Attribute 给枚举添加备注

public class RemarkAttribute : Attribute
{
private string m_remark;
public RemarkAttribute(string remark)
{
this.m_remark = remark;
}
public string Remark
{
get { return m_remark; }
set { m_remark = value; }
}

{
Type type = val.GetType();
FieldInfo fd = type.GetField(val.ToString());
if (fd == null)
return string.Empty;
object[] attrs = fd.GetCustomAttributes(typeof(RemarkAttribute), false);
string name = string.Empty;
foreach (RemarkAttribute attr in attrs)
{
name = attr.Remark;
}
return name;
