Processing of DateTime data when JavaScriptSerializer is serialized into Json

JavaScriptSerializer serializes DateTime data into values similar to \/Date (626543800000) \/During serialization. Many methods are not satisfactory, finally, I found a perfect solution in a blog. Address: Workshop:

 

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();        }    }}

　　

Then, just register it:

 

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

　　

In this way, the objects serialized with serializer contain values of the DateTime type will be converted into strings in the yyyy-MM-dd format.
