The samples in this section have not been verified against the latest version of Umbraco.
Instead, we recommend using the Media Picker for uploading files to your Umbraco website.
See the example below to see how a value can be added or changed programmatically. To update a value of this property editor you need the Content Service and the Media Service.
The example below demonstrates how to add values programmatically using a Razor view. However, this is used for illustrative purposes only and is not the recommended method for production environments.
@using Umbraco.Cms.Core.IO@using Umbraco.Cms.Core.Serialization@using Umbraco.Cms.Core.Strings@inject MediaFileManager _mediaFileManager;@inject IShortStringHelper _shortStringHelper;@inject IContentTypeBaseServiceProvider _contentTypeBaseServiceProvider;@inject IContentService Services;@inject IJsonSerializer _serializer;@inject MediaUrlGeneratorCollection _mediaUrlGeneratorCollection;@{ // Get access to ContentServicevar contentService = Services; // Get access to MediaService var mediaService = MediaService; // Create a variable for the GUID of the parent where you want to add a child itemvar guid =Guid.Parse("32e60db4-1283-4caa-9645-f2153f9888ef"); // Get the page using the GUID you've definedvar content =contentService.GetById(guid); // ID of your page // Create a variable for the file you want to upload, in this case the Our Umbraco logovar imageUrl ="https://our.umbraco.com/assets/images/logo.svg"; // Create a request to get the filevar request =WebRequest.Create(imageUrl);var webResponse =request.GetResponse();var responseStream =webResponse.GetResponseStream(); // Get the file name var lastIndex =imageUrl.LastIndexOf("/",StringComparison.Ordinal) +1;var filename =imageUrl.Substring(lastIndex,imageUrl.Length- lastIndex); // Create a media filevar media =mediaService.CreateMediaWithIdentity("myImage",-1,"File"); media.SetValue(_mediaFileManager, _mediaUrlGeneratorCollection, _shortStringHelper, _contentTypeBaseServiceProvider, Constants.Conventions.Media.File, filename, responseStream);
// Save the created media mediaService.Save(media); // Get the published version of the media (IPublishedContent)var publishedMedia =Umbraco.Media(media.Id); // Set the value of the property with alias 'myFile' content.SetValue("myFile",publishedMedia.Url()); // Save the child itemcontentService.Save(content);}
Although the use of a GUID is preferable, you can also use the numeric ID to get the page:
@{ // Get the page using it's idvar content =contentService.GetById(1234); }
If Modelsbuilder is enabled you can get the alias of the desired property without using a magic string:
The following example uses IPublishedSnapshotAccessor, which is obsolete in Umbraco 15 and will be removed in a future version. For more information, see the Version specific upgrades article.
@inject IPublishedSnapshotAccessor _publishedSnapshotAccessor;@{ // Set the value of the property with alias 'myFile'content.SetValue(Home.GetModelPropertyType(_publishedSnapshotAccessor, x =>x.MyFile).Alias,publishedMedia.Url();}
