Visual Basic String Array Alphabetical Sort
提问by LyanR
I am trying to make a basic console application that allows the user to input 3 names, and then sort it alphabetically. This is not working.
我正在尝试制作一个基本的控制台应用程序，它允许用户输入 3 个名称，然后按字母顺序对其进行排序。这是行不通的。
Here is my code.
这是我的代码。
Dim names(2) As String
Console.WriteLine("Name 1 ?")
names(0) = Console.ReadLine
Console.WriteLine("Name 2 ?")
names(1) = Console.ReadLine
Console.WriteLine("Name 3 ?")
names(2) = Console.ReadLine
Array.Sort(names)
Console.WriteLine("Your names are:" & names)
The console is not printing the code.
控制台不打印代码。

Using LINQ:
使用 LINQ：
Dim namesSorted() As String = names.OrderBy(Function(x) x).ToArray
With this approach you can change sort criteria to anything you want, i.e. word length, ascending/descending. To print the results:
使用这种方法，您可以将排序标准更改为您想要的任何内容，即字长、升序/降序。打印结果：
Console.WriteLine("Your names are:" & String.Join(","c, namesSorted))
Also, I suggest you use List instead, then you are not limited to just 3 names, and you don't need to know how many names you will be processing in advance. LINQ syntax will be the same.
另外，我建议你改用List，这样你就不仅限于3个名字，而且你不需要提前知道你将处理多少个名字。LINQ 语法将是相同的。

Try something like this...
尝试这样的事情......
Dim names(2) As String
Console.WriteLine("Name 1 ?")
names(0) = Console.ReadLine
Console.WriteLine("Name 2 ?")
names(1) = Console.ReadLine
Console.WriteLine("Name 3 ?")
names(2) = Console.ReadLine
Array.Sort(names)
Console.WriteLine("Your names are:")
For x = 0 To 2
Console.WriteLine(names(x))
Next x
