    <p>So, according to CultureInfo class specifications, it is [Serializable]. However, when I have another [Serializable] class (say ClassA) that has a reference to a CultureInfo instance, and I try to create an XmlSerializer instance with ClassA, I get an exception. Anyone know a work around? I would assume since CultureInfo is [Serializable] the below should work.</p> <p>Many thanks!</p> <p>-- Code--</p> <pre><code>using System; using System.Xml.Serialization; using System.Globalization; namespace CultureInfoSerializationTest { class Program { static void Main(string[] args) { ClassA aClass = new ClassA(); aClass.UsedCulture = CultureInfo.CurrentCulture; try { XmlSerializer serializer = new XmlSerializer(typeof(ClassA)); } catch (Exception e) { } } } [Serializable] public class ClassA { public CultureInfo UsedCulture { get; set; } } } </code></pre> <p>--Exception--</p> <pre><code>System.InvalidOperationException was caught HResult=-2146233079 Message=There was an error reflecting type 'CultureInfoSerializationTest.ClassA'.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
