How can I get the value of an enum for its integer value?

In recent versions of .NET, I can retrieve the enum value this way:

C#

public enum Packers
{
    Aaron_Rodgers = 12,
    Eddie_Lacy = 26,
    Jordy_Nelson = 87,
    Candle_Robb = 18,
    Clay_Matthews = 52,
    Julius_Peppers = 56
};

private void button4253147968_Click(object sender, EventArgs e)
{
    int packerNum = Convert.ToInt32(textBoxPackerNum.Text);
    String packerName = Enum.GetName(typeof(Packers), packerNum);
    MessageBox.Show(String.Format("Packer with number {0} is {1}", packerNum, packerName));
}

Entering "52" in textBoxPackerNum shows me "Packer with number 52 is Clay_Matthews" etc.

However, GetName() is not available for Enum in .NET 3.5

What can be done in older versions of .NET to retrieve this value?

GetName is there since 2.0 - http://msdn.microsoft.com/en-us/library/system.enum.getname(v=vs.80).aspx

Strange...it won't compile, not does it afford me a "Resolve" with the context menu...maybe because the target platform is Windows CE; I should have mentioned that, I reckon.

Enum.ToObject(typeof(Packers), 52).ToString();
This should work on any CF version...

Yep, that works:

Packers pickedAPeckOfPickledPeppers = Packers.Julius_Peppers;
String s = Enum.ToObject(typeof(Packers), pickedAPeckOfPickledPeppers).ToString();
MessageBox.Show(String.Format("Packer passed is {0}", s));

Just cast it.

First of all, this is not what's Enum for. Using enum for such a task is really not a good idea. Let's suppose you have pnly given us a bad example...

This is working in 3.5 (and 3.5 CF) also:

C#

int x = 52;
Console.WriteLine(((Packers)x).ToString());

If you want to have something similar like GetNames in CF, start here: http://www.nickharris.net/index.php/2010/01/07/enum-getnames-in-net-compact-framework-3-5/[^] and here: http://stackoverflow.com/questions/8835264/how-to-enum-getvalues-in-net-3-5[^]
