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
