有没有办法获取使用 Azure SDK for .NET 部署的 ARM 模板的输出参数？

Question

我想使用 Azure SDK for .NET 部署 ARM 模板，然后以 JSON 格式获取输出内容（在 ARM 模板中定义），以便在其他地方使用它。

我使用 ResourcesManagementClient.Deployments 来部署我的 ARM 模板，问题是我不知道如何 return 我的输出参数。

代码看起来像这样：

            var deploymentOptions = new Deployment(new DeploymentProperties(DeploymentMode.Incremental)
            {
                Template = <<TEMPALTE>>,
                Parameters = <<PARAMETERS>>,
            });
       deploymentOptions.Location = <<LOCATION>>;
       await deploymentClient.StartCreateOrUpdateAtSubscriptionScopeAsync(<<DEPLOYMENT NAME>>, deploymentOptions);

您可以使用以下代码从部署中获取输出变量：

// Requires the following Azure NuGet packages and related dependencies:
// package id="Microsoft.Azure.Management.Authorization" version="2.0.0"
// package id="Microsoft.Azure.Management.ResourceManager" version="1.4.0-preview"
// package id="Microsoft.Rest.ClientRuntime.Azure.Authentication" version="2.2.8-preview"
  
using Microsoft.Azure.Management.ResourceManager;
using Microsoft.Azure.Management.ResourceManager.Models;
using Microsoft.Rest.Azure.Authentication;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using System;
using System.IO;

                var resourceGroup = new ResourceGroup();
                resourceGroup.Location = resourceGroupLocation;
                resourceManagementClient.ResourceGroups.CreateOrUpdate(resourceGroupName, resourceGroup);

            var deployment = new Deployment();

            deployment.Properties = new DeploymentProperties
            {

                Template = templateFileContents,

            };

            var deploymentResult = resourceManagementClient.Deployments.CreateOrUpdate(resourceGroupName, deploymentName, deployment);
            Console.WriteLine(string.Format("Deployment status: {0}", deploymentResult.Properties.Outputs));
        }
    }
}

resourceManagementClient.Deployments.CreateOrUpdate 将 return DeploymentPropertiesExtended Class，其中包含多个数据，包括您的部署的 Output。
