使用 AWS CloudFormation 列出 AWS 资源

此示例向您展示如何使用AWS SDK for .NET列出 AWS CloudFormation 堆栈中的资源。该示例使用低级别 API。该应用程序不带任何参数，只是收集用户凭证可以访问的所有堆栈的信息，然后显示有关这些堆栈的信息。

using System;
using System.Threading.Tasks;
using Amazon.CloudFormation;
using Amazon.CloudFormation.Model;

namespace CFNListResources
{
  class Program
  {
    static async Task Main(string[] args)
    {
      // Create the CloudFormation client
      var cfnClient = new AmazonCloudFormationClient();

      // List the resources for each stack
      await ListResources(cfnClient, await cfnClient.DescribeStacksAsync());
    }

    //
    // Method to list stack resources and other information
    private static async Task ListResources(
      IAmazonCloudFormation cfnClient, DescribeStacksResponse responseDescribeStacks)
    {
      Console.WriteLine("Getting CloudFormation stack information...");

      foreach (Stack stack in responseDescribeStacks.Stacks)
      {
        // Basic information for each stack
        Console.WriteLine("\n------------------------------------------------");
        Console.WriteLine($"\nStack: {stack.StackName}");
        Console.WriteLine($"  Status: {stack.StackStatus.Value}");
        Console.WriteLine($"  Created: {stack.CreationTime}");

        // The tags of each stack (etc.)
        if(stack.Tags.Count > 0)
        {
          Console.WriteLine("  Tags:");
          foreach (Tag tag in stack.Tags)
            Console.WriteLine($"    {tag.Key}, {tag.Value}");
        }

        // The resources of each stack
        DescribeStackResourcesResponse responseDescribeResources =
          await cfnClient.DescribeStackResourcesAsync(new DescribeStackResourcesRequest{
            StackName = stack.StackName});
        if(responseDescribeResources.StackResources.Count > 0)
        {
          Console.WriteLine("  Resources:");
          foreach(StackResource resource in responseDescribeResources.StackResources)
            Console.WriteLine($"    {resource.LogicalResourceId}: {resource.ResourceStatus}");
        }
      }
      Console.WriteLine("\n------------------------------------------------");
    }
  }
}
