WCF：WSDL第一種方法：生成錯誤類型的問題

Question

我目前正在創建一個WCF webservice，它應該與WS-I Basic Profile 1.1兼容。我使用wsdl-first方法（實際上是第一次），首先定義複雜類型的WSDL，然後使用svcutil.exe生成相應的服務器以及客戶端接口/代理。到目前爲止一切正常。然後我決定將錯誤添加到我的WSDL中。

使用svcutil重新生成成功，但後來我注意到，我生成的錯誤沒有我在我的xsd文件（由我的WSDL導入）中定義的屬性。

複雜的數據類型爲xsd

<?xml version="1.0" encoding="UTF-8"?> 
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    xmlns:tns="http://myprod.services.mycompany.com/groups_v1.xsd" 
    targetNamespace="http://myprod.services.mycompany.com/groupsfault_v1.xsd"> 

    <xsd:complexType name="groupsFault"> 
     <xsd:sequence> 
      <xsd:element name="code" type="xsd:int"/> 
      <xsd:element name="message" type="xsd:string"/> 
     </xsd:sequence> 
    </xsd:complexType> 

</xsd:schema> 

故障XSD定義

<?xml version="1.0" encoding="UTF-8"?> 
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    xmlns:tns="http://myprod.services.mycompany.com/groups_v1.xsd" 
    targetNamespace="http://myprod.services.mycompany.com/groups_v1.xsd"> 

    <xsd:complexType name="group"> 
     <xsd:sequence> 
      <xsd:element name="groupDescD" type="xsd:string" /> 
      <xsd:element name="groupDescI" type="xsd:string" /> 
      <xsd:element name="groupProtNr" type="xsd:string" /> 
     </xsd:sequence> 
    </xsd:complexType> 

</xsd:schema> 

WSDL同時使用上述的XSD的

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

這是正確的？我期望創建一個包含「code」和「message」s.t.屬性的對象。那麼你可以通過使用類似

... 
throw new FaultException<groupFault>(new groupFault { code=100, message="error" }); 
... 

把它（抱歉小寫類型定義，但是這會產生從WSDL碼）爲什麼沒有svcutil.exe的

生成這些屬性？ 網絡上的一些消息來源建議添加svcutil的選項/useSerializerForFaults選項。我試過了，它不起作用，給我一個例外，說明wsdl:portType聲明中缺少錯誤類型。然而，與其他幾個工具的驗證成功。

If you were trying to generate a client, this could be because the metadata docu

Answer 1

我覺得你的問題是，你需要添加將elementFormDefault =「合格」作爲屬性到xsd：您的WSDL的模式部件。這對我有效。

Answer 2

我可以給你一個錯誤的例子這是通過svcutil爲我正確生成（與/ useSerializerForFaults）：

<xsd:schema targetNamespace="http://myproduct.mycompany.com/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" /> 
    <xsd:complexType name="MyError"> 
    <xsd:sequence> 
     <!-- other stuff --> 
     <xsd:element name="description" type="xsd:string"/> 
    </xsd:sequence> 
    </xsd:complexType> 
</xsd:schema> 

是否有可能你是簡單的缺少你的類型的命名空間？

這是生成的代碼：

/// <remarks/> 
[System.CodeDom.Compiler.GeneratedCodeAttribute("svcutil", "3.0.4506.2152")] 
[System.SerializableAttribute()] 
[System.Diagnostics.DebuggerStepThroughAttribute()] 
[System.ComponentModel.DesignerCategoryAttribute("code")] 
[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://myproduct.mycompany.com/")] 
public partial class MyError 
{ 

    // other stuff 

    private string descriptionField; 

    /// <remarks/> 
    [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified, Order = 1)] 
    public string description 
    { 
    get 
    { 
     return this.descriptionField; 
    } 
    set 
    { 
     this.descriptionField = value; 
    } 
    } 
} 

這是我的全SvcUtil工具CMD行語句（注意，我產生一個給定現有服務的服務參考 - 但它不應該讓太多的在代碼生成方面的區別）：

svcutil /t:code /out:C:\MyRepository\GeneratedCode\MyServiceReference.cs /n:*,myproduct.mycompany.servicereference /UseSerializerForFaults C:\MyRepository\*.wsdl C:\MyRepository\*.xsd /config:C:\MyRepository\GeneratedCode\MyServiceReference.config
