您可以使用XSD.exe（可从Visual Studio安装中获得。）
public sealed class Configuration
{
public string Name { get; set; }
public Levels Level { get; set; }
public ConfigurationSpec Spec { get; set; }
}
public abstract class ConfigurationSpec { }
public class ConfigurationSpec1 { }
public class ConfigurationSpec2 { }
结果是
<?xml version="1.0" encoding="utf-8"?>
<xs:schema elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="Levels" type="Levels" />
<xs:simpleType name="Levels">
<xs:restriction base="xs:string">
<xs:enumeration value="Easy" />
<xs:enumeration value="Medium" />
<xs:enumeration value="Hard" />
</xs:restriction>
</xs:simpleType>
<xs:element name="Configuration" nillable="true" type="Configuration" />
<xs:complexType name="Configuration">
<xs:sequence>
<xs:element minOccurs="0" maxOccurs="1" name="Name" type="xs:string" />
<xs:element minOccurs="1" maxOccurs="1" name="Level" type="Levels" />
<xs:element minOccurs="0" maxOccurs="1" name="Spec" type="ConfigurationSpec" />
</xs:sequence>
</xs:complexType>
<xs:complexType name="ConfigurationSpec" abstract="true" />
<xs:element name="ConfigurationSpec" nillable="true" type="ConfigurationSpec" />
<xs:element name="ConfigurationSpec1" nillable="true" type="ConfigurationSpec1" />
<xs:complexType name="ConfigurationSpec1" />
<xs:element name="ConfigurationSpec2" nillable="true" type="ConfigurationSpec2" />
<xs:complexType name="ConfigurationSpec2" />
</xs:schema>
您要做的就是编译程序集，并XSD.exe以程序集的路径作为参数运行。XSD.exe /?也具有所有参数的列表。
例： XSD.exe C:\Dev\Project1\Bin\Debug\library.dll
