如何在不等待 C# 的情况下取消分配 Azure 虚拟机

Question

I am using the C# SDK for Microsoft Azure to stop (deallocate) a virtual machine. I am trying to use either Microsoft.Azure.Management.Compute.Fluent.IVirtualMachine.Deallocate or Microsoft.Azure.Management.Compute.IVirtualMachine.DeallocateWithHttpMessagesAsync . Both seem to wait for the virtual machine to complete the deallocation process.

I want to deallocate virtual machines without blocking to wait for the deallocate to complete.

I notice in the Azure CLI documentation that there is a --no-wait option.

Source: https://docs.microsoft.com/en-us/cli/azure/vm?view=azure-cli-latest#az_vm_deallocate

How can I achieve this using the C# SDK for Azure?

Answer 1

I found my answer.

I can use Microsoft.Azure.Management.Compute.IVirtualMachine.BeginDeallocateWithHttpMessagesAsync to initiate the deallocation process. The method returns immediately without waiting for the VM to actually finish the deallocation process.

Answer 2

Had troubles finding out how to use accepted answer, so wanted to share the snippet.

using Microsoft.Azure.Management.Compute.Fluent;
using Microsoft.Azure.Management.ResourceManager.Fluent;
using Microsoft.Azure.Management.ResourceManager.Fluent.Core;


....


async Task DeallocateAzureVirtualMachine()
{
    // there are other ways to obtain credentials as well. 
    // this one is related to an App registration
    var credentials = SdkContext.AzureCredentialsFactory
                    .FromServicePrincipal("clientId", "secretKey", "tenantId",
                    AzureEnvironment.AzureGlobalCloud);

    var restClient = RestClient
                        .Configure()
                        .WithEnvironment(AzureEnvironment.AzureGlobalCloud)
                        .WithLogLevel(HttpLoggingDelegatingHandler.Level.Basic)
                        .WithCredentials(credentials)
                        .Build();

    using (var computeManagementClient = new ComputeManagementClient(restClient))
    {
        await computeManagementClient.VirtualMachines
            .BeginDeallocateWithHttpMessagesAsync("resource-group-name", "vm-name");
    }
}
