TryXmlSerialize function

I was using XmlSerialize method from 
http://serialization.codebetter.com/blogs/brendan.tompkins/archive/2005/03/01/56244.aspx
for a while.
Recently I found that sometimes it's safer to use TryXmlSerialize:

    /// <summary>

    /// Serialize an object into XML

    /// </summary>

    /// <param name="serializableObject">Object that can be serialized</param>

    /// <returns>Serial XML representation</returns>

    public static bool TryXmlSerialize(object objectToSerialize, out string strXml)

    {

        bool bRet=true;

        try

        {

          strXml =XmlSerialize( objectToSerialize);

        }

        catch (Exception exc)

        {

            bRet=false;

            strXml=exc.ToString();

        }

        return bRet;

    }
