c# - cs0030 :Unable to generate a temporary class

Question

我有一个 Web 服务，当我尝试生成它的对象时出现以下错误。

"Unable to generate a temporary class (result=1).error CS0030: Cannot convert type 'ShortSell.ShortSellRQOriginDestinationInformationFlightSegment[]' to 'ShortSell.ShortSellRQOriginDestinationInformationFlightSegment'error CS0030: Cannot convert type 'ShortSell.ShortSellRSOriginDestinationOptionFlightSegment[]' to 'ShortSell.ShortSellRSOriginDestinationOptionFlightSegment'error CS0030: Cannot convert type 'ShortSell.ShortSellRQOriginDestinationInformationFlightSegment[]' to 'ShortSell.ShortSellRQOriginDestinationInformationFlightSegment'error CS0029: Cannot implicitly convert type 'ShortSell.ShortSellRQOriginDestinationInformationFlightSegment' to 'ShortSell.ShortSellRQOriginDestinationInformationFlightSegment[]'error CS0029: Cannot implicitly convert type 'ShortSell.ShortSellRSOriginDestinationOptionFlightSegment' to 'ShortSell.ShortSellRSOriginDestinationOptionFlightSegment[]'error CS0029: Cannot implicitly convert type 'ShortSell.ShortSellRSOriginDestinationOptionFlightSegment' to 'ShortSell.ShortSellRSOriginDestinationOptionFlightSegment[]'"}

我尝试将临时文件夹属性更改为可写，但我仍然收到此错误。为什么会出现此错误，我该如何解决？

Answer 1

这是一个无法修复的已知错误:

• 微软连接:XmlSerializer Code Generation component cannot handle nested unbounded elements when there is only one element

当 wsdl 中的复杂类型恰好包含一个无限出现的元素时，就会发生错误。解决方法，取自 this forum discussion (归功于 Elena Kharitidi)，是为此类类型添加虚拟属性:

<xs:sequence maxOccurs="unbounded">
  <xs:element ../>
<xs:sequence>
<xs:attribute name="tmp" type="xs:string" />      <-- add this

和

<xs:sequence>
  <xs:element maxOccurs="unbounded"/>
<xs:sequence>
<xs:attribute name="tmp" type="xs:string" />      <-- add this
