    string literals in C#

    I have a huge xml file from which the key and value attributes are selected among other things.

    foreach (
    XmlNode node in 
      ConfigProductCode cpc = new ConfigProductCode();
      XmlAttribute keyAttr = node.Attributes["key"];
      XmlAttribute valAttr = node.Attributes["value"];
    // etc
    How does C# handle the instantiation of literal strings? does it make a new object with allocating heap memory on every iteration or just once?

    My understanding is that string literals aren't instantiated. They're just referenced from the assembly. Your method shouldn't incur any runtime cost.
    If you understand what you're doing, you're not learning anything.

    Might I suggest using serialization for the xml file as opposed to parsing it manually through the DOM?
