本文介绍了一个使用C#创建XML Schema (XSD) 的示例，该示例定义了一个包含书籍信息的基本结构，包括书名和出版社两个字段。

  private void button1_Click(object sender, System.EventArgs e) {
   XmlSchema Schema=new XmlSchema();
   XmlSchemaElement ElementBook=new XmlSchemaElement();
   Schema.Items.Add(ElementBook);
   ElementBook.Name="Book";
   XmlSchemaComplexType CType=new XmlSchemaComplexType();
   ElementBook.SchemaType=CType;
   XmlSchemaSequence Sequence=new XmlSchemaSequence();
   CType.Particle=Sequence;
   XmlSchemaElement ElementTitle=new XmlSchemaElement();
   ElementTitle.Name="Title";
   ElementTitle.SchemaTypeName=new XmlQualifiedName("string","http://www.w3.org/2001/XMLSchema");
   XmlSchemaElement ElementPublisher=new XmlSchemaElement();
   ElementPublisher.Name="Publisher";
   ElementPublisher.SchemaTypeName=new XmlQualifiedName("string","http://www.w3.org/2001/XMLSchema");
   Sequence.Items.Add(ElementTitle);
   Sequence.Items.Add(ElementPublisher);
   Schema.Compile(new ValidationEventHandler(ValidationHandler));
   System.IO.FileStream f=new FileStream(@"c:/1.xml",FileMode.CreateNew);
   Schema.Write(f);
   f.Close();
  }
  public static void ValidationHandler(object sender,ValidationEventArgs args) {
   MessageBox.Show("Schema Validation Failed.");
   MessageBox.Show(args.Message);
  }

生成的XSD为:

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="Book">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="Title" type="xs:string" />
        <xs:element name="Publisher" type="xs:string" />
      </xs:sequence>
    </xs:complexType>
</xs:element>
</xs:schema>
