EF 中擷取 TableAttribute的值，即資料庫中真實的表名

 

比如EF中我定義了這樣一個實體：

 

    [Table(Name = "MyTableName")]    public class MyClass    {    }

 

現我想擷取 MyTableName,可以這樣來辦：

 

using System.Data.Linq.Mapping;namespace MyEF{    class Program    {        static void Main(string[] args)        {            string name = typeof(MyClass).GetAttributeValue((TableAttribute ta) => ta.Name);            Console.WriteLine(name);            Console.Read();        }    }    public static class AttributeExtensions    {        public static TValue GetAttributeValue<TAttribute, TValue>(            this Type type,            Func<TAttribute, TValue> valueSelector)            where TAttribute : Attribute        {            var att = type.GetCustomAttributes(                typeof(TAttribute), true            ).FirstOrDefault() as TAttribute;            if (att != null)            {                return valueSelector(att);            }            return default(TValue);        }    }    [Table(Name = "MyTableName")]    public class MyClass    {    }}
