How to Add Tags to Azure Resource from a C# - Web Application

Question

How can I add Tags to an azure resource using C# Code in my ASP.NET Application. I am trying to create an azure tag management portal.

I found this question but it is about adding a tag to a resource group . Also that Library seems deprecated. If any one knows how to attach a tag to a Resource, Please help.

Note: (i)I have tried the Azure ServiceManagement API but I see there is no API support for attaching a tag to a resource. (ii) Will powershell Cmdlets a viable option if nothing else works?

Answer 1

Follow this link to create client application in AD and service principle. Make note of tenantId, ClientId and ClientKey

https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-create-service-principal-portal

Find the resource, add / update tags and patch it.

var serviceCreds = await ApplicationTokenProvider.LoginSilentAsync(tenantId, clientId, clientKey);
var resourceClient = new ResourceManagementClient(serviceCreds);
resourceClient.SubscriptionId = subscriptionId;

GenericResource genericResource = resourceClient.Resources.Get("some-resource-group", "Microsoft.DocumentDB", "", "databaseAccounts", "some-resource", "2016-03-31");

genericResource.Tags.Add("Version", "1.0");

resourceClient.Resources.CreateOrUpdate("some-resource-group", "Microsoft.DocumentDB", "", "databaseAccounts", "some-resource", "2016-03-31", genericResource);

PowerShell could easily do this, you can use the command below:

PS C:\> Set-AzureRmResource -Tag @( @{ Name="tag_name"; Value="tag_value" }) -ResourceId <resource_id>

Check this article for details.

If anyone interested in a way to try out through REST API, I found this after spying on powershell bound traffic using Fiddler. Note the tag as json-payload.
