To create the path, the code uses the current website path as returned by the Server. MapPath method , the images folder name, the name that the user has provided, and ". To delete the file, the code calls the File. Delete method, passing it the full path that you just constructed. At the end of the markup, code displays a confirmation message that the file was deleted. Enter the name of the file to delete and then click Submit. If the file was deleted, the name of the file is displayed at the bottom of the page.

The FileUpload helper lets users upload files to your website. The procedure below shows you how to let users upload a single file. Add the ASP. The body portion of the page uses the FileUpload helper to create the upload box and buttons that you're probably familiar with:.

The properties that you set for the FileUpload helper specify that you want a single box for the file to upload and that you want the submit button to read Upload. You'll add more boxes later in the article.

When the user clicks Upload , the code at the top of the page gets the file and saves it. The Request object that you normally use to get values from form fields also has a Files array that contains the file or files that have been uploaded.

You can get individual files out of specific positions in the array — for example, to get the first uploaded file, you get Request.

Files[0] , to get the second file, you get Request. Files[1] , and so on. Remember that in programming, counting usually starts at zero. When you fetch an uploaded file, you put it in a variable here, uploadedFile so that you can manipulate it. To determine the name of the uploaded file, you just get its FileName property. However, when the user uploads a file, FileName contains the user's original name, which includes the entire path.

It might look like this:. You don't want all that path information, though, because that's the path on the user's computer, not for your server. You just want the actual file name Sample. You can strip out just the file from a path by using the Path.

GetFileName method, like this:. The Path object is a utility that has a number of methods like this that you can use to strip paths, combine paths, and so on.

Once you've gotten the name of the uploaded file, you can build a new path for where you want to store the uploaded file in your website. In this case, you combine Server. You can then call the uploaded file's SaveAs method to actually save the file. In the previous example, you let users upload one file. But you can use the FileUpload helper to upload more than one file at a time. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Here we'll explore which upload approach is better to use when, but before that let's take a look at ASP. During the file upload process, only two parts of the MVC model interact with each other — a view and a controller.

You can configure file upload settings by specifying appropriate attributes in the web. Note: Avoid specifying "unlimited" very large values there. Specifying realistic limits, you can improve the performance of your server or reduce the risk of DoS attacks. Firstly, we consider the view.

The view code with razor syntax may look as follows:. After a user submits the form, the View sends posted data to the Action method of the Controller that handles file upload. Otherwise it won't get the uploaded file. The action model looks like this:.
