JSON序列化的base64二进制使用DataContractJsonSerializer .NET [英] deserialize json base64 binary in .net using DataContractJsonSerializer

问题描述

我有使用WCF datacontract反序列化的base64 JSON回.NET对象的问题....

我有这样的反序列化：

 公共静态牛逼FromJSON＆LT; T＆GT;（此字符串JSON）
{
    使用（MemoryStream的毫秒=新的MemoryStream（ASCIIEncoding.Default.GetBytes（JSON）））
    {
        DataContractJsonSerializer SER =新DataContractJsonSerializer（typeof运算（T））;        回报（T）ser.ReadObject（MS）;
    }
}
 

和...我有这个在我的模型类...

  [数据成员]
[列（自动同步= AutoSync.Always，的DbType =rowversion非空，CanBeNull =假，IsDbGenerated = TRUE，IsVersion = TRUE，UpdateCheck的= UpdateCheck.Never）
公共字节[] {时间戳获得;组; }
 

和... ...我传递回JSON像这样...

<$p$p><$c$c>[{\"id\":\"1\",\"type\":\"H\",\"date_issued\":\"\\/Date(1286856000000)\\/\",\"date_ceu\":\"\\/Date(1603166400000)\\/\",\"current\":true,\"timestamp\":\"AAAAAAAAD7M=\"}]

和出于某种原因，它只是拒绝简单地说是的base64回的byte [] ...必须有一些其他的方式来得到它的工作...

另外，仅供参考我使用ASP.NET MVC和Html.Hidden（...）的串行二进制进的base64开始与....

谢谢！

解决方案

我用JSON.NET库，而不是解决问​​题......马上工作。

Hey, I am having a problem deserializing base64 json back into the .net object using wcf datacontract....

I have this to deserialize:

public static T FromJSON<T>( this string json )
{
    using ( MemoryStream ms = new MemoryStream(ASCIIEncoding.Default.GetBytes(json)) )
    {
        DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));

        return (T)ser.ReadObject(ms);
    }
}

and...I have this in my model class...

[DataMember]
[Column(AutoSync = AutoSync.Always, DbType = "rowversion not null", CanBeNull = false, IsDbGenerated = true, IsVersion = true, UpdateCheck = UpdateCheck.Never)]
public byte[] timestamp { get; set; }

and...I'm passing the json back like so...

[{"id":"1","type":"H","date_issued":"\/Date(1286856000000)\/","date_ceu":"\/Date(1603166400000)\/","current":true,"timestamp":"AAAAAAAAD7M="}]

and for some reason it just refuses to simply put that base64 back into the byte[]...there must be some other way to get it to work...

also, fyi I'm using ASP.NET MVC and Html.Hidden(...) which serializes the binary into base64 to begin with....

thanks!

解决方案

I solved the issue by using JSON.NET library instead...worked immediately.

List<..> result = JsonConvert.DeserializeObject<List<...>>( list );
