我正面临使用XDocument写入xml文件的问题，而XElement这里的输出文件是错误的，应该如何。 这是最终的xml文件的样子，但它不符合要求。
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<CMS>
<Device Name="CM_HOST" Type="TR">
<PortA Connected_BY="Directly">
<Device TB="AR" ParentConnectedToPort="A" Name="Akitio" Cable="20G Passive" />
</PortA>
<PortA Connected_BY="Directly">
<Device TB="AR" ParentConnectedToPort="A" Name=" doc1" Cable="20G Passive" />
</PortA>
</Device>
</CMS>
它应该是这样的：
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<CMS>
<Device Name="CM_HOST" Type="TR">
<PortA Connected_BY="Directly">
<Device TB="AR" ParentConnectedToPort="A" Name="Akitio" Cable="20G Passive" >
<PortA>
<Device TB="AR" ParentConnectedToPort="A" Name=" doc1" Cable="20G Passive" />
</PortA>
</Device>
</PortA>
</Device>
</CMS>
这里是我试图运行此代码的代码本身：
private void exportToXmlFile(List<Device> list)
{
XDocument xdoc = new XDocument(
new XDeclaration("1.0", "utf-8", "yes"));
XElement elm = new XElement("CMS");
XElement hostDev = new XElement("Device");
hostDev.Add(new XAttribute("Name", list.ElementAt(0).Name));
hostDev.Add(new XAttribute("Type", list.ElementAt(0).TBType1));
foreach (Device device in deviceToAddList)
{
if (device.Name != "CM_HOST")
{
if(device.DeviceConnectedTo=="A")
{
if (device.ConnectedBy == "Directly")
{
XElement deviceElem = new XElement("Device");
XElement portAelem = new XElement("PortA");
portAelem.Add(new XAttribute("Connected_BY", device.ConnectedBy));
deviceElem.Add(new XAttribute("TB", device.TBType1));
deviceElem.Add(new XAttribute("ParentConnectedToPort", device.ParentConnectedTo));
deviceElem.Add(new XAttribute("Name", device.Name));
deviceElem.Add(new XAttribute("Cable", device.Cable));
portAelem.Add(deviceElem);
hostDev.Add(portAelem);
}
}
}
}
elm.Add(hostDev);
xdoc.Add(elm);
xdoc.Save(Application.StartupPath + "\\Topology.xml");
}
这是包含所有属性的Device类：
public class Device
{
string name;
string TBType;
string connectedBy;
string parentConnectedTo;
string ftdiPort;
string cable;
string parentName;
string deviceConnectedTo;
decimal plusPin;
decimal MinusPin;
int xmlevel;
public Device()
{
this.Name = "CM_HOST";
this.ParentName = "None";
this.TBType1 = "TR";
this.parentConnectedTo = "PCI";
this.Xmlevel = 0;
this.deviceConnectedTo = "None";
}
public string Name { get => name; set => name = value; }
public string TBType1 { get => TBType; set => TBType = value; }
public string ConnectedBy { get => connectedBy; set => connectedBy = value; }
public string ParentConnectedTo { get => parentConnectedTo; set => parentConnectedTo = value; }
public string FtdiPort { get => ftdiPort; set => ftdiPort = value; }
public string Cable { get => cable; set => cable = value; }
public string ParentName { get => parentName; set => parentName = value; }
public string DeviceConnectedTo { get => deviceConnectedTo; set => deviceConnectedTo = value; }
public decimal PlusPin { get => plusPin; set => plusPin = value; }
public decimal MinusPin1 { get => MinusPin; set => MinusPin = value; }
public int Xmlevel { get => xmlevel; set => xmlevel = value; }
}
需要连接以下元素，不要添加为新行（： 谢谢所有人......
这就是我期望的最终输出的原因：
<?xml version="1.0" encoding="UTF-8"?>
<CMS>
<Device TB="CM_HOST" properties="{'Name':'Host', 'Type' : 'TR' }" >
<PortA Connected_BY= "MiniBot">
<Device TB="TR" ParentConnectedToPort ='PortB' properties="{'Pins': {'MiniBot_minus_pin': 2, 'MiniBot_pluse_pin': 3}, 'Type': 'TR' , 'FTDI_Port':0 ,'Name':'SV_Board','Cable': '20G Passive' }" >
<PortB Connected_BY= "MiniBot">
<Device TB="AR" ParentConnectedToPort ='PortB' properties="{'Pins': {'MiniBot_minus_pin': 0, 'MiniBot_pluse_pin': 1},'Type': 'AR' , 'FTDI_Port':0 ,'Name':'StarTechDoc','Cable': '20G Passive' }">
<PortA Connected_BY= "Directly">
<Device TB="None" properties="{'Type': 'None' , 'FTDI_Port':0 ,'Name':'samsung-USB3','Cable': '20G Passive'}" ></Device>
</PortA>
<PortB Connected_BY= "ParentConnected"></PortB>
<PortE><Device TB="None" properties="{'Type': 'None' , 'FTDI_Port':0 ,'Name':'samsung-USB3','Cable': '20G Passive'}" ></Device></PortE>
</Device>
</PortB>
<PortA Connected_BY= "ParentConnected"></PortA>
<PortE Connected_BY= "None"></PortE>
</Device>
</PortA>
<PortB Connected_BY= "None"></PortB>
</Device>
</CMS>

无需查看代码，您可以在XML文件中手动编写元素和属性。为什么不使用XML序列化？只需创建具有正确结构的类，但在类中的列表中创建元素的子元素。以这种方式构建所需的结构很容易，然后像这样序列化XML：
XmlSerializer xmlSerializer = new XmlSerializer(typeof(*NameOfYourClass*));
using (StringWriter writer = new StringWriter())
{
using (XmlTextWriter xmlWriter = new XmlTextWriter(writer))
{
xmlWriter.Formatting = Formatting.Indented;
xmlWriter.Indentation = 4;
xmlSerializer.Serialize(xmlWriter, *InstanceOfYourClass*);
return writer.ToString());
}
}
为什么你的XML必须如下所示：
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<CMS>
<Device Name="CM_HOST" Type="TR">
<PortA Connected_BY="Directly">
<Device TB="AR" ParentConnectedToPort="A" Name="Akitio" Cable="20G Passive" >
<PortA>
<Device TB="AR" ParentConnectedToPort="A" Name=" doc1" Cable="20G Passive" />
</PortA>
</Device>
</PortA>
</Device>
</CMS>
而不喜欢这个？
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<CMS>
<Device Name="CM_HOST" Type="TR">
<PortA Connected_BY="Directly">
<Device TB="AR" ParentConnectedToPort="A" Name="Akitio" Cable="20G Passive" >
<Device TB="AR" ParentConnectedToPort="A" Name=" doc1" Cable="20G Passive" />
</PortA>
</Device>
</CMS>
