Hello,
When i test simple LinqToXml exemple with olive module, i have an error.
I would know if an error is in my code.
---- 8< --- code --- 8< ----
using System;
using System.Linq;
using System.Xml.Linq;
using System.Collections.Generic;
class Linquou
{
public static void Main(string[] args)
{
XElement root = XElement.Load(@"utilisateur.xml");
if(root.Element("utilisateurs") != null) {
var listUser = from u in
root.Element("utilisateurs").Elements("utilisateur")
select
new { Nom = u.Element("nom").Value,
Prenom =
u.Element("prenom").Value
};
foreach(var u in listUser) {
System.Console.WriteLine("An user: {0} {1}", u.Prenom, u.Nom);
}
}
}
}
---- 8< --- end code --- 8< ----
I compile this code with :
gmcs -r:System.Core.dll -r:lib/System.Xml.Linq -langversion:linq sampleLinq.cs
Compilation return 0 error but when i run sampleLinq.exe i have this
error :
[mono] ~/Codaz/Cs/linqt @ make
gmcs -r:System.Core.dll -langversion:linq -r:lib/System.Xml.Linq
exemple2.cs -out:exemple2.exe
