Possible to validate xml against xsd using code at runtime?

Question

I have xml files that I read in at runtime, is is possible to validate the xml against an xsd file at runtime? using c#

Answer 1

I GOT CODE TOO! I use this in my tests:

    public static bool IsValid(XElement element, params string[] schemas)
    {
        XmlSchemaSet xsd = new XmlSchemaSet();
        XmlReader xr = null;
        foreach (string s in schemas)
        { // eh, leak 'em. 
            xr = XmlReader.Create(
                new MemoryStream(Encoding.Default.GetBytes(s)));
            xsd.Add(null, xr);
        }
        XDocument doc = new XDocument(element);
        var errored = false;
        doc.Validate(xsd, (o, e) => errored = true);
        if (errored)
            return false;

        // If this doesn't fail, there's an issue with the XSD.
        XNamespace xn = XNamespace.Get(
                      element.GetDefaultNamespace().NamespaceName);
        XElement fail = new XElement(xn + "omgwtflolj/k");
        fail.SetAttributeValue("xmlns", xn.NamespaceName);
        doc = new XDocument(fail);
        var fired = false;
        doc.Validate(xsd, (o, e) => fired = true);
        return fired;
    }

This one takes in the schemas as strings (file resources within the assembly) and adds them to a schema set. I validate and if its not valid I return false.

If the xml isn't found to be invalid, I do a negative check to make sure my schemas aren't screwed up. Its not guaranteed foolproof, but I have used this to find errors in my schemas.
