有没有办法我可以使用类似的东西？运算符在这里检查值并运行这两个中的任何一个而无需使用两个if语句？

Question

我有这段代码，我想找到一种方法来尽可能地清理它。希望人们提出以下建议：

if (App.viewablePhrases.Count() == 1)
{
    await SetMessageAsync(
            msgType: "Practice",
            msg1: "Practice Mode",
            msg2: $"You have 1 card viewable out of {selCds} {msg}\n\nThe card in your deck has a total of {selPts} {ptsMsg1} {ptsMsg2}",
            btnText: App.cardsViewed ? "Continue Practice" : "Start Practice ");
    return true;
}

if (App.viewablePhrases.Count() > 1)
{
    await SetMessageAsync(
            msgType: "Practice",
            msg1: "Practice Mode",
            msg2: "You have " + App.viewablePhrases.Count() + " cards viewable out of a total of " + selCds + msg +
                  "\n\nThe cards in your deck have a total of " + selPts + ptsMsg1 + ptsMsg2,
            btnText: App.cardsViewed ? "Continue Practice" : "Start Practice ");
    return true;
}

如果条件只是用调用SetMessageAsync()方法App.viewablePhrases.Count()，只需1从字符串中删除硬编码的值并使用App.viewablePhrases.Count()。

if(App.viewablePhrases.Count() > 0)
{
    var cardString =  App.viewablePhrases.Count() == 1 ? "card" : "cards";
    await SetMessageAsync(
      msgType: "Practice",
      msg1: "Practice Mode",
      msg2: $"You have {App.viewablePhrases.Count()} {cardString} viewable out of {selCds} {msg}\n\nThe {cardString} in your deck has a total of {selPts} {ptsMsg1} {ptsMsg2}",
                        btnText: App.cardsViewed ? "Continue Practice" : "Start Practice ";
    return true;
}
