我如何解决该准则

本文介绍了我如何解决该准则的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

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

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
