显示阵列/列表的内容

Question

I'm looking for a way to display (in the MsgBox or other read-able place) the array/list content, the list contains only strings:

Dim list As New List(Of String)

I would like to display the content of it in the MsgBox for now. I can convert the list to the array if there would be a need. Is there a way to do this?

Answer 1

You can declare a variable and loop the array putting every element inside:

Dim sResult As String = ""

For Each elem As String In list
    sResult &= elem & " "
Next

Or you can use String.Join() to directly merge all the elements of the array (you will need to convert the List to a normal array if using .NET framework before 4.0):

Dim sResult As String = String.Join(", ", list.ToArray())

Answer 2

How many elements are in that List? If they are few then a MessageBox could do

Dim message = string.Join(Environment.NewLine, list.ToArray())
MessageBox.Show(message)

If there are many, then you need some kind of interface to display everything.
In this case you need at least a WinForm application with your user defined Form that contains a TextBox with its multiline property set to true.

Dim message = string.Join(Environment.NewLine, list.ToArray())
textBox1.Text = message
