我试图让一个WCF.net 4.0客户端使用NuSOAP/0.7.2(1.94)Web服务。首先,Web服务不是基于当前的SOA标准,所以我必须创建一个自定义编码器来处理ISO-8859-1消息编码。当我得到的回应,WCF抛出以下异常WCF .Net 4.0客户端反序列化回复消息体中的错误

“错误在反序列化的回复消息的身体”

当寻找在SOAP身上,我看到<SOAP-ENV:Body>... stream ...</SOAP-ENV:Body>

有没有人碰到这个错误来吗?任何反馈或正确方向的一个点将非常感激。这是我的第一个WCF到“非”WCF服务。

原来有在反序列化的日期,因为它以正确的格式是不是一个错误。我发现错误是在WCF客户端启用“详细”调试模式。

System.InvalidCastException:无法将类型System.Xml.XmlNode []的对象分配给System.DateTime类型的对象。

传统Web服务传回“xsd:date”的日期和时间为数据类型应为“xsd:dateTime”的日期和时间。

为了确认这是问题的原因,我向Web服务请求了两条记录,并在覆盖消息ReadMessage()方法中操作XML,并更改了自动生成的代理类。这纠正了这个问题,我知道这不是最终的解决方案。在联系旧版Web服务的作者之前,有没有人对Soap日期和日期时间格式有任何评论?

Maybe the following date is valid in Soap Version 1.1 with ISO-8859-1 encoding: 

<date xsi:type="xsd:date">2010-05-02 08:03:45</date> 

If it is, is this an issue using a custom encoder or was it really the date type/format in the soap body? Microsoft only accepted that date in the following format: 

<date xsi:type="xsd:dateTime">2010-05-02T08:03:45</date> 


    <customBinding> 
     <binding name="ISO8859Binding"> 
     <customTextMessageEncoding messageVersion="Soap11" encoding="ISO-8859-1" mediaType="text/xml" /> 
     <httpsTransport /> 
     </binding> 
     </customBinding> 

public override Message ReadMessage(Stream stream, int maxSizeOfHeaders, string contentType) 
{ 

    XmlReader reader = XmlReader.Create(stream); 
    XmlDocument doc = new XmlDocument(); 

    // Log to a file. 
    StreamWriter sw = new StreamWriter(@"C:\dump2.txt"); 

    doc.Load(reader); 
    doc.InnerXml = doc.InnerXml.Replace("xsd:date", "xsd:dateTime"); 
    doc.InnerXml = doc.InnerXml.Replace("2010-05-02 08:03:45", "2010-05-02T08:03:45"); 
    doc.InnerXml = doc.InnerXml.Replace("2010-05-02 12:38:06", "2010-05-02T12:38:06"); 

    sw.WriteLine(doc.InnerXml); 
    sw.Flush(); 
    sw.Close(); 

    byte[] buffer = System.Text.Encoding.Default.GetBytes(doc.InnerXml); 
    Stream test = new MemoryStream(buffer); 
    XmlReader reader2 = XmlReader.Create(test); 

    return Message.CreateMessage(reader2, maxSizeOfHeaders, this.MessageVersion); 

} 

再次感谢, 布伦南
