Introduction
ASP.NET is a popular programming language used for developing web applications. In this article, we will explore how to upload large files in an ASP.NET Core web application.
Step 1: Configure the Application
Before we can start uploading large files, we need to configure our ASP.NET Core web application to allow for larger file sizes. By default, ASP.NET Core has a maximum file upload size limit of 30MB. To increase this limit, we need to modify the application's configuration.
Step 2: Create the File Upload Form
Next, we need to create a form in our ASP.NET Core web application that allows users to select and upload large files. We can use the HTML element to create a file input field.
Step 3: Handle the File Upload
Once the user selects a file and clicks the “Upload” button, we need to handle the file upload in our ASP.NET Core web application. We can do this by creating a controller action that receives the uploaded file.
Step 4: Handle Large File Uploads
By default, ASP.NET Core buffers the entire file into memory before processing it. This can cause performance issues when uploading large files. To handle large file uploads efficiently, we can use the Stream class to read the file in chunks.
Conclusion
In this article, we have learned how to upload large files in an ASP.NET Core web application. By increasing the maximum file size limit, creating a file upload form, and handling the file upload efficiently, we can provide a seamless experience for users uploading large files.
