'我只是不知道为什么这不起作用

您正在拨打Console.ReadLine()两次。你需要删除第一个，或者设置一个等于第一个的变量（并删除第二个），然后检查它是否等于"list"。

示例：

Console.WriteLine("Choose a city. (if you need help, type list for a list of cities you can destroy.)")
Dim cityList As String = "new york city, carmel, LA, chicago. (we only support detonations for new york city at this point in time.)"

If Console.ReadLine = "list" Then
    Console.WriteLine(cityList)
    Console.ReadLine()
End If

或存储变量：

Console.WriteLine("Choose a city. (if you need help, type list for a list of cities you can destroy.)")
Dim input As String = Console.ReadLine() ' Store the variable
Dim cityList As String = "new york city, carmel, LA, chicago. (we only support detonations for new york city at this point in time.)"

If input = "list" Then ' Check the stored input
    Console.WriteLine(cityList)
    Console.ReadLine()
End If
