C# 2 维 byte[][] 到 JSON.NET 到 C# byte[][] 或 Javascript 等效项失败

Question

我需要将字节[][] 从 C# WCF Web 服务发送到 JSON 客户端。

原始 WCF 结果如下（在倒数第二行查找AttributeData）：

{ “SA”：[ “BCtVgTmz5ZcCH34SZcsQrWQq3B7QVXSiPE57Vj7yZ / TwDNO + V3UkMr6wZKn8Fiu9 + / YNG0iESAKz4EcbimeLzQU =”， “BHez / TgkoKbRwTu / lqS18h1hagY9N9j6 / + cZhuHacWPPTgsoMOzNDInKDR7j6M + 1VAqRtCRVC2qFI4q6NFE0bRQ =”， “BL4DnZQMV / kLa5n + LviukZI2wSbsNmJb7R / Zs51Z0neRmC / JJkw5hmmU7Pkl9WoHjlMR + CERNehOiLaYvUqZfyU =”，” BPdEcJW8iVB74Cvxm720vVwxDnbVTm / jrkZ5vPb12JOXTltcTOt7wH9IeMQG9oArvgdjTevmvif09TVtaaT7uLs =”， “BFOZjjprurgN8pQszEkrUOvMybTFuj5Uitg563Rh08PoukbRcfGlyhLuYzev8m94h1fCv + Zg8i1PI0vWkgOEmlM =”]， “SB”：[ “BNTHLQWFFN / gFhQ + XaWfuONLZHBXHc1UMTqYSRtEPaqeSMe99wz3pKnHQdICzsvepY6btIRPLVFZCzK5MQ7v5Do =”， “BL6NBGy6vzJmPOJKu + WMQffLvnYw8gA + 7ZYiANTOP + / 5YpVELhsUva9OxS6CugsYvsaJIiAkV96ZbBVAyp9 / 2D0 =”， “BEWrUO7QXBPH68LEk7QTXAf064fBe8KTpy8MqsfcAAZ / nB10IHMnKBSdiU + nwNhnSnbc7zCsDSzA825iDQLv9yU =”， “BIJYfLEMeF + V6IG9jZBcEP4vp0FhEejX46uEup / lY890XNQEljFy4V1NUPSgDfTGxketJLyuaf + 0lTY1aeDEGTI =”， “BMwBbG / n3ylmxyo3wbxe6nODXyvJ0VpldnRZ6Wgpkn7CVcJMyXTMmhv5rxwwshq5Wbt6tFA4c3Bwy284KAAj5yI =”]， “SZ”：“+ BN39ATET17jdkI02lCEr5eQQpRS2n3f1Q2tE BTDNY / HuLCCo8Gu3hHHgPVX7 / kPN7 KmHBJlmqniKBxx5nOcXwE=",

客户

C# 消费者的代码如下所示：

 var converter = new ExpandoObjectConverter();
 dynamic obj = JsonConvert.DeserializeObject<ExpandoObject>(dataJsonAsListedAbove, converter);
 byte[][] a = (byte[][]) obj.AttributeData;
//  byte[][] a = obj.AttributeData;  // same error

最后一行出现的错误如下

RuntimeBinderException 未处理

未处理的类型异常 'Microsoft.CSharp.RuntimeBinder.RuntimeBinderException' 发生在 System.Core.dll

附加信息：无法隐式转换类型 'System.Collections.Generic.List' 到 'byte[][]'

问题

如何在 C# 中正确解码 JSON 中的二维 Array[][]？

供您参考，C# 服务器代码如下所示：

        byte[][] attributes = null;
        if (attributes == null)
        {
            // Evaluate the client proposed attributes and add demo data in certain circumstances
            List<byte[]> attList = new List<byte[]>();
            for (int i = 0; i < ikap.IssuerParameters.E.Length; i++)
            {
                attList.Add(encoding.GetBytes("Attribute" + i));
            }
            attributes = attList.ToArray();
        }

   //
  //  snip.. .firstMessage is a JSONString that we are appending to using this awkward method
  //
    dynamic obj = JsonConvert.DeserializeObject<ExpandoObject>(firstMessage, converter);
        obj.sid = "this is the new session id";
        obj.ti = "TokenData"; 
        obj.NumberOfTokens = 5;
        obj.AttributeData = attributes;

    // Returning the JSON as a stream so that .NET WCF doesn't escape the raw JSON we're sending.
    return returnAsStream(JsonConvert.SerializeObject(obj));

Answer 1

我在您的 json 中没有看到任何二维数组...

var obj  = JsonConvert.DeserializeObject<AClass>(DATA);
foreach (var data in obj.AttributeData)
{
    var buf = Convert.FromBase64String(data);
    Console.WriteLine(Encoding.UTF8.GetString(buf));
}
