610 is a column value named by studentid in my student details table.

If I am select any student id like 610 or 12 whatever it is.

The student files are saved in my parent folder Profiledocs. like this

\Profiledocs\610\myfile.txt
\Profiledocs\121\myfile1.txt
\Profiledocs\321\myfile2.txt

Now what I am make to delete the sub folders and files in my parent folder Profiledocs

`Directory.Delete(@"D:\Vinayak\Student\Profiledocs\610", true);`? - remove `\610` folder with all its content? — Dmitry Bychenko, Nov 14 '18 at 06:52

so you want to delete the entire 610 folder basically, not just that file? — Kush, Nov 14 '18 at 06:56

You can use below method to delete sub folder and its content by passing studentId as parameter.

private static void DeleteSubFolderAndContent(int studentId)
{
    string path = Path.Combine(@"D:\Vinayak\Student\Profiledocs", studentId.ToString());   
    Directory.Delete(path, true);
}

You can use above function like

static void Main(string[] args)
{
    DeleteSubFolderAndContent(610); // <= "610" comes from database

    Console.WriteLine("Sub Folder and Its Content Deleted Successfully");
    Console.ReadLine();
}

Note: Make sure that your upload folder have full access control to read and write.

@DmitryBychenko, thanks for improvement, answer updated :) – er-sho Nov 14 '18 at 07:27 — er-sho, Nov 14 '18 at 07:27

So, you have the full file path, and you wish to delete its current directory. First you need to get the directory path.

fileDirectory = System.IO.Path.GetDirectoryName(filename)

This piece of code below will delete all folders and files in your current directory.

System.IO.DirectoryInfo di = new DirectoryInfo(fileDirectory);

foreach (FileInfo file in di.GetFiles())
{
    file.Delete(); 
}
foreach (DirectoryInfo dir in di.GetDirectories())
{
    dir.Delete(true); 
}

If "you wish to delete its current directory", why the `foreach` loops and not just `new DirectoryInfo(fileDirectory).Delete(true);`? — Rufus L, Nov 14 '18 at 07:05
