无法将JSON响应字符串解析为XML

本文关键字：XML 字符串 响应 JSON | 更新日期: 2023-09-27 17:58:37

我的web服务正在使用对象到XML序列化程序提供格式化为XML的json字符串。我的回答是：

public static string ObjectToXmlString(this Object obj)
    {
        string xmlStr = string.Empty;
        XmlSerializer xs = new XmlSerializer(obj.GetType());
        XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
        ns.Add("", "");
        using (MemoryStream memoryStream = new MemoryStream())
        {
            XmlWriterSettings settings = new XmlWriterSettings()
            {
                Encoding = Encoding.UTF8,
                Indent = false,
                OmitXmlDeclaration = true,
                NewLineChars = string.Empty,
                NewLineHandling = NewLineHandling.None
            };
            using (XmlWriter writer = XmlWriter.Create(memoryStream, settings))
            {
                xs.Serialize(writer, obj,ns);
            }
            return Encoding.UTF8.GetString(memoryStream.ToArray()).Replace("'"", string.Empty);
        }
    }

服务响应：

 "<ArrayOfOwnerShipDetails><OwnerShipDetails><OwnerShipId>80932</OwnerShipId><FileNumber>rp1144</FileNumber><Salutation>Mr</Salutation><OwnerFirstName>Jai Kumar Datwni ji</OwnerFirstName><OwnerMiddleName /><OwnerLastName /><ResidentialAddress>1159 Sec 18 C,c Hd</ResidentialAddress><EmailID /><MobileNumber /><VoterID /><AadharCardNo /><RelationCode>S</RelationCode><RelationDescription>Son of</RelationDescription><FatherOrHusbandName>Lachman Dass S</FatherOrHusbandName><PropertyShareInPercentage>50.00</PropertyShareInPercentage><AdditionalRemarks /></OwnerShipDetails></ArrayOfOwnerShipDetails>"

但当我尝试将这个json响应解析到我调用服务的其他应用程序时。

using (var client = new HttpClient())
                {
                    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/xml"));
                    var response = client.GetAsync("http://localhost:50429/api/Haris/GetOwnersByFileNo?fileNo=RP1144").Result;
                    if (response.IsSuccessStatusCode)
                    {
                        // by calling .Result you are performing a synchronous call
                        var responseContent = response.Content;
                        // by calling .Result you are synchronously reading the result
                        string responseString = responseContent.ReadAsStringAsync().Result.Trim();

                        // Create the XmlDocument.
                        XmlDocument doc = new XmlDocument();
                        **doc.LoadXml(responseString ); ---> Error Comes here**

                    }
                }

它会出错根级别的数据无效。第1行，位置1

但若我把同样的回复复制到记事本上，然后在运行时粘贴到变量上，效果会很好。json字符串中的双引号有什么问题吗。

请帮帮我。

改为使用Load()方法，它将解决问题。查看更多

否则

doc.LoadXml(responsestring.Substring(responsestring.IndexOf(Environment.NewLine)));

实时演示

通过将字符串转换为蒸汽并再次转换为字符串，最终得到了解决方案：

 string sb = responseString;
                         sb = responseString.Replace("'"", string.Empty).Trim().ToString().Trim();
                         var a = GenerateStreamFromString(sb);
                         StreamReader reader = new StreamReader(a);
                         string text = reader.ReadToEnd();
                        XmlDocument doc = new XmlDocument();
                        doc.LoadXml(responseString);
