Merge multiple xml files in one file

Hi friend,

I tried this but I am getting an error (Error: 'XDocument' does not contain a definition for 'Dump' and no extension method 'Dump' accepting a first argument of type 'XDocument'could be found ) on masterfile.Dump();

Can anyone help regarding this error ???

MY CODE:-

protected void Button3Merge_Click(object sender, EventArgs e)
{
var downloadfolder = @"E:\Desktop\XeroConnectData\Schema\All_22files\"; // download folder path
string[] files = Directory.GetFiles(downloadfolder);
var masterfile = new XDocument();
XElement newDocument = new XElement("Invoice");
masterfile.Add(newDocument);
foreach (var file in files)
{
Console.WriteLine("--------------------------------------------------");
Console.WriteLine(file);
Console.WriteLine("--------------------------------------------------");
XDocument xdoc = XDocument.Load(file);
masterfile.Root.Add(xdoc.Descendants("Invoice")); // root note
}
masterfile.Dump();
masterfile.Save(@"E:\Desktop\XeroConnectData\merged_.xml");
}

Hello Amit refer below sample code, this might help you
OpenFileDialog ofd = new OpenFileDialog();
ofd.Multiselect = true;
ofd.Filter = "XML files (*.xml) |*.xml";
bool? result = ofd.ShowDialog();
if(result == true)
{
    DataSet dsAll = new DataSet();
    foreach (string fileName in ofd.FileNames)
    {
        DataSet dsTemp = new DataSet();
        dsTemp.ReadXml(fileName);
        dsAll.Merge(dsTemp);
    }
    string directoryName = Path.GetDirectoryName(ofd.FileNames.First());
    string exportfileName = Path.Combine(directoryName, "marged.xml");
    dsAll.WriteXml(exportfileName);
}
