using System; using System.IO; using System.Xml; namespace Task3 { class TextFileReader { static void Main(string[] args) { XmlTextReader reader = new XmlTextReader("my.xml"); String strn, strsn; while (reader.Read()) { switch (reader.NodeType) { case XmlNodeType.Element: // The node is an element. if (reader.HasAttributes) { //Console.WriteLine(reader.GetAttribute("reader.Name")); strn = reader.GetAttribute(0); strsn = reader.GetAttribute(1); //Console.WriteLine(strn); //Console.WriteLine(strsn); } break; } } int counter = 0; string line; // Read the file and display it line by line.

Console.ReadLine(); } } }this is my code to raed from a text file, and then replace the value in it from the xml file, but it is giving some error, that
"Use of unassigned local variable 'strn'"
