Help with Switch and Enum

Very new to C#. I'm creating an indicator for an application built in .Net. I'm creating a parameter which is essentially a drop down menu for the indicator settings. It has to be added as an enum in a different namespace to the main code.

namespace EnumsP
{
public enum EnumList
{
[Description("description here")]
One,
[Description("description here")]
Two,
[Description("description here")]
Three
}

Here is the code that creates the dropdown

// PARAMETER
[NinjaScriptProperty]
[TypeConverter(typeof(EnumsP.EnumDescriptionConverter))]
[PropertyEditor("NinjaTrader.Gui.Tools.StringStandardValuesEditorKey")]
[Display(Name = " Option drop down", Description = "")]
public EnumsP.EnumList orange
{ get; set; }

So far so good. The variable orange is now available to me in the main namespace. The problem I have is I don't know how to get the data correctly from the variable 'orange' in a switch.

pears = orange switch
{
One => 100,
Two => 10,
Three => 1
};

Print(Convert.ToString(orange));

The Print works fine. I see 'One', 'Two' or 'Three' in the console depending on what the user chose. But When I try to pass the variable to 'pears' I get the error "The name One/Two/Three does not exist in the current context".

I guess orange is an enum, and I don't know how to pass this to another variable I create as I don't know what type I need.
