Ich frage mich, wie diese Linq-Abfrage, die ich in eine Dropdown-Liste in einer C# -Webanwendung geschrieben habe, zu binden. Es ruft eine XML-Datei auf. Ich werde etwas von der XML-Datei posten, aber die 2K-Zeilen wert, also werde ich nur ein Snippet posten.LINQ-Abfrage an Dropdown-Liste binden C#
public void ddlBinding()
{
// Getting the XML file imported in
string filePath = @"C:\Projects\MEAS\Central\MillView\PVDA\Main\PVDA\PVDA.Web\MillData.xml";
// Set the file path
XDocument xDoc = XDocument.Load(filePath);
// Setting a variable to dump the data into the dropdownlist
var dropDownDataList = GetMachineInfo(xDoc, 2);
}
// LINQ Queries for binding
public List<Machine> GetMachineInfo(XDocument xDoc, int machineNumber)
{
// Get the elements under a specific machine and create
// a list of Machine objects
// Different Linq queries to get the machine data entered
// This needs to be incorporated for the mill also, this does not get the mill name
return xDoc.XPathSelectElements("./mmsdata/mill/mach")
.Where(x => x.Attribute("n").Value == machineNumber.ToString())
.Elements()
.Select(x => new Machine
{
sensName = x.Value,
snsrN = Convert.ToInt32(x.Attribute("n").Value),
calctype = x.Attribute("calctype").Value
}).ToList();
}
public class Machine
{
// Getting all the objects to the machine
public int snsrN { get; set; }
public string calctype { get; set; }
public string sensName { get; set; }

Mögliche Duplikat [Bindungs LINQ-Abfragen und XML Dropdownlists] (http://stackoverflow.com/questions/37484547/binding-linq-queries-and-xml-to-dropdownlists) –
Dies ist dieselbe Frage wie die, die du vor 4 Tagen gestellt hast (http://stackoverflow.com/questions/37484547/binding-linq-queries-and-xml-to-dropdownlists) (und die Frage, die du heute Morgen gestellt hast, dass du ' ve seit gelöscht). Warum macht man das nicht besser? –
