如何在实体框架中找到属性映射到的表和列？

Question

How do I get the information from ObjectContext.Metadata at runtime to find what column in what table a property on an object is mapped to?

EDIT:

I'm happy if this only works for entities that map to one and only one table.

This doesn't use MetaData, but here's how I do it :)

using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;

    public static string GetFullTableName(this Type t)
    {

        string exp = "[{0}].[{1}]";

        if (Attribute.IsDefined(t, typeof(TableAttribute)))
        {
            var attr = (TableAttribute)t.GetCustomAttributes(typeof(TableAttribute), false).First();
            return string.Format(exp, attr.Schema, attr.Name);
        }
        else
        {
            return string.Format("[dbo].[{0}]", t.Name);
        }
    }
