我有DTO课程

[DataContract]
    public class RequestMetaDataXml
    {
        [DataMember(Name = "Title")]
        public string Title { get; set; }

        [DataMember(Name = "ExpiryDate")]
        public string ExpiryDate { get; set; }

        [DataMember(Name = "AllowDownload")]
        public string AllowDownload { get; set; }

        [DataMember(Name = "IsShare")]
        public string IsShare { get; set; }

        [DataMember(Name = "IncludeMetadata")]
        public string IncludeMetadata { get; set; }

        [DataMember(Name = "IsReel")]
        public string IsReel { get; set; }

        [DataMember(Name = "IsSecuredPublish")]
        public string IsSecuredPublish { get; set; }

        [DataMember(Name = "Notifications")]
        public List<NotificationId> Notifications { get; set; }

        [DataMember(Name = "CoverArt")]
        public List<CoverArt> Coverart { get; set; }

        [DataMember(Name = "ProfileInfo")]
        public List<ProfileInfo> Profileinfo { get; set; }
    }


    [DataContract]
    public class NotificationId
    {
        [DataMember(Name = "Id")]
        public string Id { get; set; }

        [DataMember(Name = "Type")]
        public string Type { get; set; }
    }

    [DataContract]
    public class CoverArt
    {
        [DataMember(Name = "UploadedFileName")]
        public string UploadedFileName { get; set; }
    }

    [DataContract]
    public class ProfileInfo
    {
        [DataMember(Name = "Watermark")]
        public List<WaterMark> WaterMark { get; set; }
    }

    [DataContract]
    public class WaterMark
    {
        [DataMember(Name = "VideoWatermark")]
        public List<VideoWatermark> VideoWatermark { get; set; }
    }

    [DataContract]
    public class VideoWatermark
    {
        [DataMember(Name = "WaterMarkInfo")]
        public List<WaterMarkInfo> WaterMarkInfo { get; set; }
    }

    [DataContract]
    public class WaterMarkInfo
    {
        [DataMember(Name = "Type")]
        public string Type { get; set; }

        [DataMember(Name = "FreeText")]
        public string FreeText { get; set; }

        [DataMember(Name = "Position")]
        public string Position { get; set; }

        [DataMember(Name = "Size")]
        public string Size { get; set; }

        [DataMember(Name = "LogoId")]
        public string LogoId { get; set; }
    }

我有像Json String一样的

"{\"RequestMetaDataXml\":{
                            \"Title\":\"TestCheck27\",
                            \"AllowDownload\":true,
                            \"IsShare\":true,
                            \"IncludeMetadata\":true,
                            \"IsReel\":\"false\",
                            \"IsSecuredPublish\":\"true\",

                                                \"Id\":\"checktest1@ssss.com\",
                                                \"Type\":\"ExtUser\"},
                            \"CoverArt\":{

                                            \"WaterMark\":{
                                                            \"VideoWatermark\":{
                                                                    \"WaterMarkInfo\":{
                                                                                        \"Type\":\"None\",
                                                                                        \"FreeText\":\"\",
                                                                                        \"Position\":
                                                                                        \"MiddleCenter\",
                                                                                        \"Size\":\"Medium\",
                                                                                        \"LogoId\":\"7\"
                                                                                       }
                                                                                }
                                                            }
                                            }
                        }
}"

我收到了Json序列化的字符串，我怎么能分配到Above DTO？我试图反序列化json字符串，因为它不适合我。

RequestMetaDataXml MetaDataDTO =new RequestMetaDataXml();
                MetaDataDTO = JsonConvert.DeserializeObject<RequestMetaDataXml>(arguments["MetaDataDTO"]);

我通过以下方法生成Json

var MetaDataDTO = {
        Title:replacedtitle ,
        Expirydate: expirydate,
        AllowDownload: checkallowdownload,
        IsShare: chkAllowShare,
        IncludeMetadata: chkincludeMetadata,
        IsReel: "false",
        IsSecuredPublish: IsSecuredPublish,
        Notifications: NotificationId,
        CoverArt: { UploadedFileName: UploadedFileName },
        ProfileInfo: {
            WaterMark: {
                VideoWatermark: {
                    WaterMarkInfo: {
                        Type : WaterMarkInfoType,
                        FreeText : WaterMarkText,
                        Position: WaterMarkPosition,
                        Size: WaterMarkSize,
                        LogoId : LogoId
                    }
                }
            }
        }
    }

如何在c＃代码中反序列化Json的值以及如何将这些值分配到我的自定义DTO中？

我必须像这样构建像Xml数据

<Title></Title>
    <ExpiryDate> </ExpiryDate>
    <AllowDownload> </AllowDownload>
    <IsShare> </IsShare>
    <IncludeMetadata> </IncludeMetadata>
    <IsReel> </IsReel>
    <IsSecuredPublish> </IsSecuredPublish>
    <Notifications>
        <NotificationId id= type= ></NotificationId>
    </Notifications>
    <CoverArt>
        <UploadedFileName> </UploadedFileName>
    </CoverArt>
    <ProfileInfo>
        <Watermark>
            <VideoWatermark>
                <WaterMarkInfo>
                    <Type> </Type>
                    <FreeText></FreeText>
                    <Position></Position>
                    <Size></Size>
                    <LogoId></LogoId>
                </WaterMarkInfo>
            </VideoWatermark>
        </Watermark>
    </ProfileInfo>

Answer 1

让生活更轻松，并使用库为您进行反序列化。一个通常推荐的，我使用的是Newtonsoft.Json，反序列化就像这样简单：

JsonConvert.DeserializeObject<RequestMetaDataXml>(jsonStringReceived);

Answer 2

你要修改一件事，json或DTO类，因为json有WaterMark，VideoWatermark等单个对象，而DTO类说这些是List类型对象。此外，您需要一个包装类，因为RequestMetaDataXml包装在另一个对象中。

包装类：

[DataContract]
public class Wrapper
{
    [DataMember(Name = "RequestMetaDataXml")]
    public RequestMetaDataXml RequestMetaDataXml { get; set; }
}

以及更改后的其他课程：

[DataContract]
public class RequestMetaDataXml
{
    [DataMember(Name = "Title")]
    public string Title { get; set; }

    [DataMember(Name = "ExpiryDate")]
    public string ExpiryDate { get; set; }

    [DataMember(Name = "AllowDownload")]
    public string AllowDownload { get; set; }

    [DataMember(Name = "IsShare")]
    public string IsShare { get; set; }

    [DataMember(Name = "IncludeMetadata")]
    public string IncludeMetadata { get; set; }

    [DataMember(Name = "IsReel")]
    public string IsReel { get; set; }

    [DataMember(Name = "IsSecuredPublish")]
    public string IsSecuredPublish { get; set; }

    [DataMember(Name = "Notifications")]
    public NotificationId Notifications { get; set; }

    [DataMember(Name = "CoverArt")]
    public CoverArt Coverart { get; set; }

    [DataMember(Name = "ProfileInfo")]
    public ProfileInfo Profileinfo { get; set; }
}


[DataContract]
public class NotificationId
{
    [DataMember(Name = "Id")]
    public string Id { get; set; }

    [DataMember(Name = "Type")]
    public string Type { get; set; }
}

[DataContract]
public class CoverArt
{
    [DataMember(Name = "UploadedFileName")]
    public string UploadedFileName { get; set; }
}

[DataContract]
public class ProfileInfo
{
    [DataMember(Name = "Watermark")]
    public WaterMark WaterMark { get; set; }
}

[DataContract]
public class WaterMark
{
    [DataMember(Name = "VideoWatermark")]
    public VideoWatermark VideoWatermark { get; set; }
}

[DataContract]
public class VideoWatermark
{
    [DataMember(Name = "WaterMarkInfo")]
    public WaterMarkInfo WaterMarkInfo { get; set; }
}

[DataContract]
public class WaterMarkInfo
{
    [DataMember(Name = "Type")]
    public string Type { get; set; }

    [DataMember(Name = "FreeText")]
    public string FreeText { get; set; }

    [DataMember(Name = "Position")]
    public string Position { get; set; }

    [DataMember(Name = "Size")]
    public string Size { get; set; }

    [DataMember(Name = "LogoId")]
    public string LogoId { get; set; }
}

您需要添加Newtonsoft.Json的引用，然后使用

 var wrapper = JsonConvert.DeserializeObject<Wrapper>(json);
 RequestMetaDataXml RequestMetaDataXml = wrapper.RequestMetaDataXml;

如果您不想将List更改为单个对象，则需要更新json并将List类型对象值的值放在[ ]括号中 e.g。

"Notifications": [{
        "Id": "checktest1@ssss.com",
        "Type": "ExtUser"
 }],

等等。

但无论如何你还需要那个Wrapper课程。

Answer 3

        var ser = new XmlSerializer(typeof(RequestMetaDataXml));
        var settings = new XmlSerializerNamespaces();
        settings.Add("", "");
        using (var sw = new StringWriter())
        {
            ser.Serialize(sw, o.RequestMetaDataXml, settings);
            var t = sw.ToString();
        }

如何将Json String反序列化为Custom DTO C＃对象？
