我的XSD有问题。我的XSD包含一个xs:choice
来实现选择其中一种类型的选项。不应该允许选择No Type(或Null)!
<xs:complexType name="TypeAndValue">
<xs:choice minOccurs="1">
<xs:element minOccurs="1" name="SimpleType" nillable="false" type="SimpleDataTypeAndValue" />
<xs:element minOccurs="1" name="ArrayType" nillable="false" type="ArrayTypeAndValue" />
<xs:element minOccurs="1" name="ListType" nillable="false" type="ListTypeAndValue" />
<xs:element minOccurs="1" name="ClassType" nillable="false" type="IdentifierTypeAndValue" />
</xs:choice>
我已经通过xsd.exe从xsd创建了一个.cs文件。这工作正常,没有错误。但是,如果我尝试这样的XML文件,XML将被接受:
<?xml version="1.0"?>
<Block xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Class Identifier="Test">
<Declaration Identifier="List">
<TypeAndValue>
</TypeAndValue>
</Declaration>
</Class>
</Block>
我在选择时尝试了minOccurs="1"
和nillable="false"
,但是Schema接受了空TypeAndValue
块。
可能是我需要修改cs文件吗?
编辑: 这是完整的XSD:

答案 0 :(得分:1)
您的XML实际上 不 对您的XSD有效:
[错误] try.xml:9:24:cvc-complex-type.2.4.b:元素的内容 'TypeAndValue'不完整。 '{SimpleType,ArrayType, ListType,ClassType}'是预期的。
由于这符合您的期望,您应该怀疑验证XML的方法。确保您使用的是验证解析器并且已启用验证。
