关于C#读取Xml架构文件的问题

Question

http://dotnet.aspx.cc/article/7b4c7a42-4cdf-40d1-b293-e86da109a34c/read.aspx跟普通的XML文档的区别就是他是带命名空间的

Answer 1

//读写 XML 架构
using System;
using System.IO;
using System.Text;
using System.Xml;
using System.Xml.Schema;class XmlSchemaReadWriteExample

    static void Main()

            foreach (XmlSchemaElement childElement in sequence.Items)

Answer 2

XmlSchemaSet   在2.0里才有
在前面的版本里是没有的，我用的VS2003，net Framework版本非2.0

Answer 3

直接用XMLREADER或是XMLDOCUMENT解决不了吗?

Answer 4

下面的应该2003支持的
//生成XmlSchema
private const String document = "sample.xsd";
XmlSchema mySchema = XmlSchema.Read(new XmlTextReader(document));myXmlTextWriter = new XmlTextWriter(Console.Out);
myXmlTextWriter.Formatting = Formatting.Indented;
myXmlTextWriter.Indentation = 2;// Write out the XSD
    void WriteXSDSchema()
    {
        myXmlTextWriter.WriteStartElement("schema", XmlSchema.Namespace);
        myXmlTextWriter.WriteAttributeString("targetNamespace", myXmlSchema.TargetNamespace);
        foreach(XmlSchemaInclude include in myXmlSchema.Includes)
        {
            myXmlTextWriter.WriteStartElement("include", XmlSchema.Namespace);
            myXmlTextWriter.WriteAttributeString("schemaLocation", include.SchemaLocation);
            myXmlTextWriter.WriteEndElement();
        }        foreach(object item in myXmlSchema.Items)
        {
            if (item is XmlSchemaAttribute)
                WriteXmlSchemaAttribute((XmlSchemaAttribute)item);      //attribute
            else if (item is XmlSchemaComplexType)
                WriteXmlSchemaComplexType((XmlSchemaComplexType)item);  //complexType
            else if (item is XmlSchemaSimpleType)
                WriteXmlSchemaSimpleType((XmlSchemaSimpleType)item);    //simpleType
            else if (item is XmlSchemaElement)
                WriteXmlSchemaElement((XmlSchemaElement)item);          //element
            else if (item is XmlSchemaAnnotation)
                WriteXmlSchemaAnnotation((XmlSchemaAnnotation)item);    //annotation
            else if (item is XmlSchemaAttributeGroup)
                WriteXmlSchemaAttributeGroup((XmlSchemaAttributeGroup)item); //attributeGroup
            else if (item is XmlSchemaNotation)
                WriteXmlSchemaNotation((XmlSchemaNotation)item);        //notation
            else if (item is XmlSchemaGroup)
                WriteXmlSchemaGroup((XmlSchemaGroup)item);              //group
            else
                Console.WriteLine("Not Implemented.");
        }
        myXmlTextWriter.WriteEndElement();
    }
