C# 动态类型 模型转XML
<?xml version="1.0" encoding="utf-8"?> <qrylist><order orderid="1234567890"></order> <order orderid="1234567891"></order> <order orderid="1234567892"></order> </qrylist>
模型定义
public class RequestXML
{
public qrylistModel qrylist { get; set; }
public class qrylistModel
{
public ordeModel order { get; set; }
public class ordeModel
{
public string orderid { get; set; }
}
}
}
使用方法：
RequestXML requestXML = new RequestXML();
requestXML.qrylist = new RequestXML.qrylistModel();
requestXML.qrylist.order = new RequestXML.qrylistModel.ordeModel();
requestXML.qrylist.order.orderid = "123123123";
StringBuilder strbuil = new StringBuilder();
var xmlstr = XMLHelper.ModelRecurveToXML(requestXML, strbuil);
xmlstr = strbuil.Insert(0, xmlstr).ToString();
XmlDocument docReqContex = new XmlDocument();
XmlDeclaration decl = docReqContex.CreateXmlDeclaration("1.0", "utf-8", null);
docReqContex.LoadXml(xmlstr);
docReqContex.InsertBefore(decl, docReqContex.DocumentElement);
忘记看他这个xml 格式是个List 更新一下使用方法
RequestXML requestXML = new RequestXML();
requestXML.qrylist = new RequestXML.qrylistModel();
requestXML.qrylist.order = new List<RequestXML.qrylistModel.ordeModel>();
requestXML.qrylist.order.Add(new RequestXML.qrylistModel.ordeModel()
{
orderid="123123"
});
requestXML.qrylist.order.Add(new RequestXML.qrylistModel.ordeModel()
{
orderid = "44433333"
});
StringBuilder strbuil = new StringBuilder();
var xmlstr = XMLHelper.ModelRecurveToXML(requestXML, strbuil);
xmlstr = strbuil.Insert(0, xmlstr).ToString();
XmlDocument docReqContex = new XmlDocument();
XmlDeclaration decl = docReqContex.CreateXmlDeclaration("1.0", "utf-8", null);
docReqContex.LoadXml(xmlstr);
docReqContex.InsertBefore(decl, docReqContex.DocumentElement);
