任何可以告诉我，我怎么能增加JSON legth限制？

Can any tell me how can I increase the JSON legth limit?

推荐答案

我有这种完全相同的问题。渐渐沮丧看到3.5和4.0的解决方案。原来你做同样的事情，你只需要几行添加到＆LT; ConfigSections＆GT; 标记你的web.config。它应该是当你把它粘贴到根目录下的第一个元素。

I had this same exact problem. Was getting frustrated seeing 3.5 and 4.0 solutions. Turns out you do the same thing, you just have to add a couple lines to the <ConfigSections> tag in your Web.config. It should be the first element under the root when you paste it in.

<configSections>
    <sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
        <sectionGroup name="scripting" type="System.Web.Configuration.ScriptingSectionGroup, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
            <sectionGroup name="webServices" type="System.Web.Configuration.ScriptingWebServicesSectionGroup, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
                <section name="jsonSerialization" type="System.Web.Configuration.ScriptingJsonSerializationSection, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false"/>
            </sectionGroup>
        </sectionGroup>
    </sectionGroup>
</configSections>

然后添加在实际＆LT; System.Web.Extensions程序＆GT; 部分：

<system.web.extensions>
  <scripting>
    <webServices>
      <jsonSerialization maxJsonLength="50000000"/>
    </webServices>
  </scripting>
</system.web.extensions>
