How to quickly save/load class instance to file

Question

I have several collections of classes/structs in my app.

The class is just a class with fields

class A
{
  public int somevalue;
  public string some

Old topic, but I modified Tim Coker's answer above to utilize the using blocks to properly dispose of the stream objects and save only a single class instance at a time:

public static T Load(string FileSpec) {
    XmlSerializer formatter = new XmlSerializer(typeof(T));

    using (FileStream aFile = new FileStream(FileSpec, FileMode.Open)) {
        byte[] buffer = new byte[aFile.Length];
        aFile.Read(buffer, 0, (int)aFile.Length);

        using (MemoryStream stream = new MemoryStream(buffer)) {
            return (T)formatter.Deserialize(stream);
        }
    }
}

public static void Save(T ToSerialize, string FileSpec) {
    Directory.CreateDirectory(FileSpec.Substring(0, FileSpec.LastIndexOf('\\')));
    FileStream outFile = File.Create(FileSpec);
    XmlSerializer formatter = new XmlSerializer(typeof(T));

    formatter.Serialize(outFile, ToSerialize);
}
