javaScriptSerializer序列化成Json時DateTime類型數據的處理

JavascriptSerializer在序列化時會將DateTime的數據序列化成類似//Date(626543800000)//這樣的值，找了很多方法都不如意，最后在一個博客找到了完美的解決方法，地址：http://blog.calyptus.eu/seb/2011/12/custom-datetime-json-serialization/，通過自定義類型轉換器的方式轉換成想要的格式，轉換器代碼如下：

public class DateTimeConverter : JavaScriptConverter{PRivate string format = "yyyy-MM-dd";public DateTimeConverter(string format){this.format = format;}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(format));}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();}}}

然后注冊一下就行了：

public JavaScriptSerializer serializer = new JavaScriptSerializer();serializer.RegisterConverters(new JavaScriptConverter[] { new DateTimeConverter("yyyyMMdd") });

這樣就可以通過構造函數自定義serializer序列化的對象中包含DateTime類型的值的格式
