To use C # to invoke the schema file to validate an XML document

The C # code is as follows:

voidMain () {stringerrormessage; Validatexml (@"C:\Tarena\Backup\ Database \xml\book.xml",@"C:\Tarena\Backup\ Database \xml\book.xsd", outerrormessage).    Dump (); Errormessage.dump ();}//Define Other methods and classes hereStatic BOOLValidatexml (stringXMLFile,stringSchemafile, out stringerrormessage) {    BOOLIsValid =true;//Validation Results    Try{XmlSchemaSet Schemaset=NewXmlSchemaSet (); Schemaset.add (NULL, schemafile);//Add schema validation filexmlreadersettings readersetting=Newxmlreadersettings (); Readersetting.validationtype= ValidationType.Schema;//Configuring authentication MethodsReadersetting.schemas=Schemaset; using(XmlReader XmlReader =xmlreader.create (xmlfile, readersetting)) {             while(Xmlreader.read ()) {}} errormessage=string.    Empty; }    Catch(Exception ex) {IsValid=false; ErrorMessage=Ex.    Message; }        returnIsValid;}

where the XML file

<?XML version= "1.0" encoding= "Utf-8"?><Booksxmlns= "Http://www.w3.org/2001/XMLSchema">  < BookID= "1">    <title>Journey</title>    <author>Wu Chengen</author>    < Price>10.99</ Price>    <pubdate>2010-01-01</pubdate>    <category>Literature Category</category>  </ Book>  < BookID= "2">    <title>Three kingdoms</title>    <author>Luo Guan Zhong</author>    < Price>20.99</ Price>    <pubdate>2010-02-01</pubdate>    <category>Literature Category</category>  </ Book>  < BookID= "3">    <title>Dream</title>    <author>Cao Xueqin</author>    < Price>30.99</ Price>    <pubdate>2010-03-01</pubdate>    <category>Literature Category</category>  </ Book>  < BookID= "4">    <title>Outlaws</title>    <author>Shi Naian</author>    < Price>40.99</ Price>    <pubdate>2010-04-01</pubdate>    <category>Literature Category</category>  </ Book></Books>

Validation file (Schema)

<?XML version= "1.0" encoding= "Utf-8"?><Xs:schemaattributeFormDefault= "unqualified"elementFormDefault= "qualified"targetnamespace= "Book.xsd"Xmlns:xs= "Http://www.w3.org/2001/XMLSchema">  <xs:elementname= "Books">    <Xs:complextype>      <xs:sequence>        <xs:elementmaxOccurs= "unbounded"name= "book">          <Xs:complextype>            <xs:sequence>              <xs:elementname= "title"type= "Xs:string" />              <xs:elementname= "Author"type= "Xs:string" />              <xs:elementname= "Price"type= "Xs:decimal" />              <xs:elementname= "pubdate"type= "Xs:date" />            </xs:sequence>          </Xs:complextype>        </xs:element>      </xs:sequence>    </Xs:complextype>  </xs:element></Xs:schema>
