change an attribute value of a XML file in c#

how I can change the attribute "id" using my source code?

static void Main(string[] args)
    {

        XmlTextReader reader = new XmlTextReader(@"C:\Users\1.xml");
        XmlNodeList elementList = reader.
        while (reader.Read())
        {
            switch (reader.NodeType)
            {
                case XmlNodeType.Element: // The node is an element
                    {
                        reader.ReadToFollowing("command"); 
                        reader.MoveToAttribute("id");                         
                        Console.Write(reader.Value);
                        Console.WriteLine(" ");                    
                    }
                    break;
            }
        }           
        Console.Read();
    }

I saw some examples, but they have used another methods that don't work with mine. (I'm a noobie)

Code above didn't fly for me

this works thought 

var doc = XDocument.Load(path);
    foreach(var element in doc.Descendants("command"))
    {
        element.Attribute("id").Value = id;
    }

doc.Save(path);

Hope this saves you some time.

I would use LINQ to XML

XElement doc=XDocument.Load(path);
foreach(var element in doc.Descendants().Elements("command"))
{
element.Attribute("id").Value=yourValue;
}
doc.Save(path);

This would change each command element's id attribute
