XML枚举类型enum反序列化以及xsd属性限定（C#）

下面是类的设置，包含enum类型IterationTypes。序列化和反序列化可直接将xml中的对应字符串反序列化为enum对象。

namespace MoscaCore.Models
{
    public enum IterationTypes
    {
        [XmlEnum(Name = "IOIteration")]
        IOIteration = 0,
        [XmlEnum(Name = "NodeIteration")]
        NodeIteration = 1,
        [XmlEnum(Name = "FieldIteration")]
        FieldIteration = 2,
    }
 
    public class Iteration
    {
        private IterationTypes iterationType = IterationTypes.IOIteration;//默认的迭代方法
        [XmlAttribute("IterationType")]
        public IterationTypes IterationType
        {
            get { return iterationType; }
            set { iterationType = value; }
        }
 
        private int maxIteration = 20;
        [XmlAttribute("MaxIteration")]
        public int MaxIteration
        {
            get { return maxIteration; }
            set { maxIteration = value; }
        }
 
        private double sigma = 100;
        [XmlAttribute("Sigma")]
        public double Sigma
        {
            get { return sigma; }
            set { sigma = value; }
        }
 
    }
}

在编辑xml的时候可以直接输入enum对应的string了，如下：

<iteration iterationtype="NodeIteration" maxiteration="20" sigma="100"></iteration>

对应的xsd限定写法如下：

<xs:element name="Iteration">
  <xs:complextype>
  
    <xs:attribute name="MaxIteration" type="xs:int">
    <xs:attribute name="Sigma" type="xs:double">
  
    <xs:attribute name="IterationType">          
      <xs:simpletype>
        <xs:restriction base="xs:string">
          <xs:enumeration value="IOIteration">
          <xs:enumeration value="NodeIteration">
          <xs:enumeration value="FieldIteration">
        </xs:enumeration></xs:enumeration></xs:enumeration></xs:restriction>
      </xs:simpletype>
    </xs:attribute>
                       
  </xs:attribute></xs:attribute></xs:complextype>
</xs:element>
