JavaScriptSerializer在序列化时会将DateTime的数据序列化成类似\/Date(626543800000)\/这样的值，找了很多方法都不如意，最后在一个博客找到了完美的解决方法，地址：http://blog.calyptus.eu/seb/2011/12/custom-datetime-json-serialization/，通过自定义类型转换器的方式转换成想要的格式，转换器代码如下：

然后注册一下就行了：

2
|
public
JavaScriptSerializer serializer = new
JavaScriptSerializer();
serializer.RegisterConverters(new
JavaScriptConverter[] { new
DateTimeConverter() });
|
这样使用serializer序列化的对象中包含DateTime类型的值就会被转化成yyyy-MM-dd格式的字符串
