Mono wsdl 实用程序无法处理 eBay 的 SOAP API 的 WSDL 文件

我在尝试处理 eBay 的 WSDL 文件时从 Mono 的 wsdl 实用程序收到此错误 -

( http://developer.ebay.com/webservices/latest/eBaySvc.wsdl )

$ wsdl eBaySvc.wsdl 
Web Services Description Language Utility
Mono Framework v2.0.50727.1433
Error: XmlSchema error: Ambiguous element label which is contained by -any- particle was detected: urn:ebay:apis:eBLBaseComponents:PreferenceLevel Related schema item SourceUri: file:///home/manger/projects/ebay/eBaySvc.orig.wsdl, Line 10296, Position 7.

在 Google 中搜索解决方案显示了更改元素的建议，这些元素开头为 <xs:any ... 到 <xs:any namespace="##other" ... - 这无疑使得 Mono 的 wsdl 实用程序能够处理该文件，并从中创建 .cs 文件。但是当我尝试实例化 webservice 帮助程序类时，我的 C# 程序出现运行时异常（ eBayAPIInterfaceService service = new eBayAPIInterfaceService(); ) :

是 Mono 的 wsdl 工具有问题，还是 eBay 的 WSDL/模式有问题？- 我看到的几个论坛帖子都说 WSDL 与架构不匹配，因此 Mono 正在做正确的事情，但我该如何修复它以便可以从 C# 实例化 Web 服务帮助程序类？

我的工具的版本：

$ WSDL Web服务说明语言实用程序单框架v2.0.50727.1433

$ GMCS - Version Mono C＃编译器版本2.4.2.3

为 ErrorParameterType 生成的代码：

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "2.0.50727.1433")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace="urn:ebay:apis:eBLBaseComponents")]
public partial class ErrorParameterType {

    private System.Xml.XmlElement[] anyField165;

    ... more class members follow ...

    /// <remarks/>
    [System.Xml.Serialization.XmlAnyElement(Namespace="")]
    public System.Xml.XmlElement[] Any {
        get {
            return this.anyField165;
        }
        set {
            this.anyField165 = value;
        }
    }
}

我的“修复”后 wsdl 生成的 eBayAPIInterfaceService.cs 文件是 这里

有帮助吗？

解决方案

我不知道是否能解决你的问题，但 xs:any通配符你的问题是缺席两场'#'：

<xs:any namespace="##other" ...
                   ↑

生成的C＃代码包含大量的定义是这样的：

[System.Xml.Serialization.XmlAnyElement(Namespace="")]
public System.Xml.XmlElement[] Any {
    get {
        return this.anyFieldXXX;
    }
    set {
        this.anyFieldXXX = value;
    }
}

从 MSDN ：

  

应用XmlAnyElementAttribute到返回XmlElement或XmlNode对象的阵列的场。这样的域可以以两种方式使用，这取决于对象是否被序列化或反序列化。当序列，该目的为XML元素或节点生成的，即使它们具有在对象没有对应的构件（或部件）被序列化。如果在应用属性时指定Name属性值，插入阵列的所有XmlElement或XmlNode对象必须有相同的元素名称和默认命名空间，或抛出一个异常。 如果您设置的Namespace属性值，你必须设置Name属性以及和XmlElement或XmlNode对象还必须具有相同的名称和命名空间值。如果没有指定Name值，则XmlElement或XmlNode对象可以有任何元素名称。

所以我猜的解决方案是简单地去掉Namespace属性值：

[System.Xml.Serialization.XmlAnyElement]
