我正在创建XML来发送数据。数据包含多种数据类型，如字符串，整数和小数。我的XML格式和c＃代码创建如下。
<root>
<data>
<struct>
<PartnerCD></PartnerCD>
<UserName> </UserName>
<Password> </Password>
<Action> </Action>
<OfficeCD></OfficeCD>
<ChannelCD></ChannelCD>
<Token></Token>
<Notes> </Notes>
<Products>
<Product>
<ProductID></ProductID>
<SVA></SVA>
<Amount></Amount>
</Product>
</Products>
</struct>
</data>
</root>
我的c＃代码是
public static string CreateRequestXML(string partnerCd, string userName, string password, string action, string productId, string token, string sva, string amount)
{
XmlDocument doc = new XmlDocument();
XmlElement elemRoot = doc.CreateElement("root");
XmlElement elemData = doc.CreateElement("data");
XmlElement elemStruct = doc.CreateElement("struct");
XmlElement elemProducts = doc.CreateElement("Products");
XmlElement elemProduct = doc.CreateElement("Product");
doc.AppendChild(elemRoot);
elemRoot.AppendChild(elemData);
elemData.AppendChild(elemStruct);
//Insert data here
InsertDataNode(doc, elemStruct, "PartnerCD", partnerCd);
InsertDataNode(doc, elemStruct, "UserName", userName);
InsertDataNode(doc, elemStruct, "Password", password);
InsertDataNode(doc, elemStruct, "Action", action);
InsertDataNode(doc, elemStruct, "Token", token);
elemStruct.AppendChild(elemProducts);
elemProducts.AppendChild(elemProduct);
InsertDataNode(doc, elemProduct, "ProductID", productId);
InsertDataNode(doc, elemProduct, "SVA", sva);
InsertDataNode(doc, elemProduct, "Amount", amount);
return doc.OuterXml;
}
private static void InsertDataNode(XmlDocument doc, XmlElement parentElem, string nodeName, string nodeValue)
{
XmlElement elem = doc.CreateElement(nodeName);
elem.InnerText = nodeValue;
parentElem.AppendChild(elem);
}
我的结果是
<root>
<data>
<struct>
<PartnerCD>123</PartnerCD>
<UserName>api</UserName>
<Password>pass</Password>
<Action>token</Action>
<Token>4847898</Token>
<Products>
<Product>
<ProductID>123</ProductID>
<SVA>e8a8227c-bba3-4f32-a2cd-15e8f246344b</SVA>
<Amount>700</Amount>
</Product>
</Products>
</struct>
</data>
</root>
我希望PartnerCD和ProductId元素为整数，Amount元素为decimal。我尝试过XMLNodeType但没有用。
答案 0 :(得分：1)
Xml没有＆＃34;数据类型的概念＆＃34;本地，您引用的XmlNodeType是什么类型的 Node （例如元素，属性等），而不是其中包含的数据类型。
答案 1 :(得分：1)
数据类型在XML中是无关紧要的，它都是在它使用的模式中定义的，这是存储预期数据类型声明的地方。
因此，如果您的XSD表明/root/data/struct/PartnerCD的类型为xs:int，则验证文件时会出现验证错误。 XML本身只是所有数据的容器，它不包含元信息。您可以手动定义它，但Point在大约99.99％的情况下超出了我的范围，而且它或多或少是XML的混蛋，比如MSXML，它将了解您的目标。

就个人而言，我会创建一个对象并将序列化\反序列化为\来自XML，如此......
