如何提取字符串的一部分并将其存储为arraylist？ [英] How do I extract a portion of the string and store it an arraylist?

问题描述

嗨：

我有一个文件数组，其中包含以下格式的字符串：



abc12345.xxx_xxx001.001045



以上述格式存储的字符串可以帮助我完成部分工作



现在，存储了这个，我想提取该字符串的一部分并将其存储为数组



如何从该字符串中单独提取abc12345并将其存储为数组？ />


我尝试了什么：



我尝试使用split命令。我面临的问题是：

PN（0）店铺abc12345

PN（1）店铺xxx_xx001

PN（2）店铺001045

我希望abc12345存储为PN（0），下一个后续部件号存储为PN（1）

Hi:
I have a file array which carries strings in the following format:

"abc12345.xxx_xxx001.001045"

The string stored in above format helps me do a portion of my job

Now, having stored this, I want to extract a portion of this string and store it an array

How do I extract "abc12345" alone from this string and store it an array?

What I have tried:

I tried using the split command. The problem am facing is:
PN(0) stores abc12345
PN(1) stores xxx_xx001
PN(2) stores 001045
I want abc12345 to be stored as PN(0) and next subsequent part number to be stored as PN(1)

Dim PN As New ArrayList()
For Each element In file1array
    PN = element.split("."c)

Next

推荐答案

我想你想要的是：

I think what you want is like:

Dim PN As New ArrayList()
Dim splitElement as String() = Nothing
For Each element In file1array
    splitElement = element.Split("."c, 1) ' you only want one anyway
    PN.Add(splitElement(0))
Next

你必须分别将 Split 结果添加到 ArrayList 。
