Split an array in Visual Basic
提问by AAA
I have a list of names with scores in lstInput (a listbox) that looks something like this:
我在 lstInput（一个列表框）中有一个带有分数的名字列表，看起来像这样：
Name1,100,200,300
Name2,100,200,300
Name3,100,200,300
...etc...
...等等...
I need to split the array into a string and print the results of the person's name and the scores that are separated by a comma.
我需要将数组拆分为一个字符串，并打印出人名的结果和以逗号分隔的分数。
What I have so far is the following:
到目前为止，我所拥有的是以下内容：
For s As Integer = 0 To lstInput.Items.Count - 1
lstOutput.Items.Add(lstInput.Items(s))
Next
Now, that displays the entire list, but I need to split the list into strings so that they display on their own: e.g. Name1 100 200 300
现在，这会显示整个列表，但我需要将列表拆分为字符串，以便它们自己显示：例如 Name1 100 200 300
...etc..
...等等..

I may be going crazy, but I think the OP wants something like this:
我可能会发疯，但我认为 OP 想要这样的东西：
For s As Integer = 0 To lstInput.Items.Count - 1
lstOutput.Items.Add(String.Join(" ", CType(lstInput.Items(s), String).Split(",")))
Next
Purpose of this code is unknown but it ultimately removes commas, so this Name1,100,200,300becomes this Name1 100 200 300(just following the question). Guess I could have done String.Replaceinstead, but it's not as cool.
这段代码的目的是未知的，但它最终删除了逗号，所以这Name1,100,200,300变成了这个Name1 100 200 300（只是在问题之后）。我猜我本来可以这样做的String.Replace，但它没有那么酷。

For s As Integer = 0 To lstInput.Items.Count - 1
dim items As String() = lstInput.Items(s).Split(",".ToCharArray()) 'splits into array of 4 elements
dim name As String = items(0) 'first element is name
dim score1 As String = items(1) 'second element is first score
-- now do the rest yourself
-- listOutput.Items.Add( concatenate name and the scores here)
Next
