Question

我环顾四周，我认为这意味着休息无法到达，但我不明白它是如何无法到达或者它想要达到的目的。我得到错误的代码如下，也许有人可以告诉我要添加什么来使中断可达：

#region :buy <item>

case "buy":
    string Item = stringManager.wrapParameters(args, 1);

    if (Item == "bread") 
    {
        int foodfunds;
        int myfood;
        int foodCheck;
        int creditCheck;
        using (DatabaseClient dbClient = Eucalypt.dbManager.GetClient())
            foodfunds = dbClient.getInt("SELECT credits FROM users WHERE name = '" + _Username + "'");
        using (DatabaseClient dbClient = Eucalypt.dbManager.GetClient())
            myfood = dbClient.getInt("SELECT food FROM users WHERE name = '" + _Username + "'");
        if (foodfunds < 10)
        {
            Room.sendData("BK" + "Not enough cash.");
        }
        if (_roomID != 193)
        {
            sendData("BK" + "You must be in the supermarket to buy bread");
        }
        else
        {
            using (DatabaseClient dbClient = Eucalypt.dbManager.GetClient())
                dbClient.runQuery("UPDATE users SET food = food + 1 WHERE name = '" + _Username + "'");
            using (DatabaseClient dbClient = Eucalypt.dbManager.GetClient())
                foodCheck = dbClient.getInt("SELECT food FROM users WHERE name = '" + _Username + "'");
            using (DatabaseClient dbClient = Eucalypt.dbManager.GetClient())
                dbClient.runQuery("UPDATE users SET credits = credits - 10 WHERE name = '" + _Username + "'");
            using (DatabaseClient dbClient = Eucalypt.dbManager.GetClient())
                creditCheck = dbClient.getInt("SELECT credits FROM users WHERE name = '" + _Username + "'");
            Room.sendShout(roomUser, "*Buys a loaf of bread and stashes in bag*");
            Room.sendSaying(roomUser, "(Now have: " + foodCheck + " loaves of bread)");
            Room.sendSaying(roomUser, "(Now have: " + creditCheck + " credits left)");
        }
        if (myfood > 255)
        {
            Room.sendData("BK" + "You cannot carry anymore food!");
        }
        break;
    }
#endregion

Answer 1

该错误意味着在某些情况下break;不会被击中。

具体来说，if (Item == "bread")不是真的。

Answer 2

将break移到最后}之外。使用您的代码，如果项目不是“面包”，则无法访问break。
