C# - How to Delete all Files in Folders and SubFolders in C#, VB.NET

Introduction:

Here I will explain how to delete all files in folders and subfolders in asp.net using C# and VB.NET.

Description:

In previous articles I explained Create or Delete directory/folder in c#, Delete files from uploaded folder in asp.net, jQuery Dropdown Menu example, start and stop timer example in JavaScript, Asp.net Interview questions and many articles relating to Gridview, SQL, jQuery,asp.net, C#,VB.NET. Now I will explain how to delete files in folders and subfolders in asp.net using C# and VB.NET.

To delete files in folders and subfolders first we need to add namespace using System.IO

Once we add namespace need to write the code like as shown below

C# Code

// Delete direcoty or folder protected void btnDelete_Click(object sender, EventArgs e) { string strpath = @"D:\" + txtdltName.Text; if (Directory.Exists(strpath)) { RemoveDirectories(strpath); } } private void RemoveDirectories(string strpath) { //This condition is used to delete all files from the Directory foreach (string file in Directory.GetFiles(strpath)) { File.Delete(file); } //This condition is used to check all child Directories and delete files foreach (string subfolder in Directory.GetDirectories(strpath)) { RemoveDirectories(subfolder); } Directory.Delete(strpath); }

VB.NET Code

' Delete direcoty or folder Protected Sub btnDelete_Click(sender As Object, e As EventArgs) Dim strpath As String = "D:\" + txtdltName.Text If Directory.Exists(strpath) Then RemoveDirectories(strpath) End If End Sub Private Sub RemoveDirectories(strpath As String) 'This condition is used to delete all files from the Directory For Each file1 As String In Directory.GetFiles(strpath) File.Delete(file1) Next 'This condition is used to check all child Directories and delete files For Each subfolder As String In Directory.GetDirectories(strpath) RemoveDirectories(subfolder) Next Directory.Delete(strpath) lblResult.Text = "Directory deleted" End Sub
