将保存的数字字符串转换为整数数组 [英] convert saved string of numbers into an array of integers

问题描述

在名为num_str的变量中，我有一个逗号分隔的数字字符串。

i have a comma separated string of numbers inside of a var named num_str

num_str的内容如下： 1,2,3,4,5 etc

the contents of num_str looks like this: "1,2,3,4,5" etc

我正在寻找一种将num_str添加到表达式中以将其中包含的数字形式转换为整数数组的方法

i am looking for a way to add num_str to an expression to convert the sting of numbers contained therein to an array of integers

我想确保我可以简单地引用'num_str'来获取数字，而不是像{ 1,2,3,4,5}那样拼写出来

i want to make sure i can simply reference 'num_str' to get the numbers from instead of spelling it out like {"1,2,3,4,5"}

我已经尝试过，其中'num_str'包含数字

i have tried this, where 'num_str' contains the numbers

Dim test As String = Nothing
Dim result() As Integer = Int32.TryParse(num_str.Split(","c))
For i = 0 To result.Length - 1
   test += result(i)
Next

但这不起作用

我要查找的是带有数字数组的结果

what i am looking for is a result with an array of numbers

推荐答案

Dim totalValue = str.
                 Split(","c).
                 Select(Function(n) Integer.Parse(n)).
                 Sum()
