Enum boolean in C#

I have this method 

public enum Values
{
    True= true,
    False=false
};
public static string GetValues(bool values)
{
    string status = "";
    switch (values)
    {
        case(bool)UIHelper.Values.False:

    }
}

I want to have this enum as boolean. It says, that:

Values cannot be casted as bool.

How can I do it so I can have it boolean?

If you have to stick to enum you can implement an extension method:

  public enum Values {
    True,
    False,
    // and, probably, some other options
  };

  public static class ValuesExtensions {
    public static bool ToBoolean(this Values value) {
      // which options should be treated as "true" ones
      return value == Values.False;
    }
  }

...

// you, probably want to check if UIHelper.Values is the same as values 
if (values == UIHelper.Values.ToBoolean()) {
  ...
}

Use 0 for false and 1 for true instead combined with Convert.ToBoolean

true if value is not zero; otherwise, false.

public enum UnlPointValues
{
    Serial = 1,  //true
    Service = 0  //false
};

public static string GetUnloadingPointValues(bool values)
{
    string status = "";
    switch (values)
    {
        case (Convert.ToBoolean((int)UIHelper.UnlPointValues.Serial)):
        break;
        case (Convert.ToBoolean((int)UIHelper.UnlPointValues.Service)):
        break;
    }
}

I don't see that you need an enum here.

public static string GetUnloadingPointValues(bool isSerial)
{
    return isSerial ? "Serial" : "Service";
}

Or whatever string values you want to map.

Of course, you can map to 0 (Service) and 1 (Serial), but why map to that in the first place? Why not use bool from the start?

public static class UnlPointValues
{
    public const bool Serial = true;
    public const bool Service = false;
}

public static string GetUnloadingPointValues(bool values)
{
    string status = "";
    switch (values)
    {
        case UIHelper.UnlPointValues.Serial:

    }
}
