如何使用 XMLDocument 或 XMLWriter 生成它
将数据加载到 DataSet 并使用 Write XML。这是您可以尝试的最简单的方法
DataSet oDsData = new DataSet();
oDsData.WriteXml("path", XmlWriteMode.WriteSchema);
如果您的数据位于 MSSQL 服务器中，这可能是解决方案之一。我假设您的数据驻留在数据库中的 table (##tmp_test) 中。
public string GetXML()
{
XmlDocument document = new XmlDocument();
XmlDeclaration xmlDeclaration = document.CreateXmlDeclaration("1.0", "UTF-8", null);
XmlElement root = document.DocumentElement;
document.InsertBefore(xmlDeclaration, root);
var returnElement = document.CreateElement( "return");
returnElement.SetAttribute("xmlns:rmas", "value here");
returnElement.SetAttribute("xmlns:xsi", "value here");
returnElement.SetAttribute("noNamespaceSchemaLocation", "value here");
var header = document.CreateElement("header");
var rc = document.CreateElement("return-code");
rc.InnerText = "\"\"";
header.AppendChild(rc);
var rd = document.CreateElement("return-desc");
rd.InnerText = "\"\"";
header.AppendChild(rd);
var aad = document.CreateElement("as-at-date");
aad.InnerText = "\"\"";
header.AppendChild(aad);
var oc = document.CreateElement("operator-code");
oc.InnerText = "\"\"";
header.AppendChild(oc);
returnElement.AppendChild(header);
var body = document.CreateElement("body");
body.InnerXml = GetBodyXML();
returnElement.AppendChild(body);
document.AppendChild(returnElement);
return document.OuterXml;
}
