C# 如何獲取可執行文件路徑的上上級目錄

1、

DirectoryInfo di = new DirectoryInfo(string.Format(@"{0}..\..\", Application.StartupPath));

di.FullName

就是你想要的

..\有幾個就是往回退幾層

2、

DirectoryInfo info = new DirectoryInfo(Application.StartupPath);

String path = info.Parent.Parent.FullName;

 

3、

 

string WantedPath = Application.StartupPath.Substring(0,Application.StartupPath.LastIndexOf(@"\"));
