序列内的XML Schema上下文类型

Question

我正在使用C＃创建XML Schema，但是我发现了一个奇怪的标签序列，之前从未使用过。 我希望它看起来像这样：

<xsd:complexType name="Sensor_Info">
<xsd:sequence>
    <xsd:element name="Sensor" minOccurs="1" maxOccurs="unbounded">
        <xsd:complexType>   
            <xsd:attribute name="id" type="xsd:string"/>
            <xsd:attribute name="name" type="xsd:string"/>
            <xsd:attribute name="type" type="xsd:string"/>
            <xsd:attribute name="location_id" type="xsd:string"/>
            <xsd:attribute name="unit" type="xsd:string"/>
            <xsd:attribute name="min_value" type="xsd:int"/>
            <xsd:attribute name="max_value" type="xsd:int"/>
        </xsd:complexType>
    </xsd:element>
</xsd:sequence>
<xsd:attribute name="count" type="xsd:int"/>

如果您能帮助我，我表示感谢：）

您最好的朋友是MSDN。我在下面显示的是XmlSchema文档页面的改编示例。 基本上，链接SOM API调用的方式与XSD结构相同。

using System;
using System.Xml;
using System.Xml.Schema;

class XMLSchemaExamples
{
    public static void Main()
    {

        XmlSchema schema = new XmlSchema();

        var ct = new XmlSchemaComplexType {Name = "Sensor_Info"};
        schema.Items.Add(ct);

        var at = new XmlSchemaAttribute
        {
            Name = "count",
            SchemaTypeName = new XmlQualifiedName("int", XmlSchema.Namespace)
        };
        ct.Attributes.Add(at);

        var seq = new XmlSchemaSequence();
        ct.Particle = seq;

        var sensor = new XmlSchemaElement {Name = "Sensor", MaxOccursString = "unbounded"};
        seq.Items.Add(sensor);
        var sensorType = new XmlSchemaComplexType();
        sensor.SchemaType = sensorType;

        at = new XmlSchemaAttribute
        {
            Name = "id",
            SchemaTypeName = new XmlQualifiedName("string", XmlSchema.Namespace)
        };
        sensorType.Attributes.Add(at);
        // TODO add more attributes here

        XmlSchemaSet schemaSet = new XmlSchemaSet();
        schemaSet.ValidationEventHandler += ValidationCallbackOne;
        schemaSet.Add(schema);
        schemaSet.Compile();

        var nsmgr = new XmlNamespaceManager(new NameTable());
        nsmgr.AddNamespace("xsd", "http://www.w3.org/2001/XMLSchema");
        schema.Write(Console.Out, nsmgr);
    }

    public static void ValidationCallbackOne(object sender, ValidationEventArgs args)
    {
        Console.WriteLine(args.Message);
    }
}
