每个人。我需要用内部元素序列化对象，这些元素可以出现多次，并且每个元素都是数组。例如

<Entity_Spatial Ent_Sys="ID0">
        <Spatial_Element>
          <Spelement_Unit Type_Unit="Точка">
            <NewOrdinate X="1234567890123456789" Y="1234567890123456789" Num_Geopoint="1073741824"/>
          </Spelement_Unit>
          <Spelement_Unit Type_Unit="Точка">
            <NewOrdinate X="1234567890123456789" Y="1234567890123456789" Num_Geopoint="1073741824"/>
          </Spelement_Unit>
          <Spelement_Unit Type_Unit="Точка">
            <NewOrdinate X="1234567890123456789" Y="1234567890123456789" Num_Geopoint="1073741824"/>
          </Spelement_Unit>
          <Spelement_Unit Type_Unit="Точка">
            <NewOrdinate X="1234567890123456789" Y="1234567890123456789" Num_Geopoint="1073741824"/>
          </Spelement_Unit>
        </Spatial_Element>
        <Spatial_Element>
          <Spelement_Unit Type_Unit="Точка">
            <NewOrdinate X="1234567890123456789" Y="1234567890123456789" Num_Geopoint="1073741824"/>
          </Spelement_Unit>
          <Spelement_Unit Type_Unit="Точка">
            <NewOrdinate X="1234567890123456789" Y="1234567890123456789" Num_Geopoint="1073741824"/>
          </Spelement_Unit>
          <Spelement_Unit Type_Unit="Точка">
            <NewOrdinate X="1234567890123456789" Y="1234567890123456789" Num_Geopoint="1073741824"/>
          </Spelement_Unit>
          <Spelement_Unit Type_Unit="Точка">
            <NewOrdinate X="1234567890123456789" Y="1234567890123456789" Num_Geopoint="1073741824"/>
          </Spelement_Unit>
        </Spatial_Element>
      </Entity_Spatial>

visual studio的xsd.exe生成的类Entity_Spatial：

当我尝试序列化对象时出现问题。异常

"无法生成临时类(结果=1(。

错误CS0030:无法将类型"tSPELEMENT_UNIT_SHORT[]"转换为"tSPEELEMENT_UNIT_SHORT"。

错误CS0029:无法将类型"tSPELEMENT_UNIT_SHORT"转换为"tSPEELEMENT_UNIT_SHORT[]"。引发

我需要解决这个问题，但我无法更改xml模式。我该怎么办？

xml多数组元素序列化

尝试这个

public class Spatial_Element
{
    [XmlElement("Spelement_Unit")]
    public List<Spelement_Unit> units;
    public Spatial_Element()
    {
        units = new List<Spelement_Unit>();
    }
}
public class Spelement_Unit
{
    [XmlAttribute("Type_Unit")]
    public string type_unit;
    [XmlElement("NewOrdinate")]
    public NewOrdinate newOrdinate;
}
public class NewOrdinate
{
    [XmlAttribute("X")]
    public string X;
    [XmlAttribute("Y")]
    public string Y;
    [XmlAttribute("Num_Geopoint")]
    public string Num_Geopoint;
}
public class Entity_Spatial
{
    [XmlAttribute("Ent_Sys")]
    public string Ent_Sys;
    [XmlElement("Spatial_Element")]
    public List<Spatial_Element> Items;
    public Entity_Spatial()
    {
        Items = new List<Spatial_Element>();
    }
}

测试

Entity_Spatial es = new Entity_Spatial();
es.Ent_Sys = "ID0";
Spatial_Element se = new Spatial_Element();
Spelement_Unit unit = new Spelement_Unit();
NewOrdinate ordinate = new NewOrdinate();
unit.type_unit = "blabla";
ordinate.X = "500";
ordinate.Y = "800";
ordinate.Num_Geopoint ="1233";
unit.newOrdinate = ordinate;
se.units.Add(unit);
es.Items.Add(se);
XmlSerializer xs = new XmlSerializer(typeof(Entity_Spatial));
xs.Serialize(XmlWriter.Create(@"C:'asd.xml"), es);
Entity_Spatial es2 = (Entity_Spatial)xs.Deserialize(XmlReader.Create(@"C:'test.xml"));

更换

[System.Xml.Serialization.XmlArrayItemAttribute("Spelement_Unit", typeof(tSPELEMENT_UNIT_SHORT), IsNullable = false)]

在

[System.Xml.Serialization.XmlArrayItemAttribute("Spelement_Unit", typeof(tSPELEMENT_UNIT_SHORT[]), IsNullable = false)]
