| How to store uploaded files into folders organized by year, month, and day in ASP.NET web form? |
protected void btnUpload_Click(object sender, EventArgs e) { // Get the base directory path where you want to store the files string baseDirectory = Server.MapPath("~/uploads/"); // Get the current date DateTime currentDate = DateTime.Now; // Get the year, month, and day as numeric values string year = currentDate.Year.ToString(); string month = currentDate.Month.ToString(); string day = currentDate.Day.ToString(); // Create the year folder path by combining the base directory and the year string yearFolderPath = Path.Combine(baseDirectory, year); // Create the month folder path by combining the year folder path and the month string monthFolderPath = Path.Combine(yearFolderPath, month); // Create the day folder path by combining the month folder path and the day string dayFolderPath = Path.Combine(monthFolderPath, day); // Create the year folder if it doesn't exist if (!Directory.Exists(yearFolderPath)) { Directory.CreateDirectory(yearFolderPath); } // Create the month folder if it doesn't exist if (!Directory.Exists(monthFolderPath)) { Directory.CreateDirectory(monthFolderPath); } // Create the day folder if it doesn't exist if (!Directory.Exists(dayFolderPath)) { Directory.CreateDirectory(dayFolderPath); } // Get the uploaded file if (fileUpload.HasFile) { // Get the file extension string fileExtension = Path.GetExtension(fileUpload.FileName); // Generate a unique file name using a combination of current date and time string fileName = DateTime.Now.ToString("yyyyMMddHHmmss") + fileExtension; // Set the file path by combining the day folder path and the generated file name string filePath = Path.Combine(dayFolderPath, fileName); // Save the file to the specified path fileUpload.SaveAs(filePath); // Display a success message lblMessage.Text = "File uploaded successfully!"; } else { // Display an error message if no file is selected lblMessage.Text = "Please select a file to upload!"; } }

Hint: The code uses the DateTime.Now function to get the current date. It then extracts the year, month, and day as numeric values. The code creates a folder structure using these values, starting with a base directory path. It checks if the year, month, and day folders already exist and creates them if they don't. The uploaded file is saved into the corresponding day folder with a unique file name generated using the current date and time.The code uses the DateTime.Now function to get the current date.
