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：

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114

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
