Question

C＃全新。我正在开发一个ASP MVC应用程序。我将数据导出到XML，所有这些都正常工作。我遇到的问题是我无法弄清楚如何正确输出数据。基本上我是根据ID以及登录用户ID从列中获取数据，例如12。这个例子根据controllerID和userID拉出3行，数字如下：12,12,11。在我的XML中我希望它显示1 - 35.他们现在的方式是1-12 ，1-12,1-11。数据是正确的，但是我可以从列表中返回的数字，将它们全部加在一起并显示为1-35。这是代码：

public ActionResult ExportToXML()
{
    var lClist = db.LightControllers.Where(x => x.userID == LoggedInUser.id).OrderBy(x => x.controllerID).ToList();
    Networks n = new Networks();
    n.computer = "computer1";
    foreach(var i in lClist)
    {

        int numU = Convert.ToInt32(i.NumUniverses);
        for (int j = 0; j < numU; j++)

        {
            network netToAdd = new network();
            netToAdd.NetworkType = "E131";
            netToAdd.ComPort = i.ipaddress;
            netToAdd.BaudRate = (j + 1).ToString();
            netToAdd.MaxChannels = "510";

            n.network.Add(netToAdd);
        }
    }

    XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
    ns.Add("", "");
    string path = Server.MapPath("~/XMLFiles/");
    string filename = "x_networks.xml";
    string filepath = Path.Combine(path, filename);
    if (System.IO.File.Exists(filepath))
    {
        System.IO.File.Delete(filepath);
    }
    XmlSerializer serial = new XmlSerializer(typeof(viewmodels.Networks));
    StreamWriter writer = new StreamWriter(filepath);
    serial.Serialize(writer, n, ns);
    writer.Close();

    return File(filepath, "application/xml", filename);
}

以下是当前xml输出的示例。

<?xml version="1.0" encoding="utf-8"?>
<Networks computer="xlights">
    <network NetworkType="E131" ComPort="192.168.1.110" BaudRate="1" MaxChannels="510" />
    <network NetworkType="E131" ComPort="192.168.1.110" BaudRate="2" MaxChannels="510" />
    ...
</Networks>

试试这个：

public ActionResult ExportToXML()
{
    var lClist = db.LightControllers.Where(x => x.userID == LoggedInUser.id).OrderBy(x => x.controllerID).ToList();

    int baudIterator = 1;

    Networks n = new Networks();
    n.computer = "computer1";
    foreach(var i in lClist)
    {

        int numU = Convert.ToInt32(i.NumUniverses);
        for (int j = 0; j < numU; j++)

        {
            network netToAdd = new network();
            netToAdd.NetworkType = "E131";
            netToAdd.ComPort = i.ipaddress;
            netToAdd.BaudRate = baudIterator.ToString();
            netToAdd.MaxChannels = "510";

            n.network.Add(netToAdd);
            baudIterator++;
        }
    }

    XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
    ns.Add("", "");
    string path = Server.MapPath("~/XMLFiles/");
    string filename = "x_networks.xml";
    string filepath = Path.Combine(path, filename);
    if (System.IO.File.Exists(filepath))
    {
        System.IO.File.Delete(filepath);
    }
    XmlSerializer serial = new XmlSerializer(typeof(viewmodels.Networks));
    StreamWriter writer = new StreamWriter(filepath);
    serial.Serialize(writer, n, ns);
    writer.Close();

    return File(filepath, "application/xml", filename);
}

导出有效，但未正确显示数据
