Can't overlay 2nd Enum value on int?

I do not understand. I managed to pass the first enum int value, but not the second?

public enum PayPalTransactionType
{
    Authorization = 0, // Debit
    Capture = 1, // Credit
    Refund = 2,
    Void = 3
}

public string GetPayPalTransCode(PayPalServiceBase.PayPalTransactionType payPalTransactionType)
{
    string actionCode = string.Empty;

    switch (payPalTransactionType)
    {
        case (int)PayPalServiceBase.PayPalTransactionType.Authorization:
            actionCode = "Debit";
            break;
        case (int)PayPalServiceBase.PayPalTransactionType.Capture:
            actionCode = "Credit";
            break;
    }

    return actionCode;
}

in my second case, I get this casting error:

Cannot implicitly convert type intto PayPalTransactionType. there is an explicit conversion (are you missing a listing?)

Why are you trying to quit first? Just leave this as an enumeration value everywhere:

public string GetPayPalTransCode
    (PayPalServiceBase.PayPalTransactionType payPalTransactionType)
{
    string actionCode = string.Empty;

    switch (payPalTransactionType)
    {
        case PayPalServiceBase.PayPalTransactionType.Authorization:
            actionCode = "Debit";
            break;
        case PayPalServiceBase.PayPalTransactionType.Capture:
            actionCode = "Credit";
            break;
    }

    return actionCode;
}

In addition, I will have an explicit default action for unrecognized codes and just come back directly:

public string GetPayPalTransCode
    (PayPalServiceBase.PayPalTransactionType payPalTransactionType)
{
    switch (payPalTransactionType)
    {
        case PayPalServiceBase.PayPalTransactionType.Authorization:
            return "Debit";
        case PayPalServiceBase.PayPalTransactionType.Capture:
            return "Credit";
        default:
            return ""; // Or throw an exception if this represents an error
    }
}

Alternatively you can use Dictionary<PayPalTransactionType, string>.
