C# xsd架构错误找到以元素开头的无效内容，此时不需要子元素

我正在针对输入xml创建一个模式，其中我的主要要求是将

ParcelNumber

或

WorkArea

设置为必填项，因此这里是我的输入xml

<?xml version="1.0" encoding="utf-8"?>
<NOCPlantMapRequest xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <NOCTypeID>0</NOCTypeID>
  <WorkLocation>
    <ParcelNumber>4545</ParcelNumber>
    <Roads>
      <WorkLocationRoad>
        <RoadName>chennai road</RoadName>
      </WorkLocationRoad>
    </Roads>
    <WorkArea>
      <WorkArea>
        <Coordinates>
          <WorkLocationCoordinate>
            <CoordinateX>56</CoordinateX>
            <CoordinateY>23</CoordinateY>
          </WorkLocationCoordinate>
        </Coordinates>
        <Communities />
      </WorkArea>
    </WorkArea>
  </WorkLocation>
</NOCPlantMapRequest>

---

我在.xsd中检查了visual studio和

，LocationType只接受ParcelNumber或工作区，找不到道路或社区

在xsd:choice中包含2个xsd:sequences也有点不寻常，通常您只需执行以下操作：

<xsd:complexType name="LocationType">
  <xsd:all>
    <xsd:element name="ParcelNumber" type="ParcelNumberType" maxOccurs="1"/>
    <xsd:element name="WorkArea" type="WorkAreaType" maxOccurs="1"/>
  </xsd:all>
</xsd:complexType>

这是一个完整的XSD，应该验证您的XML示例：

是吗？如果Abel非常擅长帮你解决XSD问题，但他在那里来回奔波，无法解决你的问题，你应该重新审视一下自己。你是一名冠军，让我做进一步的测试，尽管最初的测试是成功的，但在接受答案之前
