How to get last value of split string-array? [VB.net]
提问by user3565290
Alright so I have this:
好的，所以我有这个：
Dim OldString As String = "Word<>Car<>Test<>"
Dim NewString As String() = OldString.Split("<>")
Now I want to get the last value of OldString, which would be "Test", just before you ask, the last "<>" after "Test" has to be there, no matter what. Everytime a new string would get added to the array, it would add "VALUE<>", in my case there's no way around it.
现在我想获得 OldString 的最后一个值，也就是“Test”，就在你问之前，“Test”之后的最后一个“<>”必须在那里，无论如何。每次将新字符串添加到数组时，它都会添加“VALUE<>”，在我的情况下没有办法绕过它。
I only need the last value, but without knowing how many values the string-array has,
means I cannnot do something like NewString(2)or similar, since I don't know how many
values the string-array has...
我只需要最后一个值，但不知道字符串数组有多少个值，意味着我不能做类似NewString(2)或类似的事情，因为我不知道字符串数组有多少个值......
I am stuck and I've been trying things for hours, I hope you guys can help me out, thanks!
我被卡住了，我已经尝试了几个小时，希望你们能帮助我，谢谢！

You need to fix your split statement:
您需要修复 split 语句：
Dim NewString As String() = OldString.Split(New String() {"<>"}, StringSplitOptions.None)
You can loop through the NewString arrary like this:
您可以像这样遍历 NewString 数组：
For Each lstrString as String in NewString
if ( String.IsNullOrEmpty(lstrString) = False) then
Console.WriteLine("This is a value: " + lstrString)
end if
Next
'Get the length of NewString like this
'像这样获取NewString的长度
Dim lngth as integer = NewString.length()
'Get the last value
'获取最后一个值
Dim lstrLastValue as string = NewString(lngth - 1) 'Or maybe -2 in your case
