Question

我正在尝试将我的winform c＃deskltop移植到uwp。

在我的代码的这一部分中，我调用web api来返回序列化列表。

它也被压缩了。

这是现有的代码：

Uri uri = new Uri(URL);
httpClient.DefaultRequestHeaders.Accept.Clear();
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("text/plain"));
HttpResponseMessage response = await httpClient.GetAsync(uri + route + "?" + COMPANY_REF + "=" + ApplicationObject.CompanyRef);
response.EnsureSuccessStatusCode();
var result = response.Content.ReadAsByteArrayAsync().Result;
string result2 = System.Text.Encoding.ASCII.GetString(result);
byte[] actualBytes = Convert.FromBase64String(result2.Replace("\"",""));                  
var myobj= Compression.DeSerialize(actualBytes);

我的压缩代码：

public static byte[] Decompress(byte[] input)
{
    byte[] decompressedData;

    using (var outputStream = new MemoryStream())
    {
        using (var inputStream = new MemoryStream(input))
        {
            using (var zip = new GZipStream(inputStream, CompressionMode.Decompress))
            {
                zip.CopyTo(outputStream);
            }
        }
        decompressedData = outputStream.ToArray();
    }
    return decompressedData;
}
public static Object DeSerialize(this byte[] arrBytes)
{
    using (var memoryStream = new MemoryStream())
    {
        var binaryFormatter = new BinaryFormatter();
        var decompressed = Decompress(arrBytes);
        memoryStream.Write(decompressed, 0, decompressed.Length);
        memoryStream.Seek(0, SeekOrigin.Begin);
        return binaryFormatter.Deserialize(memoryStream);
    }
}

和我的模特：

[Serializable, XmlRoot("Groups"), XmlType("Groups")]
public class Groups
{
    public Groups()
    {
        group = new List<Group>();
    }

    [XmlElement("Group")]
    public List<Group> group { get; set; }
}

，XmlRoot（“Group”），XmlType（“Group”）] 公共班组 { [XmlElement的（ “GroupRef”）] 公共Guid GroupRef; [XmlElement的（ “名称”）] 公共字符串名称; [XmlElement的（ “描述”）] public string描述; }

现在把它移植到UWP我有这个：

Uri uri = new Uri(Shared.URL);
httpClient.DefaultRequestHeaders.Accept.Clear();
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/text"));
HttpResponseMessage response = await httpClient.GetAsync(uri + route + "?" + GeneralTags.COMPANY_REF + "=" + ApplicationObject.CompanyRef);
response.EnsureSuccessStatusCode();
var result = response.Content.ReadAsByteArrayAsync().Result;
string result2 = System.Text.Encoding.ASCII.GetString(result);
byte[] actualBytes = Convert.FromBase64String(result2.Replace("\"", ""));                  
var myobj = Compression.DeSerialize<InformedWorker.Models.Group>(actualBytes);

我的压缩代码：

public static byte[] Compress(byte[] input)
{
    byte[] compressesData;

    using (var outputStream = new MemoryStream())
    {
        using (var zip = new GZipStream(outputStream, CompressionMode.Compress))
        {
            zip.Write(input, 0, input.Length);
        }

        compressesData = outputStream.ToArray();
    }
    return compressesData;
}
public static T DeSerialize<T>(byte[] arrBytes)
{
    var decompressed = Decompress(arrBytes);
    using (MemoryStream memoryStream = new MemoryStream(decompressed))
    {
        using (XmlDictionaryReader reader = XmlDictionaryReader.CreateBinaryReader(memoryStream, XmlDictionaryReaderQuotas.Max))
        {
            DataContractSerializer dcs = new DataContractSerializer(typeof(T));
            return (T)dcs.ReadObject(reader);
        }
    }
}

和我的模特：

public class Groups
{
    public Groups()
    {
        group = new List<Group>();
    }

    [XmlElement("Group")]
    public List<Group> group { get; set; }
}

public class Group
{
    [XmlElement("GroupRef")]
    public Guid GroupRef;
    [XmlElement("Name")]
    public string Name;
    [XmlElement("Description")]
    public string Description;
}

请注意：我不被允许使用'[Serializable~'所以我必须删除。

另外，我找不到BinaryFormatter，所以不得不使用'DataContractSerializer'。

这行错误：

return (T)dcs.ReadObject(reader);

，错误是：

There was an error deserializing the object of type  The input source is not correctly formatted.

我正在使用这种方法，以便我可以将数据从服务器压缩到客户端。

有关如何使其发挥作用的任何想法吗？

感谢

附加：

这是我正在从服务器压缩/发送的XML：

<Groups>
  <Group>
    <GroupId>1</GroupId>
    <GroupRef>00000000-0000-0000-0000-000000000000</GroupRef>
    <Name>Todays Work</Name>
    <Description>System</Description>
    <CompanyRef>00000000-0000-0000-0000-000000000000</CompanyRef>    
    <Active>1</Active>
  </Group>
  <Group>
    <GroupId>2</GroupId>
    <GroupRef>00000000-0000-0000-0000-000000000000</GroupRef> 
    <Name>All</Name>
    <Description>System</Description>
    <CompanyRef>00000000-0000-0000-0000-000000000000</CompanyRef> 
    <Active>1</Active>
  </Group>
</Groups>

Answer 1

等待ReadAsByteArraysAsync。在

中读取数据之前，代码不会继续到下一行

var result = await response.Content.ReadAsByteArrayAsync();

反序列化类型＆lt;＆gt;的对象时出错输入源格式不正确
