我如何解决该准则 [英] How Do I Solved The Code

问题描述

输入：Dim str As String =C：/ Ram / Ram1 / Ram2



这是一个硬编码输入，意味着我们想要的变量将其初始化为String。条件是我们只能使用一个打印选项。



输出：

C：/ Ram

C：/ Ram / Ram1

C：/ Ram / Ram1 / Ram2



请解决这个问题，为此我会感谢他/她。

Input : Dim str As String = "C:/Ram/Ram1/Ram2"

It is a hard coded input, means inside a variable we want to initialize this as a String. And the condition is we can use only one print option.

Output :
C:/Ram
C:/Ram/Ram1
C:/Ram/Ram1/Ram2

Please solve the question, for this i will be thankful to him/her.

推荐答案

最简单的方法是使用 string.Split [ ^ ]打破'/'处的字符串，然后从返回的数组中打印出来：

Easiest way is to use string.Split[^] to break the string at the '/' and then print it from the array that returns:

Dim str As String = "C:/Ram/Ram1/Ram2"
Dim parts As String() = str.Split("/"C)
Dim sb As New StringBuilder()
Dim sep As String = ""
For Each s As String In parts
    sb.AppendFormat("{0}{1}", sep, s)
    sep = "/"
    Console.Writeline(sb.ToString())
Next
