的内容数据与周围200-300记录。并获得以下错误控制台：

I am loading tab content data through jQuery's ajax post method via webmethod with around 200-300 records. And getting following error in the console:

错误：Sys.Net.WebServiceFailedException：
  Sys.Net.WebServiceFailedException：System.InvalidOperationException--
  使用JSON序列化和反串行化过程中的错误
  的JavaScriptSerializer。字符串的长度超过设定的值
  在maxJsonLength属性。

Chagning的长度

Chagning the length of the

maxJsonLength

于事无补。

Web.config文件设置为以下JSON atributes：

Web.config is set to following JSON atributes:

<configuration> 
   <system.web.extensions>
       <scripting>
           <webServices>
               <jsonSerialization maxJsonLength="2147483644" />
           </webServices>
       </scripting>
   </system.web.extensions>
</configuration>

谁能帮我解决这个问题？

Can anyone help me solve this?

推荐答案

JavaScriptSerialzer有根据名为MaxJsonLength公共财产

JavaScriptSerialzer has a public property named MaxJsonLength according to

http://msdn.microsoft.com/en-us/library/system.web.configuration.scriptingjsonserializationsection.maxjsonlength.aspx

现在，你在哪里你的反序列化JSON，使用

Now, where you are deserializing your json, use this

JavaScriptSerializer serializer = new JavaScriptSerializer();
serializer.MaxJsonLength = Int32.MaxValue; //Or any size you want to use, basically int maxValue is 2GB, you shouldn't need this big json string to deserialize, else you are doing it wrong.
myObject obj = serializer.Deserialize<yourObject>(yourJsonString);

这应该很好地工作，我最近通过MSDN想通了这一点，并解决了被窃听我很久的一个问题。

And this should work perfectly, I recently figured this out through msdn and solved a problem that was bugging me for long.
