Merge multiple xml files in one file

Question

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");
}
