使用列表时发生的错误 [英] Errors occurring when using list

问题描述

我有一个列表，我使用此代码输入了五个项目:

I have a list that I have entered five items into using this code:

     If (surname.Count + 1) < noofcompetitors Then
            surname.Add(txtSurname.Text)
     Else....

我正在尝试使用此代码查看这些项目:

I am attempting to see these items using this code:

     Console.WriteLine(surname.Item(0))
     Console.WriteLine(surname.Item(1))
     Console.WriteLine(surname.Item(2))
     Console.WriteLine(surname.Item(3))
     Console.WriteLine(surname.Item(4))  

但是，我收到错误System.ArgumentOutOfRangeException".

However, I get the error 'System.ArgumentOutOfRangeException'.

推荐答案

为什么不使用 for each 循环?

Why not just use a for each loop?

    For Each name As String In surname
        Console.WriteLine(name)
    Next

这样你就不会得到异常，你可以看到实际上有多少名字被添加到你的列表中

That way you won't get the exception and you can see how many names are actually being added to your list
