加入整数数组

Question

在Integer数组级别中获取逗号分隔的整数列表的最简单/最佳实践方法是什么？

Dim levels(5) As Integer
Dim levelsStr As String

'put values in levels'

'Attempt 1: Failed'
levelsStr = String.Join(", ", levels) ' <- Error on levels'
'Value of type "1-dimensional array of Integer" cannot be converted'
'to "1-dimensional array of String" because "Integer" is not derived'
'from "String".'

Answer 1

试试这个

levelsStr = String.Join(", ", levels.Select(Function(x) x.ToString()).ToArray())
