如何仅查找目录AppData \\\\ Local的一部分？

Question

I have this:

private void SearchForDoc()
{
    string t = Path.GetDirectoryName(Application.LocalUserAppDataPath);
}

Then the variable t contain:

C:\\Users\\bout0_000\\AppData\\Local\\Diagnostic_Tool_Blue_Screen\\Diagnostic Tool Blue Screen

I want that t will contain only the C:\\\\Users\\\\bout0_000\\\\ and if someone else username is testme so the the variable t will be: C:\\\\Users\\\\testme\\\\

And not all this long path.

Answer 1

Environment.GetEnvironmentVariable("UserProfile");

如果您当前的用户是'toto'，则此命令将返回'C：\\ Users \\ toto'

Answer 2

我认为这会做

Environment.GetFolderPath(Environment.SpecialFolder.UserProfile);

Answer 3

As Ulaga said you could use Environment.GetFolderPath(Environment.SpecialFolder.UserProfile); to get the users directory, or you could just cut off after the first 3 folders.

string t = Path.GetDirectoryName(Application.LocalUserAppDataPath);
t = String.Join(@"\", t.Split('\\').ToList().Take(3).ToArray());
