I have to readout an XML-file (with already existing content) from my local Visual Studio 2013 project structure, but not from harddrive-directory (as mentioned in the most tutorials/ guides, I've read in the last 2 hours...). After the readout process, I have to search for some tag-names in it.
I have to do this way, because the requirement is, that the specified local XML-file shouldn't appear after the build process in output directory...
So how can I do that?
==================================================================================
This is my AccessData.xml-file (In Project-directory: "LinqToXML_Example/AccessData.xml"):
<?xml version="1.0" encoding="utf-8"?>
<Clients>
<Client>
<Username>Administrator</Username>
<Password>Admin-Password</Password>
<Settings>
<Item1>Admin-Setting 1</Item1>
<Item2>Admin-Setting 2</Item2>
<Item3>Admin-Setting 3</Item3>
</Settings>
</Client>
<Client>
<Username>Service</Username>
<Password>Srv-Password</Password>
<Settings>
<Item1>Srv-Setting 1</Item1>
<Item2>Srv-Setting 2</Item2>
<Item3>Srv-Setting 3</Item3>
</Settings>
</Client>
<Client>
<Username>Customer</Username>
<Password>Cust-Password</Password>
<Settings>
<Item1>Cust-Setting 1</Item1>
<Item2>Cust-Setting 2</Item2>
<Item3>Cust-Setting 3</Item3>
</Settings>
</Client>
</Clients>
This is my Program.cs-file:
using System;

using System.Linq;

using System.Xml.Linq;
using System.Reflection;
namespace LinqToXML_Example
{
public class Program

{
var userName = from p in clients.Elements()
where p.Element("Username").Value == username
select p.Element("Username").Value;

{

}

}
return "Cannot get the username's password, because of a wrong Username!";
}
public static List<string> ReadUserSettings(string username, XElement clients)
{
List<string> settingsList = new List<string>();
if (IsUsernameExisting(username, clients))
{
var setting = from s in clients.Elements()
where s.Element("Username").Value == username
select s.Element("Settings");
foreach (var p in setting)
{
settingsList.Add(p.Element("Item1").Value);
settingsList.Add(p.Element("Item2").Value);
settingsList.Add(p.Element("Item3").Value);
}
return settingsList;
}
var errorMsg = "Cannot get the username's settings, because of a wrong Username!";
settingsList.Add(errorMsg);
return settingsList;
}
public static void Query(string username, XElement clients)
{
// Search for specific Username:
Console.WriteLine("Search for Client " + "'" + username + "' (based on Usernames):");
string result = SearchForUsername(username, clients);
Console.WriteLine(result);
Console.WriteLine("");
// Search for Password of Client:
Console.WriteLine("Search for Password of Client " + "'" + username + "':");
result = SearchForUsernamePassword(username, clients);
Console.WriteLine(result);
Console.WriteLine("");
// Readout the Settings of Client:
Console.WriteLine("Readout the Settings of Client " + "'" + username + "':");
List<string> resultList = new List<string>();
resultList = ReadUserSettings(username, clients);
if (resultList.Count != 1)
{
for (int i = 0; i < resultList.Count(); i++)
{
var itemcounter = i + 1;
Console.WriteLine("Item" + itemcounter + ": " + resultList.ElementAt(i));
}
}
else Console.WriteLine(resultList.ElementAt(0));
Console.Read();
}
static void Main()
{
var asm = Assembly.GetExecutingAssembly();
// Bug fix: "AccessData.xml" has to be changed to: "LinqToXML_Example.AccessData.xml"
var textStream = asm.GetManifestResourceStream("AccessData.xml");
// Bug fix: Has to be changed to: var xmlReader = new XmlTextReader(textStream);
var xmlReader = new XmlReader(textStream);
XElement clients = XElement.Load(xmlReader);
Query("Administrator", clients);
}
}
}
I've changed the properties of AccessData.xml file to:
Build Action = "Resource" // Bug fix: Has to be changed to: 'Embeded Resource'
Copy to output directory = "Never"
Unfortunately I have no access to my xml-file :((
