Question

我设计了jqgrid来显示数据，但在执行时我收到了错误;

“Message”：“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maxJsonLength属性上设置的值。”，“StackTrace”：“

当我用最少的数据执行网格时......

我甚至尝试通过以下方式更改web.conf：

<scripting>
<webServices>
  <jsonSerialization maxJsonLength="50000000"/>
</webServices>

但错误仍然相同.Below是我的web.conf文件..

<compilation debug="true" targetFramework="4.0">
        <assemblies>
            <add assembly="MySql.Data, Version=5.0.9.0, Culture=neutral, PublicKeyToken=C5687FC88969C44D"/></assemblies></compilation>

我不知道这是否是您问题的解决方案。尝试在代码后面设置maxJsonLength（动态）：

public static string GetJSONString <T> (List<T> data)
{
    JavaScriptSerializer serializer = new JavaScriptSerializer() { MaxJsonLength = Int32.MaxValue, RecursionLimit = 100 };
    return serializer.Serialize(data);
}

创建对象时初始化MaxJsonLength属性。如果此解决方案不起作用，我认为您应该分隔您的JSON字符串lenghth。希望这有帮助。
