How to delete subdirectories

Question

Hello!

Lets say a have some path: C:\Temp\TestFolder1\TestFolder2

And I have some template: C:\Temp

So i want to write function that will delete all subdirectories by template

void DeleteSubdirectories(string tlt, string path) {}

If I call this function with given parameters

DeleteSubdirectories("C:\Temp", "C:\Temp\TestFolder1\TestFolder2");

It must delete TestFolder1\TestFolder2 subdirectories from 'C:\Temp

What is the best way to write this function?

Answer 1

System.IO.Directory.Delete("Path", true);

Answer 2

Just use Directory.Delete - the overload I linked has a boolean value that indicates if subdirectories should also be deleted.

Answer 3

If you desire to delecte "C:\Temp" too, use this:

System.IO.Directory.Delete(@"C:\Temp", true);

If you just want to delete the sub directories use this:

        foreach (var subDir in new DirectoryInfo(@"C:\Temp").GetDirectories()) {
            subDir.Delete(true);
        }

What you're describing sounds wierd, but try this:

using System;
using System.IO;

static void DeleteSubDirectories(string rootDir, string childPath)
{
    string fullPath = Path.Combine(rootDir, childPath);

    Directory.Delete(fullPath);

    string nextPath = Path.GetDirectoryName(fullPath);

    while (nextPath != rootDir)
    {
        Directory.Delete(nextPath);
        nextPath = Path.GetDirectoryName(nextPath);
    }
}

Use it like:

DeleteSubdirectories("C:\Temp", "TestFolder1\TestFolder2");

Obviously, you'll have to implement the exception handling.
