<number>20</number>
<number>30</number>
<number>69</number>

The above mention numbers in XML file, i want to store in array.

I'm willing to bet one of the experts familiar with LINQ can come in here and post a better method (I'm pretty sure I've seen them do something like this), but the way I'm familiar with involves just parsing the XML.

There are two classes you'll want to take a look at:

http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx

http://msdn.microsoft.com/en-us/library/system.xml.xmlnode.aspx

That XML would be contained by some kind of parent node... I don't know what it is, but lets say it looks something like this:

<array>
<number>1</number>
...
</array>

In this example, you would parse your XML. If you encountered a node named array you could then call a method to parse that node. To get this into an array, it's just a matter of looping through the child nodes on that array and adding their values to an array which you can return from your method.

I hope this gives you some ideas... let me know if you have any trouble getting the code going.

Thanks!

You can use XMLReader Class to read data from XML files and then you can store data in arrays while reading.

Using LinQ you could do it like

int[] arr = XDocument.Load(@"C:\xxx.xml").Root.Elements("number").Select(element => int.Parse(element.Value)).ToArray();

But you'd need to have a root-element (as Gary suggested "array") otherwise XDocument.Load would fail.
