首字母被截断

Question

（我对编码非常陌生，因此请尽量保持基本答案。）

我正在做一个GamerTag检查器，尝试连接到xbox.com/blahblahblah/gamertag，如果它返回了gamertag的个人资料，则表示它已被占用。

当您键入第一个游戏玩家标签时，它就起作用了。但是，当您输入第二个时，它不是。

Sub Main()
    Console.ForegroundColor = ConsoleColor.Yellow
    Console.WriteLine("DiamondHacks's Gamertag Checker!")
    Console.ForegroundColor = ConsoleColor.Magenta
    Console.WriteLine("Spaced Gamertags do NOT work :(")
    Console.ForegroundColor = ConsoleColor.Blue
    Console.WriteLine("Just type a word, and it will check if it is available! :)")
    Console.ForegroundColor = ConsoleColor.Green
    Console.WriteLine("Good Luck getting some OG Gamertags :)")
    Console.ForegroundColor = ConsoleColor.Cyan

在呼叫Console.Read()之前，您呼叫到时blahblah()正在咀嚼下一行的第一个字符。
