将字节转换为ascii然后将字符串转换为缺少字符

Question

此程序通过给定密码打开隐藏文件夹。如果您是第一次运行此程序，则用户应输入“＆＃39; new＆＃39;创建一个保存其密码和目录路径的帐户，然后，当他再次运行并输入密码时，该目录将在文件资源管理器上打开。我的问题是，当我输入＆＃39;我尝试通过我的程序打开它，随机目录打开。

发生了什么：
输入： C：\ Users \ joao_.DESKTOP-QMLOLSI \ Desktop \ League of Legend 输出：C：\ Users

会发生什么：
输入： C：\ Users \ joao_.DESKTOP-QMLOLSI \ Desktop \ League of Legend 输出 C：\ Users \ joao_.DESKTOP-QMLOLSI \ Desktop \ League of Legends
