Hi Guys

i'm trying to write a generic function which should be able to parse a xml file

here is the code

        public struct XmlArg


            public string Name;

            public Type T;

            public object Value;



        static bool ParseXmlArgs(XmlReader xml, params XmlArg[] args)


            for (int i = 0; i < args.Length; ++i)


                if (xml.MoveToContent() != XmlNodeType.Element || xml.Name != args[i].Name)


                    return false;


                args[i].Value = xml.ReadElementContentAs(args[i].T, null);


            return true;



        static void Main(string[] args)


            int a = 0;




                new XmlArg[]{

            new XmlArg() { Name = "ErrorCode", T = typeof(int), Value = a}});


i know that i should pass a's pointer to Value ( it's type should be some different type other than object of course )

but i don't want it to be non-managed way.

is there any managed way to use a variable's pointer in structure ?

create an array, pass it to a method, and then read its contents afterwards:

You need to construct the XmlArg[] array before calling the method, and forget about the a variable until the parsing if finished:

var reader = XmlTextReader.Create("C:\\Users\\Yazilim\\Desktop\\XML.xml");
var results = new []
    new XmlArg() { Name = "ErrorCode", T = typeof(int) },
    new XmlArg() { Name = "ErrorMessage", T = typeof(string) }

if (ParseXmlArgs(reader, results) == true)
    // results were passed by reference, so do something with these values
