XmlSerializer Performance Issue when Specifying XmlRootAttribute

Question

I\'m currently having a really weird issue and I can\'t seem to figure out how to resolve it.

I\'ve got a fairly complex type which I\'m trying to serialize

Answer 1

Just had to implement something like this and used a slightly more optimized version of @Dougc's solution with a convenience overload:

public static class XmlSerializerCache {
    private static readonly Dictionary cache = new Dictionary();

    public static XmlSerializer Get(Type type, XmlRootAttribute root) {
        var key = String.Format("{0}:{1}", type, root.ElementName);
        XmlSerializer ser;
        if (!cache.TryGetValue(key, out ser)) {
            ser = new XmlSerializer(type, root);
            cache.Add(key, ser);
        }
        return ser;
    }

    public static XmlSerializer Get(Type type, string root) {
        return Get(type, new XmlRootAttribute(root));
    }
}
