如何通过在 c# 中使用 AppDomain.CurrentDomain.BaseDirectory 在文件夹路径中上一步

Question

I am using AppDomain.CurrentDomain.BaseDirectory and I want to go one step backwards but couldn't figure out how? Below is the example,

CODE :

string path = AppDomain.CurrentDomain.BaseDirectory;

RESULT :

"C:\\\\Mainline Code\\\\IxExpress\\\\.NET Applications\\\\IXTextIndexBuilder\\\\IXTextIndexBuilder\\\\bin\\\\Debug\\\\"

EXPECTED RESULT:

"C:\\\\Mainline Code\\\\IxExpress\\\\.NET Applications\\\\IXTextIndexBuilder\\\\IXTextIndexBuilder\\\\bin"

Answer 1

You can use something like the following to get the parent of a given directory:

        string dirName = AppDomain.CurrentDomain.BaseDirectory; // Starting Dir
        FileInfo fileInfo = new FileInfo(dirName);
        DirectoryInfo parentDir = fileInfo.Directory.Parent;
        string parentDirName = parentDir.FullName; // Parent of Starting Dir

Answer 2

使用以下代码段：

string path = (new FileInfo(AppDomain.CurrentDomain.BaseDirectory)).Directory.Parent.FullName;

Answer 3

Directory.GetParent(AppDomain.CurrentDomain.BaseDirectory).Parent.FullName
