请帮助我，我想使用 C# 生成根 XML 以发送到服务器。
对于类似的
<?xml version="1.0" encoding="utf-8"?>
<GovTalkMessage xmlns="http://www.govtalk.gov.uk/CM/envelope">
<EnvelopeVersion>2.0</EnvelopeVersion>
<Header>
<MessageDetails>
<Class>SendDocument</Class>
<Qualifier>request</Qualifier>
<Function>submit</Function>
<TransactionID>5</TransactionID>
<CorrelationID></CorrelationID>
</MessageDetails>
<SenderDetails>
<IDAuthentication>
<SenderID>[USER]</SenderID>
<Authentication>
<Method>clear</Method>
<Value>[PASS]</Value>
</Authentication>
</IDAuthentication>
</SenderDetails>
</Header>
<Body>
<Message xmlns="urn:g3.ge:dea:call:SendDocument:v1">
................
</Message>
</Body>
</GovTalkMessage>
事先感谢您的回答
首先，您需要为 XML 生成 XSD 架构。政府网关应为您的特定提交域提供 XSD。如果没有，则可以使用 XML 菜单中"创建架构"下的 Visual Studio XML 工具从 XML 文件生成一个相当好的架构。
获得架构文件后，可以使用 Windows SDK 中的 XSD.exe 工具来生成服务类。如果您有多个架构文件(例如，一个用于 GovTalkMessage 包装器，一个用于特定域，如下面示例中的税务局(，您可以将它们组合到一个服务类文件中：
如果 XSD 工具安装在其典型位置，则可以运行以下命令：
C:Program Files (x86)Microsoft SDKsWindowsv7.0ABinx64>xsd.exe /c c:SchemasGovTalkMessage.xsd C:ServiceClassesIREnvelope.xsd /o:C:GovTalkApplication
一旦有了 XML 的服务类，您就可以从数据创建新对象并相当容易地将它们序列化为 XML。在此代码示例中，我使用配置文件中的 AppSettings 来存储各种常量值，并使用名为 _localData 的私有 DataTable 来保存我放入 IR R68 有效负载(在元素中(的身体数据。我也在这里使用log4net记录器，这是偶然的。CreateIRBody 方法是您必须为需要包含的任何有效负载编写的东西：
public GovTalkMessage CreateRequestMessage(string env)
{
try
{
log.Debug("CreateRequestMessage called");
GovTalkMessageBody Body = new GovTalkMessageBody();
IR68 ir68 = new IR68(_localData);
log.Debug("Creating IR68 body ...");
IRenvelope ire = new IRenvelope();
ire = ir68.CreateIRBody();
//serialize ire into XmlElement and then set Body.Any =
XmlElement xe = GiftAidSubmissionProcessController.SerializeIREnvelope(ire);
XmlElement[] XmlElementIRenvelope = new XmlElement[1];
XmlElementIRenvelope[0] = xe;
Body.Any = XmlElementIRenvelope;
//GovTalkDetails
GovTalkMessageGovTalkDetailsChannelRoutingChannel Channel = new GovTalkMessageGovTalkDetailsChannelRoutingChannel();
Channel.Version = ConfigurationManager.AppSettings["ChannelVersion"];
Channel.Product = ConfigurationManager.AppSettings["ChannelProduct"];
Channel.ItemElementName = ItemChoiceType.URI;
Channel.Item = ConfigurationManager.AppSettings["ChannelURI"];
GovTalkMessageGovTalkDetailsChannelRouting ChannelRouting = new GovTalkMessageGovTalkDetailsChannelRouting();
ChannelRouting.Channel = Channel;
GovTalkMessageGovTalkDetailsKey Key = new GovTalkMessageGovTalkDetailsKey();
Key.Type = ConfigurationManager.AppSettings["GovTalkDetailsKeyType"];
Key.Value = ConfigurationManager.AppSettings["GovTalkDetailsKey"];
GovTalkMessageGovTalkDetails Details = new GovTalkMessageGovTalkDetails();
GovTalkMessageGovTalkDetailsChannelRouting[] ChannelRoutings =
new GovTalkMessageGovTalkDetailsChannelRouting[1];
ChannelRoutings[0] = ChannelRouting;
Details.ChannelRouting = ChannelRoutings;
GovTalkMessageGovTalkDetailsKey[] Keys = new GovTalkMessageGovTalkDetailsKey[1];
Keys[0] = Key;
Details.Keys = Keys;
string[] TargetDetails = new string[1];
TargetDetails[0] = ConfigurationManager.AppSettings["GovTalkDetailsTargetOrganistion"];
Details.TargetDetails = TargetDetails;
//GovTalk Header
GovTalkMessageHeaderSenderDetailsIDAuthenticationAuthentication Authentication = new GovTalkMessageHeaderSenderDetailsIDAuthenticationAuthentication();
switch (ConfigurationManager.AppSettings["SenderAuthenticationMethod"])
{
case "MD5":
Authentication.Method = GovTalkMessageHeaderSenderDetailsIDAuthenticationAuthenticationMethod.MD5;
break;
case "clear":
Authentication.Method = GovTalkMessageHeaderSenderDetailsIDAuthenticationAuthenticationMethod.clear;
break;
case "W3Csigned":
Authentication.Method = GovTalkMessageHeaderSenderDetailsIDAuthenticationAuthenticationMethod.W3Csigned;
break;
}
Authentication.Role = ConfigurationManager.AppSettings["SenderAuthenticationRole"];
Authentication.Item = ConfigurationManager.AppSettings["SenderAuthenticationValue"];
GovTalkMessageHeaderSenderDetailsIDAuthentication IDAuthentication = new GovTalkMessageHeaderSenderDetailsIDAuthentication();
IDAuthentication.SenderID = ConfigurationManager.AppSettings["SenderID"];
GovTalkMessageHeaderSenderDetailsIDAuthenticationAuthentication[] Authentications = new GovTalkMessageHeaderSenderDetailsIDAuthenticationAuthentication[1];
Authentications[0] = Authentication;
IDAuthentication.Authentication = Authentications;
GovTalkMessageHeaderSenderDetails SenderDetails = new GovTalkMessageHeaderSenderDetails();
SenderDetails.IDAuthentication = IDAuthentication;
GovTalkMessageHeaderMessageDetails MessageDetails = new GovTalkMessageHeaderMessageDetails();
MessageDetails.Class = ConfigurationManager.AppSettings["MessageDetailsClass"];
MessageDetails.Qualifier = GovTalkMessageHeaderMessageDetailsQualifier.request;
MessageDetails.FunctionSpecified = true;
MessageDetails.Function = GovTalkMessageHeaderMessageDetailsFunction.submit;
MessageDetails.TransformationSpecified = true;
MessageDetails.Transformation = GovTalkMessageHeaderMessageDetailsTransformation.XML;
MessageDetails.GatewayTest = ConfigurationManager.AppSettings["MessageDetailsGatewayTest"];
if (env == "local")
{
MessageDetails.GatewayTimestampSpecified = true;
MessageDetails.GatewayTimestamp = DateTime.Now;
}
else
{
MessageDetails.GatewayTimestampSpecified = false;
MessageDetails.GatewayTimestamp = DateTime.MinValue; }
GovTalkMessageHeader Header = new GovTalkMessageHeader();
Header.MessageDetails = MessageDetails;
Header.SenderDetails = SenderDetails;
GovTalkMessage GovTalkMessage = new hmrcclasses.GovTalkMessage();
GovTalkMessage.EnvelopeVersion = ConfigurationManager.AppSettings["GovTalkMessageEnvelopeVersion"];
GovTalkMessage.Header = Header;
GovTalkMessage.GovTalkDetails = Details;
GovTalkMessage.Body = Body;
log.Info("GovTalkMessage created successfully");
return GovTalkMessage;
}
catch (Exception ex)
{
log.Error(ex);
throw;
}
}
希望这可以帮助您入门。
- 复制整个 XML (CRTL+A CTRL+C(
- 打开 Visual Studio 并创建新类
- 单击菜单 - 编辑 -> 选择性粘贴 -> 将 XML 粘贴为类
之后，您可以使用 XmlSerializer 生成该 XML
var entity = new GovTalkMessage();
//fill entity properties with data
var writer = new StringWriter();
var serializer = new XmlSerializer(typeof(GovTalkMessage));
serializer.Serialize(writer, entity);
var xmlText = writer.ToString();
//and so on...
这是一个完整的XML文件。
