C# .NET和SOAP标记问题（将对象序列化为XML）

快速提问：我正在创建一个XML souap信封，该信封应具有以下结构：

    <?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <GetSomething>
      <SecurityToken>{{SecurityToken}}</SecurityToken>
      <ID>{{ID}}</ID>
      <StartDate>{{StartDate}}</StartDate>
      <EndDate>{{EndDate}}</EndDate>
    </GetSomething>
  </soap:Body>
</soap:Envelope>

有人知道如何将这些soap:tag生成到我生成的XML中吗？我知道我可以将它们硬编码为字符串并添加参数（ID、令牌和日期），但我认为从类生成XML更干净。提前谢谢

有人知道如何将这些soap:tags生成到我生成的 XML

那些

soap:

标记（如您所称）被称为

名称空间

。您可以创建一个名称空间，然后在此名称空间下包含

信封

和

正文

Soap有一个默认名称空间

http://schemas.xmlsoap.org/soap/envelope/

您可以在.NET中使用

XmlDocument

或

XDocument

。在下面的示例中，我使用了

XDocument

，这是我最喜欢的XML类

//Declare Soap Namespace
XNamespace ns = @"http://schemas.xmlsoap.org/soap/envelope/";

//Create Soap Envelope
var doc = new XDocument(
    new XDeclaration("1.0", "utf-8", null),
    new XElement(ns + "Envelope",
        new XAttribute(XNamespace.Xmlns + "xsi", @"http://www.w3.org/2001/XMLSchema-instance"),
        new XAttribute(XNamespace.Xmlns + "xsd", @"http://www.w3.org/2001/XMLSchema"),
        new XAttribute(XNamespace.Xmlns + "soap", ns),

        new XElement(ns + "Body", 
            new XElement(ns + "GetSomething",
                new XElement("SecurityToken", "{{SecurityToken}}"),
                new XElement("ID", "{{ID}}"),
                new XElement("StartDate", "{{StartDate}}"),
                new XElement("EndDate", "{{EndDate}}")
                )//<GetSomething>
            ) //<soap:Body>
        )//<soap:Envelope>
    );

//声明Soap命名空间
XNS=@”http://schemas.xmlsoap.org/soap/envelope/";
//创建Soap信封
var doc=新XDocument(
新XDeclaration（“1.0”，“utf-8”，空），
新元素（ns+“信封”，
新的XAttribute（XNamespace.Xmlns+“xsi”，@”http://www.w3.org/2001/XMLSchema-instance"),
新的XAttribute（XNamespace.Xmlns+“xsd”，@”http://www.w3.org/2001/XMLSchema"),
新的XAttribute（XNamespace.Xmlns+“soap”，ns），
新元素（ns+“主体”，
新XElement（ns+“获取某物”，
新的XElement（“SecurityToken”，“{{SecurityToken}}”），
新的XElement（“ID”，“{{ID}”），
新的XElement（“StartDate”，“{{StartDate}”），
新的XElement（“EndDate”，“{{EndDate}}”）
)//
) //
)//
);

当您在

XElement

中组合名称空间时，它将向

XElement

名称（标记名）添加前缀。例如

ns+“信封”

它将输出

，这意味着

元素位于

soap

命名空间下
