news:XZ********************@news20.bellglobal.com: I have been wondering is it possible to get the datatype of an
enumeration without using reflection. To clearify if I do:
enum Genders
{
Male,
Female
}
What I want is to return the value Genders not System.Int32. Is
there a
way of doing this without reflection or should I add reflection to my
program to handle this. If I use reflection what should I be looking
for to help with this?
Why would you want to do this? Couldn't you just use a hard-coded
string?
Enum's aren't like classes. If you have an enum variable, you always know
what type of enum it is. I can't imagine any situation in which you would
treat it as a generic enum (or if its even possible).

The thing is I'm trying to create a groupbox that acts much like the
groupbox in access 2000 with the Value property. But now that I have done
that I want to automate loading the groupbox with an enumeration. I have my
radio buttons being populated properly but I want to automate loading the
text property of the Groupbox. Here is the code for my new groupbox maybe
someone can help point out a way of doing this that won't be terribly taxing
for the user.
using System;
using System.Drawing;
using System.Windows.Forms;
namespace OptionSelectBox
{
/// <summary>
/// OptionSelectBox.
/// </summary>
public class OptionSelectBox : System.Windows.Forms.GroupBox
{
public OptionSelectBox()
{
//
// The InitializeComponent() call is required for Windows Forms designer
support.
//
InitializeComponent();
}
public Enum DataSource
{
set
{
if (this.Controls.Count < 1)
{
System.Array values = Enum.GetValues(value.GetType());
for (int i = 0; i < values.Length; i++)
{
System.Windows.Forms.RadioButton rdoButton = new
System.Windows.Forms.RadioButton();
rdoButton.Left = 5;
if (this.Controls.Count > 0)
{
rdoButton.Top = this.Controls[this.Controls.Count - 1].Top +
this.Controls[this.Controls.Count - 1].Height + 5;
}
else
{
rdoButton.Top = 20;
rdoButton.Checked = true;
// I want to set the groupbox name here.
}
rdoButton.Tag = values.GetValue(i);
rdoButton.Text = rdoButton.Tag.ToString();
this.Controls.Add(rdoButton);
}
}
this.Width = this.Controls[0].Width + 10;
this.Height = this.Controls.Count * (this.Controls[0].Height + 5) + 20;
}
}
public object Value
{
get
{
foreach (System.Windows.Forms.RadioButton rdoButton in this.Controls)
{
if (rdoButton.Checked == true)
{
return rdoButton.Tag;
}
}
return null;
}
}
