【问题描述】：

我有问题如何创建一个类定义来序列化和反序列化具有相同结果的对象。

这个类定义：

 /// <remarks/>
    [System.SerializableAttribute()]
    [System.ComponentModel.DesignerCategoryAttribute("code")]
    [System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://hl7.org/fhir")]
    public partial class PatientName
    

        private PatientNameFamily familyField;

        private PatientNameGiven givenField;

        /// <remarks/>
        public PatientNameFamily family
        
            get
            
                return this.familyField;
            
            set
            
                this.familyField = value;
            
        

        /// <remarks/>
        public PatientNameGiven given
        
            get
            
                return this.givenField;
            
            set
            
                this.givenField = value;
            
        
    

    /// <remarks/>
    [System.SerializableAttribute()]
    [System.ComponentModel.DesignerCategoryAttribute("code")]
    [System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://hl7.org/fhir")]
    public partial class PatientNameFamily
    

        private string valueField;

        /// <remarks/>
        [System.Xml.Serialization.XmlAttributeAttribute()]
        public string value
        
            get
            
                return this.valueField;
            
            set
            
                this.valueField = value;
            
        
    

    /// <remarks/>
    [System.SerializableAttribute()]
    [System.ComponentModel.DesignerCategoryAttribute("code")]
    [System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://hl7.org/fhir")]
    public partial class PatientNameGiven
    

        private string valueField;

        /// <remarks/>
        [System.Xml.Serialization.XmlAttributeAttribute()]
        public string value
        
            get
            
                return this.valueField;
            
            set
            
                this.valueField = value;
            
        
    

[System.SerializableAttribute()]
    [System.ComponentModel.DesignerCategoryAttribute("code")]
    [System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://hl7.org/fhir")]
    public partial class PatientNameFamily
    

        private string valueField;

        /// <remarks/>
        [System.Xml.Serialization.XmlAttributeAttribute()]
        public string value
        
            get
            
                return this.valueField;
            
            set
            
                this.valueField = value;
            
        
    

    /// <remarks/>
    [System.SerializableAttribute()]
    [System.ComponentModel.DesignerCategoryAttribute("code")]
    [System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://hl7.org/fhir")]
    public partial class PatientNameGiven
    

        private string valueField;

        /// <remarks/>
        [System.Xml.Serialization.XmlAttributeAttribute()]
        public string value
        
            get
            
                return this.valueField;
            
            set
            
                this.valueField = value;
            
        
    

将正确的序列化为 XML，如下所示：

<name>      
<family value="Senior"/>  
<given value="Sylwester"/>
</name>

但是当尝试反序列化 JSON 时： \"family\": \"Seniorka\",\"given\": [ \"Sylwia\" ] ] 我有例外：

将值“Seniorka”转换为类型“PlatformaP1ATD.ZM.PatientNameFamily”时出错，当然我可以将类定义更改为字符串和字符串数组，但我不想让两个类从 JSON 序列化为 xml 和反序列化。

知道如何将字符串值转换为嵌套类型吗？

【参考方案1】：

尝试以下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;

namespace ConsoleApplication1

    class Program
    
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        
            Name name = new Name()  family = new Family()  value = "Senior" , given = new Given()  value = "Sylwester"  ;

            XmlWriterSettings settings = new XmlWriterSettings();
            settings.Indent = true;
            XmlWriter writer = XmlWriter.Create(FILENAME, settings);
            XmlSerializer serializer = new XmlSerializer(typeof(Name));
            serializer.Serialize(writer, name);
        
    
    [XmlRoot("name")]
    public class Name
    
        public Family family  get; set; 
        public Given given  get; set; 
    
    public class Family
    
        [XmlAttribute()]
        public string value  get; set; 
    
    public class Given
    
        [XmlAttribute()]
        public string value  get; set; 
    

【讨论】：

对象到 XML 看起来不错，但从 String jsonString = "\"family\": \"Seniorka\",\"given\": [ \"Sylwia\" ] "; 来看同样的错误

看起来你只需要删除方括号。
