Why use XSD file to create C# classes？
当应用场景是这样的：
1． 需要定义大量的自定义格式的XML协议，供通讯双方使用，本文基于内部接口测试工具的测试协议格式。
2． 减少中间依赖关系，类依赖于XML协议的格式，而非用CS文件序列化XML文件。
How to convert XML file to XSD file?
准备一个支持W3C标准的XML文件（必须有文件头<?xml version="1.0" encoding="utf-8"?>）
<?xml version="1.0" encoding="utf-8" ?> <protobuftest> <head> <version>1.0.0</version> <description>Bocode protobuf test protocol</description> </head> <transaction> <name>Transaction 01</name> <items> <item> <name>Functional Test 01</name> <description>Test protobuf demo</description> <testinput> <code>4002</code> </testinput> <testparams> <usepretest>false</usepretest> <keystring> <key>10005</key> <value>100</value> <pindex>0</pindex> </keystring> <keybytes> <key>10007</key> <value>12jkjk123jk12312k312k3k1221k3jk21123213k3k13k1</value> <pindex>0</pindex> </keybytes> <keylist> <keystring> <key>30002</key> <value>0</value> <pindex>0</pindex> </keystring> <keystring> <key>30002</key> <value>10</value> <pindex>0</pindex> </keystring> <keystring> <key>30002</key> <value>10</value> <pindex>0</pindex> </keystring> </keylist> </testparams> <testoutput> <resultcode>0</resultcode> </testoutput> </item> <item> <name>Functional Test 02</name> <description>Test protobuf demo</description> <testinput> <code >4002</code> </testinput> <testparams> <keystring> <key>10005</key> <value>100</value> </keystring> <keybytes> <key>10007</key> <value>12jkjk123jk12312k312k3k1221k3jk21123213k3k13k1</value> </keybytes> <keylist> <keystring> <key>30002</key> <value>0</value> </keystring> <keystring> <key>30002</key> <value>10</value> </keystring> <keystring> <key>30002</key> <value>10</value> </keystring> </keylist> </testparams> <testoutput> <resultcode>0</resultcode> </testoutput> </item> </items> </transaction> </protobuftest>
以文件方式保存在XXX路径下，并启动VS2012 ARM Cross Tools Command Prompt
之后在XXX目录下即生成ProtobufTest_Demo.xsd文件
How to create C# file by XSD file?
首先准备一个xsd文件，保存在XXX路径，命名为ProtobufTest_Demo.xsd
<?xml version="1.0" encoding="utf-8"?> <xs:schema id="protobuftest" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"> <xs:element name="keystring"> <xs:complexType> <xs:sequence> <xs:element name="key" type="xs:string" minOccurs="0" /> <xs:element name="value" type="xs:string" minOccurs="0" /> <xs:element name="pindex" type="xs:string" minOccurs="0" /> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="protobuftest" msdata:IsDataSet="true" msdata:Locale="en-US"> <xs:complexType> <xs:choice minOccurs="0" maxOccurs="unbounded"> <xs:element ref="keystring" /> <xs:element name="head"> <xs:complexType> <xs:sequence> <xs:element name="version" type="xs:string" minOccurs="0" /> <xs:element name="description" type="xs:string" minOccurs="0" /> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="transaction"> <xs:complexType> <xs:sequence> <xs:element name="name" type="xs:string" minOccurs="0" /> <xs:element name="items" minOccurs="0" maxOccurs="unbounded"> <xs:complexType> <xs:sequence> <xs:element name="item" minOccurs="0" maxOccurs="unbounded"> <xs:complexType> <xs:sequence> <xs:element name="name" type="xs:string" minOccurs="0" /> <xs:element name="description" type="xs:string" minOccurs="0" /> <xs:element name="testinput" minOccurs="0" maxOccurs="unbounded"> <xs:complexType> <xs:sequence> <xs:element name="code" type="xs:string" minOccurs="0" /> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="testparams" minOccurs="0" maxOccurs="unbounded"> <xs:complexType> <xs:sequence> <xs:element name="usepretest" type="xs:string" minOccurs="0" /> <xs:element ref="keystring" minOccurs="0" maxOccurs="unbounded" /> <xs:element name="keybytes" minOccurs="0" maxOccurs="unbounded"> <xs:complexType> <xs:sequence> <xs:element name="key" type="xs:string" minOccurs="0" /> <xs:element name="value" type="xs:string" minOccurs="0" /> <xs:element name="pindex" type="xs:string" minOccurs="0" /> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="keylist" minOccurs="0" maxOccurs="unbounded"> <xs:complexType> <xs:sequence> <xs:element ref="keystring" minOccurs="0" maxOccurs="unbounded" /> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="testoutput" minOccurs="0" maxOccurs="unbounded"> <xs:complexType> <xs:sequence> <xs:element name="resultcode" type="xs:string" minOccurs="0" /> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:choice> </xs:complexType> </xs:element> </xs:schema>
然后打开VS2012 Command Prompt（开始---所有程序---Microsoft Visual Studio 2012---Visual Studio Tools---VS2012 ARM Cross Tools Command Prompt）
（文中TestXSD为ProtobufTest_Demo.xsd路径， /classes为输出类型， /language：CS为输出语言）
打开 ProtobufTest_Demo.cs文件：
