Delhi Chapter: Pre-Conference Full Day Hands-On Workshop on Node. Net, uploading a physical file using the file upload control is very easy. Also, during the upload process, we will copy the file from its original location to a specified location. Then we can also download that file from that specified location. For the preceding purposes, we create two projects in Visual Studio.
Now we add an Angular. This file can be easily downloaded from the Nuget Gallery or from the Angular website. Now our objective is, after selecting the file, it will automatically read the file and show the file size in the page. For this purpose, we called the onchange event of the file upload control and written the following code. This function takes the instance of the control as an argument and updates the scope with the file detail information, such as file name, file size in bytes and so on.
Now our next objective is to upload the file using the Web API so that this specific file can be copied and saved in a specific location. We need to click on this button for uploading. Here I am using Temporary Internet Files folder for the location. Now write the following code first into the fileupload. Now for the Web API code. Now our file upload part is complete.
Now, if we run the project and select a file and click on the upload button it will display the file location in an alert box. We can check that the file is physically there. Now we will write the code for this download button in the fileuploader. In the preceding code, we first created the file extension from the file name and then set the file MIME type depending on the file extension. The file download method is as in the following.
The following is the complete code of the Fileuploader. There is one thing we need to remember. In a normal scenario, Visual Studio or ASP. NET allows us to upload a file of a maximum size of 4 MB.
If we want to upload a larger file then we need to change the web. Now, our task is complete and we will run the project. The following is the final output. Bulletproof Disposable Types In .
