asp net core web api upload file to database

Follow this tutorial to learn how to implement file upload with data using ASP.NET Core Web API. The following example demonstrates how to upload files in a Blazor Server app with upload progress displayed to the user. The web application takes the file to process then if required it will perform some validations on the file and finally will store this file in the storage configured in the system for saving files i.e. Create a CancellationTokenSource for the InputFile component. .NET C# Your request cURL should look like the below: And in Postman request editor you can do it as the below: Choose POST, enter the endpoint URL, and from Body tab, choose form-data, and then start adding the Key, Value pairs as the below: Note related to Image Key, to make its type as File, you have to hover your mouse on field to bring up the small arrow from which you will choose File instead of text: And checking the database table, you can see the record created under the Post table , with the Imagepath set to the physical location of the saved image: And below is the folder structure, see how the folders are appearing inside the wwwroot folder: If we try to post some large file that exceeds the set request size which is 5 MB in our tutorial, it will throw a 400 bad request as mentioned previously in this tutorial, see the below screenshot for the repsonse details: So in this tutorial we learned how to implement a file upload with data using ASP.NET Core Web API. ASP.NET Core supports uploading one or more files using buffered model binding for smaller files and unbuffered streaming for larger files. For example, don't copy all of the file's bytes into a MemoryStream or read the entire stream into a byte array all at once. These steps are usually performed in conjunction with a database record that indicates the scanning status of a file.

The topic demonstrates UploadFromFileAsync, but UploadFromStreamAsync can be used to save a FileStream to blob storage when working with a Stream. Creating ASP.NET Core Application It doesn't matter which framework you use in the client-side, as far it's a JS Framework code implementation will be the same with little basic knowledge.Although we will be uploading files synchronously in .NET core. Cloud Storage Let's add a new Action Method (POST) named UploadToDatabase that, similar to the previous method, takes in a list of iformfile and a description. Step-by-step Implementation Step 1 Create a new .NET Core Web API Step 2 Install the following NuGet Packages Step 3 Create the following file entities FileDetails.cs This article explains how to upload files in Blazor with the InputFile component. Required fields are marked *. This service will be used in the controller to save the file posted as a stream. The entire file is read into an IFormFile. Azure Storage The contents of the file in the IFormFile are accessed using the Stream. For the demonstration of how to perform file upload in ASP.NET Core, we will take the following approach, Create a new project of type ASP.NET Core MVC as per the screenshots shown below with the name of the project as ProCodeGuide.Samples.FileUpload, We will be using this project to demonstrate both types i.e. The FileUpload is used in the Razor Pages form: When the form is POSTed to the server, copy the IFormFile to a stream and save it as a byte array in the database. The database limits may put some restrictions on the maximum size of the file allowed for storage. Foremost, we check if ModelState is valid or not. InputFileChangeEventArgs.GetMultipleFiles allows reading multiple files. Also confirm that the upload naming in form data matches the app's naming. Using a Counter to Select Range, Delete, and Shift Row Up. Finally, we managed to run some tests on localhost using Postman by mimicking a request with POST body passed as form-data in key-value pairs. The following example demonstrates uploading files to a web API controller in the Server app of a hosted Blazor WebAssembly solution. The attribute uses ASP.NET Core's built-in antiforgery support to set a cookie with a request token: The DisableFormValueModelBindingAttribute is used to disable model binding: In the sample app, GenerateAntiforgeryTokenCookieAttribute and DisableFormValueModelBindingAttribute are applied as filters to the page application models of /StreamedSingleFileUploadDb and /StreamedSingleFileUploadPhysical in Startup.ConfigureServices using Razor Pages conventions: Since model binding doesn't read the form, parameters that are bound from the form don't bind (query, route, and header continue to work). In a Razor pages app or an MVC app, apply the filter to the page handler class or action method: The RequestSizeLimitAttribute can also be applied using the @attribute Razor directive: Other Kestrel limits may apply for apps hosted by Kestrel: The default request limit (maxAllowedContentLength) is 30,000,000 bytes, which is approximately 28.6 MB. The app can safely process the files from the external service on demand. By default, the user selects single files. Make sure you are using the latest version of Visual Studio alongside the latest stable version of .NET which is .NET 6, and for this tutorial we will require to use SQL Server Express, SQL Server Management Studio and for testing we will use Postman.

The entire file is read into an IFormFile, which is a C# representation of the file used to process or save the file. After the multipart sections are read, the contents of the KeyValueAccumulator are used to bind the form data to a model type. FormData provides a way to easily construct a set of key/value pairs representing form fields and their values, which can then be easily sent using the XMLHttpRequest.send () method. :::no-loc text="Error: Connection disconnected with error 'Error: Server returned an error on close: Connection closed with an error.'.

The Entity Model that I have created is this: Only selected types of files(pdf, png, jpg, jpeg) can be uploaded. Because the action method processes the uploaded data directly, form model binding is disabled by another custom filter. Many implementations must include a check that the file exists; otherwise, the file is overwritten by a file of the same name. If you are passing the file back to your controller using HttpPostedFileBase, you can adapt the following code to suit your needs. For more information, see Upload files in ASP.NET Core.
