Question

我正在尝试构建WPF程序，根据作为服务引用添加的WSDL将Soap请求创建为xml文件。
问题是我无法配置代理类来使用该xml文件并将其作为请求发送以及接收响应。它给了我一个例外：

类型＆System; Service.ServiceModel.FaultException`1＆＃39;的未处理异常发生在mscorlib.dll中附加信息：APPLICATION ERROR

public string returnSerializedxml(object input)
{
    XmlSerializer xmlSerializer = new XmlSerializer(input.GetType());

    using (StringWriter textWriter = new StringWriter())
    {
        xmlSerializer.Serialize(textWriter, input);
        return textWriter.ToString();
    }
}

private void button1_Click(object sender, RoutedEventArgs e)
{
    ConsignmentEndpointClient proxy = new ConsignmentEndpointClient();
    save sv = new save();
    saveResponse response = new saveResponse();
    XmlDocument doc = new XmlDocument();
    doc.Load(PATH);
    response= proxy.save(sv);  /*Here occur the exception*/

    try
    {
        Output.Text = "Response : \n" + returnSerializedxml(response);     
    }
    catch (Exception error)
    {
        Output.Text = "Error in Request : \n" + error;
    }

编辑代码以忽略不与webservice调用交互的对象给出：

ConsignmentEndpointClient proxy = new ConsignmentEndpointClient();
save sv = new save();
response= proxy.save(sv);  /*Here occur the exception*/

在不知道网络服务期望的情况下，它看起来就像你正在尝试保存一个全新的对象，这个对象没有以任何方式改变（可能是，也可能不是，有效的事情）。你没有处理它抛出的异常，这就是为什么它没有处理 - 你可以简单地将它移动到try块范围内的调用中，所以更像是：

private void button1_Click(object sender, RoutedEventArgs e)
{
    try
    {
        ConsignmentEndpointClient proxy = new ConsignmentEndpointClient();
        save sv = new save();

        throw new NotImplementedExcetpion("This probably needs to be associated with your sv object in some way, or just removed altogether");

        XmlDocument doc = new XmlDocument();
        doc.Load(PATH);
        saveResponse response = proxy.save(sv);  /*Here occur the exception*/

        Output.Text = "Response : \n" + returnSerializedxml(response);     
    }
    catch (Exception error)
    {
        Output.Text = "Error in Request : \n" + error;
    }
}

发送Soap请求并捕获响应
