C# WCF消息格式化程序未格式化错误消息

我有一个WCF服务，我正在更改肯定响应的前缀，但是在错误响应上，只有部分消息被更改

<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SOAP-ENV:Body>
    <s:Fault
        xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
        <faultcode>s:Client</faultcode>
        <faultstring xml:lang="en-GB">Unable to satisfy web service request at this time.This may relate to the format or sequence of the requests, the status of the requested information or reflect a service issue.</faultstring>
    </s:Fault>
</SOAP-ENV:Body>

我还需要去掉它的名称空间

我尝试过各种各样的事情，但都没有成功

下面是我尝试过的一种方法\方法的示例

protected override void OnWriteDetail(XmlDictionaryWriter writer)
{
    writer.WriteStartElement("Fault", "http://schemas.xmlsoap.org/soap/envelope/");
}

但是，这不是一个适合覆盖的方法

看过这里的一些文档后，我无法得到任何有用的东西

有关设置故障消息格式的任何和所有帮助都将非常有用

您可以尝试以下解决方案：

  public class CustomMessage : Message
    {
        private readonly Message message;

        public CustomMessage(Message message)
        {
            this.message = message;
        }
        public override MessageHeaders Headers
        {
            get { return this.message.Headers; }
        }
        public override MessageProperties Properties
        {
            get { return this.message.Properties; }
        }
        public override MessageVersion Version
        {
            get { return this.message.Version; }
        }
        protected override void OnWriteStartBody(XmlDictionaryWriter writer)
        {
            writer.WriteStartElement("Body", "http://schemas.xmlsoap.org/soap/envelope/");
        }
        protected override void OnWriteBodyContents(XmlDictionaryWriter writer)
        {
            this.message.WriteBodyContents(writer);
        }
        protected override void OnWriteStartEnvelope(XmlDictionaryWriter writer)
        {
            writer.WriteStartElement("SOAP-ENV", "Envelope", "http://schemas.xmlsoap.org/soap/envelope/");
            writer.WriteAttributeString("xmlns", "xsi", null, "http://www.w3.org/2001/XMLSchema-instance");
            writer.WriteAttributeString("xmlns", "xsd", null, "http://www.w3.org/2001/XMLSchema");
        }
    }

这是我的留言

public class MyCustomMessageFormatter : IDispatchMessageFormatter
    {
        private readonly IDispatchMessageFormatter formatter;

        public MyCustomMessageFormatter(IDispatchMessageFormatter formatter)
        {
            this.formatter = formatter;
        }

        public void DeserializeRequest(Message message, object[] parameters)
        {
            this.formatter.DeserializeRequest(message, parameters);
        }

        public Message SerializeReply(MessageVersion messageVersion, object[] parameters, object result)
        {
            var message = this.formatter.SerializeReply(messageVersion, parameters, result);
            return new CustomMessage(message);
        }
    }

这是MyCustomMessageFormatter

 [AttributeUsage(AttributeTargets.Method)]
    public class MyMessageAttribute : Attribute, IOperationBehavior
    {
        public void AddBindingParameters(OperationDescription operationDescription, BindingParameterCollection bindingParameters) { }

        public void ApplyClientBehavior(OperationDescription operationDescription, ClientOperation clientOperation) { }

        public void ApplyDispatchBehavior(OperationDescription operationDescription, DispatchOperation dispatchOperation)
        {
            var serializerBehavior = operationDescription.Behaviors.Find<DataContractSerializerOperationBehavior>();

            if (dispatchOperation.Formatter == null)
            {
                ((IOperationBehavior)serializerBehavior).ApplyDispatchBehavior(operationDescription, dispatchOperation);
            }

            IDispatchMessageFormatter innerDispatchFormatter = dispatchOperation.Formatter;

            dispatchOperation.Formatter = new MyCustomMessageFormatter(innerDispatchFormatter);
        }

        public void Validate(OperationDescription operationDescription) { }
    }

我们将刚刚定义的行为添加到方法中

 [AttributeUsage(AttributeTargets.Method)]
    public class MyMessageAttribute : Attribute, IOperationBehavior
    {
        public void AddBindingParameters(OperationDescription operationDescription, BindingParameterCollection bindingParameters) { }

        public void ApplyClientBehavior(OperationDescription operationDescription, ClientOperation clientOperation) { }

        public void ApplyDispatchBehavior(OperationDescription operationDescription, DispatchOperation dispatchOperation)
        {
            var serializerBehavior = operationDescription.Behaviors.Find<DataContractSerializerOperationBehavior>();

            if (dispatchOperation.Formatter == null)
            {
                ((IOperationBehavior)serializerBehavior).ApplyDispatchBehavior(operationDescription, dispatchOperation);
            }

            IDispatchMessageFormatter innerDispatchFormatter = dispatchOperation.Formatter;

            dispatchOperation.Formatter = new MyCustomMessageFormatter(innerDispatchFormatter);
        }

        public void Validate(OperationDescription operationDescription) { }
    }

        [MyMessage]
        public Result GetUserData(string name)
        {....
