I have a small method that looks like this:
public void SetOptions<T>() where T : Enum
{
int i = 0;
foreach (T obj in Enum.GetValues(typeof(T)))
{
if (i == 0)
DefaultOption = new ListItem(obj.Description(), obj.ToString());
i++;
DropDownList.Items.Add(new ListItem(obj.Description(), obj.ToString()));
}
}
Basically, I populate a dropdown list from an enum. Description()
is actually an extension method for enums, so T
is definitely an enum
.
However, I want to cast obj
just as you would any enum to its index like this (int)obj
, but I get an error saying I can't convert T to int. Is there a way to do this?
try this,
public void SetOptions<T>()
{
Type genericType = typeof(T);
if (genericType.IsEnum)
{
foreach (T obj in Enum.GetValues(genericType))
{
Enum test = Enum.Parse(typeof(T), obj.ToString()) as Enum;
int x = Convert.ToInt32(test); // x is the integer value of enum
..........
..........
}
}
}
