(adsbygoogle = window.adsbygoogle || []).push({}); Well I thought this might help some people, basically this can be used for a variety of things, but today I'm going to use an xml document with login details, beware though, this is defiantly not safe for a login system since anybody can access the file :p. First we want to start a new c# project in visual studios, then we want to add these to the top of the programs code-

    

Using System.Net;

Using System.IO;

Using System.Xml;

Using System.Xml.Linq;

Then after "public form1() { }" we want to add this-

    

XmlDocument Xml = new XmlDocument()

So now we have a new xml document, we can start using it. I'm going to load the xml on a button click, but you can also do it on the form load if you want it to refresh every time it's opened.

So I'm going to add a button to my form (in the designer) and double click it and add this-

     

Xml.Load(https://www.yourwebsite.com/yourxmlfile.xml) //add your xml link here, can also point to an xml file on the users computer

For this example, I'm going to have an xml file written like this-

    

<testxml>

<Login Username="Skyrocket" Key="1234"></Login>

<Login Username="DangeeJ" Key="4321"></Login>

</testxml>

Ok so we've created the xml file and opened it, now we need to get each node attribute, so we add this inside the button aswell-

    

XmlNodeList Login = Xml.GetElementByTagName("Login"); //gets everything inside <login>



Foreach (XmlNode node in Login)

{

String user = node.Attributes["UserName"].Value; //gets the value of username=



String Key =node.Attributes["Key"].Value;

And that's really it, now we just check whether the key & username matches another string, for this example I'm using 2 text boxes, so a basic login page. Add this-

    

If (user == textBox1.Text && Key == textBox2.Text)

{

MessageBox.Show("Logged In");

}

So basically what this does, is checks whether the value of Username and Key equals the same as both text boxes.

Like I said earlier, this is most defiantly a good idea for a login system, since anybody can access the xml file and steal users logins. MySQL etc is a much better alternative for that.

Xml reading has endless possibilities of what can be done with it, things such as custom key input, custom settings etc can be used within a local xml file which the user can edit.

Well that's about it! If I forgot anything, please do notify me since I created this thread on my phone (I'm sure some bits aren't fully c&p'able :p)

Thanks Skyrockett, always a post to help us beginners xD

Heres an example project which reads a key and a name from an xml file and checks it

Thanks
