Comment désérialiser XML en objet

Question

Je suis en train de suivre ce code, mais je ne peux pas accéder aux données XML.

Je voudrais désérialiser le XML suivante et classe d'objets en C#:

fichier XML est:

<EmployeeCollection> 
    <EmployeeDetail> 
    <Employee ID ="EMP-01"> 
     <Name>ABC</Name> 
     <MobileNumber></MobileNumber> 
     <Age>20</Age> 
     <Gender>Male</Gender> 
     <MartialStatus>Single</MartialStatus> 
     <DOB>1997-01-12</DOB> 
     <Branch Name="XYZ"> 
      <CountryCode>IND</CountryCode> 
      <EstablishmentDate>2013-01-15</EstablishmentDate> 
     </Branch> 
    </Employee> 
    <Employee ID ="EMP-02"> 
     <Name>DEF</Name> 
     <MobileNumber>9685741236</MobileNumber> 
     <Age>19</Age> 
     <Gender>Male</Gender> 
     <MartialStatus>Single</MartialStatus> 
     <DOB>19998-12-21</DOB> 
     <Branch Name="PQR"> 
      <CountryCode>US</CountryCode> 
      <EstablishmentDate>2011-01-23</EstablishmentDate> 
     </Branch> 
    </Employee> 
    </EmployeeDetail> 
</EmployeeCollection> 

Je cette:

public class Employee 
{ 
    [XmlAttribute("ID")] 
    public string ID    { get; set; } 

    [XmlElement("Name")] 
    public string Name    { get; set; } 

    [XmlElement("MobileNumber")] 
    public long MobileNumber  { get; set; } 

    [XmlElement("Age")] 
    public int Age     { get; set; } 

    [XmlElement("Gender")] 
    public string Gender   { get; set; } 

    [XmlElement("MartialStatus")] 
    public string MartialStatus  { get; set; } 

    [XmlElement("DOB")] 
    public DateTime DOB     { get; set; } 

    [XmlArray("Branch")] 
    public BranchDetail[] Branch { get; set; } 
} 

public class BranchDetail 
{ 
    [XmlAttribute("Name")] 
    public string BranchName  { get; set; } 

    [XmlElement("CountryCode")] 
    public string CountryCode  { get; set; } 

    [XmlElement("EstablishmentDate")] 
    public DateTime EstablishmentDate { get; set; } 
} 

[XmlRoot("EmployeeDetail")] 
public class EmployeeCollection 
{ 
    [XmlArray("Employee")] 
    public Employee[] Employee  { get; set; } 
} 

Mon code est:

public class EmployeeSerializer 
{ 
    public void Deserialize() 
    { 
     EmployeeCollection Employees = null; 

     XmlSerializer serializer = new XmlSerializer(typeof(EmployeeCollection)); 

     StreamReader reader = new StreamReader(employee.xml); 

     Employees = (EmployeeCollection)serializer.Deserialize(reader); 

     reader.Close(); 

    } 
} 

Je souhaite stocker toutes les données xml dans Object.

J'ai essayé mais je ne peux pas accéder aux données xml.

Answer 1

Vous n'avez pas besoin XmlArray Attributs ici, vous cuold il suffit d'utiliser XmlElementAttribute:

[XmlRoot("EmployeeDetail")] 
public class EmployeeCollection 
{ 
    [XmlElementAttribute("Employee")] 
    public Employee[] Employee { get; set; } 
} 

Et la même chose de la propriété de la Direction:

[XmlElementAttribute("Branch")] 
public BranchDetail[] Branch { get; set; } 

Vous pouvez utiliser la fonction "Collage spécial" de Visual Studio pour générer du code C# pour votre xml.

Answer 2

D'abord, vous pouvez utiliser un outil en ligne comme celui-ci:

http://www.freeformatter.com/xsd-generator.html

Ensuite, vous obtenez un XSD où vous pouvez personnaliser tous les types:

<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
<xs:element name="EmployeeDetail"> 
    <xs:complexType> 
     <xs:sequence> 
      <xs:element name="Employee" maxOccurs="unbounded" minOccurs="0"> 
       <xs:complexType> 
        <xs:sequence> 
         <xs:element type="xs:string" name="Name"/> 
         <xs:element type="xs:long" name="MobileNumber"/> 
         <xs:element type="xs:byte" name="Age"/> 
         <xs:element type="xs:string" name="Gender"/> 
         <xs:element type="xs:string" name="MartialStatus"/> 
         <xs:element type="xs:date" name="DOB"/> 
         <xs:element name="Branch"> 
          <xs:complexType> 
           <xs:sequence> 
            <xs:element type="xs:string" name="CountryCode"/> 
            <xs:element type="xs:date" name="EstablishmentDate"/> 
           </xs:sequence> 
           <xs:attribute type="xs:string" name="Name" use="optional"/> 
          </xs:complexType> 
         </xs:element> 
        </xs:sequence> 
        <xs:attribute type="xs:string" name="ID" use="optional"/> 
       </xs:complexType> 
      </xs:element> 
     </xs:sequence> 
    </xs:complexType> 
</xs:element> 

MISE À JOUR suivantes vos changements:

Ici seulement à changer le champ Âge de xs: octet xs: int, même si un âge ne peut pas être aussi élevé:

      <xs:element type="xs:int" name="Age"/> 

Ensuite, vous pouvez ouvrir une invite de développeur et d'utiliser l'outil XSD.exe de Microsoft, et vous obtenir une classe C#:

xsd.exe /c Test.xsd 

Voici le résultat:
