Question

我有一个Web服务（用PHP创建），当我尝试使用.NET WebService Studio（但也使用Storm）使用此服务时，我遇到了问题。

有问题的数据类型在单独的文件中定义如下：

<simpleType name="Country">
  <restriction base="string">
    <minLength value="1" />
    <maxLength value="3" />
  </restriction>
</simpleType>

<complexType name="SecarPOISearchResult">
  <complexContent>
    <extension base="search:ngSearchResult">
      <sequence>
        <element name="ID_UserPOI" type="int" minOccurs="0" maxOccurs="1" />
        <element name="ID_Firm" type="int" minOccurs="0" maxOccurs="1" />
        <element name="ID_Department" type="int" minOccurs="0" maxOccurs="1" />
        <element name="ID_Country" type="tns:Country" minOccurs="0" maxOccurs="1" />
      </sequence>
    </extension>
  </complexContent>
</complexType>

使用此声明时，我总是收到错误：

当我从tns切换元素Country的类型时会发生有趣的情况：Country to string - 一切正常。同样的情况在另一种类型中稍早发生 - 再次使用union的simpleType（int和字符串，限制枚举仅为星号）。当我用简单的字符串替换这个类型时，这个错误消失了（并且用ID_Country元素发生了另一个错误）。

SOAP响应没问题，但.NET无法解析响应。这是一个已知的.NET错误吗？
