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：

public
class DateTimeConverter : JavaScriptConverter{ public
override object Deserialize(IDictionary<string, object> dictionary, Type type, JavaScriptSerializer serializer) { return
new JavaScriptSerializer().ConvertToType(dictionary, type); } public
override IDictionary<string, object> Serialize(object
obj, JavaScriptSerializer serializer) { if
(!(obj is
DateTime)) return
null; return
new CustomString(((DateTime)obj).ToString("yyyy-MM-dd")); } public
override IEnumerable<Type> SupportedTypes { get
{ return
new[] { typeof(DateTime) }; } } private
class CustomString : Uri, IDictionary<string, object> { public
CustomString(string
str) : base(str, UriKind.Relative) { } void
IDictionary<string, object>.Add(string
key, object
value) { throw
new NotImplementedException(); } bool
IDictionary<string, object>.ContainsKey(string
key) { throw
new NotImplementedException(); } ICollection<string> IDictionary<string, object>.Keys { get
{ throw
new NotImplementedException(); } } bool
IDictionary<string, object>.Remove(string
key) { throw
new NotImplementedException(); } bool
IDictionary<string, object>.TryGetValue(string
key, out
object value) { throw
new NotImplementedException(); } ICollection<object> IDictionary<string, object>.Values { get
{ throw
new NotImplementedException(); } } object
IDictionary<string, object>.this[string
key] { get { throw
new NotImplementedException(); } set { throw
new NotImplementedException(); } } void
ICollection<KeyValuePair<string, object>>.Add(KeyValuePair<string, object> item) { throw
new NotImplementedException(); } void
ICollection<KeyValuePair<string, object>>.Clear() { throw
new NotImplementedException(); } bool
ICollection<KeyValuePair<string, object>>.Contains(KeyValuePair<string, object> item) { throw
new NotImplementedException(); } void
ICollection<KeyValuePair<string, object>>.CopyTo(KeyValuePair<string, object>[] array, int
arrayIndex) { throw
new NotImplementedException(); } int
ICollection<KeyValuePair<string, object>>.Count { get
{ throw
new NotImplementedException(); } } bool
ICollection<KeyValuePair<string, object>>.IsReadOnly { get
{ throw
new NotImplementedException(); } } bool
ICollection<KeyValuePair<string, object>>.Remove(KeyValuePair<string, object> item) { throw
new NotImplementedException(); } IEnumerator<KeyValuePair<string, object>> IEnumerable<KeyValuePair<string, object>>.GetEnumerator() { throw
new NotImplementedException(); } IEnumerator IEnumerable.GetEnumerator() { throw
new NotImplementedException(); } }} |
然后注册一下就行了：

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
