If-Else 語句只執行 else

Question

我正在嘗試使用 SteamKit2 為 Steam 創建一個聊天機器人。 我在一個文本文檔中有一組預定義的消息，程序可以讀取這些消息，但是當收到的消息不在此列表中時，我希望它說出特定的響應。 我嘗試使用 if-else 語句，但是當我向機器人發送消息時，它只回復 else 響應，而不是預定義的響應。

while ((rLine = sReader.ReadLine()) != null) {
    string text = rLine.Remove(rLine.IndexOf('|') - 1);  //message | response
    string response = rLine.Remove(0, rLine.IndexOf('|') + 2) ;
    string realText = text.ToLower();

    if (callback.Message.Contains(realText) || callback.Message.Contains(text))
    {
        steamFriends.SendChatMessage(callback.Sender, EChatEntryType.ChatMsg, response);
        Console.WriteLine("Someone has messaged me, and I replied with an automated message.");
        sReader.Close();
        return;
    } else {
        steamFriends.SendChatMessage(callback.Sender, EChatEntryType.ChatMsg, "I don't know what you mean. Could you maybe write it a bit differently? <3");
        Console.WriteLine("Someone has messaged me, and it wasn't on my auto-response list: {0}",callback.Message);
        sReader.Close();
        return;
    }
}

謝謝。

重新寫成這樣：

while ((rLine = sReader.ReadLine()) != null) {
    string text = rLine.Remove(rLine.IndexOf('|') - 1);  //message | response
    string response = rLine.Remove(0, rLine.IndexOf('|') + 2) ;
    string realText = text.ToLower();

    if (callback.Message.Contains(realText) || callback.Message.Contains(text))
    {
        steamFriends.SendChatMessage(callback.Sender, EChatEntryType.ChatMsg, response);
        Console.WriteLine("Someone has messaged me, and I replied with an automated message.");
        sReader.Close();
        return;
    }
}

steamFriends.SendChatMessage(callback.Sender, EChatEntryType.ChatMsg, "I don't know what you mean. Could you maybe write it a bit differently? <3");
Console.WriteLine("Someone has messaged me, and it    wasn't on my auto-response list: {0}",callback.Message);
sReader.Close();
return;
