asp.net mvc异常信息 Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.
在ASP.NET MVC中，当你遇到使用JavaScriptSerializer进行JSON序列化或反序列化时出现的错误，提示“字符串长度超过了在maxJsonLength属性上设置的值”，这通常意味着你正在尝试处理的数据量超过了默认的最大限制。JavaScriptSerializer的maxJsonLength属性默认设置为一个相对较小的值（通常是102400字节，即100KB），这可能会导致在处理大数据集时出错。
