JavaScriptSerializer序列化成Json时DateTime类型数据的处理

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：

1 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
