在AWS .NET SDK中列出实例

Question

我正在编写代码,使用.net SDK for AWS列出实例ID和实例类型.我知道我需要使用DescribeInstancesRequest类.我还认为我需要使用ArrayList来存储字符串输出,并使用foreach循环来获取所有实例.我只是把它放在一起很麻烦!像在控制台中列出实例ID这样简单的事情对我来说将是一个很大的帮助.

有没有人做过类似的事情？

我正朝着到达我需要的地方迈出一小步.我是.net AWS SDK的新手,所以这是一个非常缓慢的过程.下面的代码计算我拥有的实例数并返回它.现在我只需要弄清楚如何列出实际的实例ID.

有任何想法吗？

AmazonEC2 ec2 = new AmazonEC2Client();

DescribeInstancesRequest request = new DescribeInstancesRequest();
DescribeInstancesResponse res = ec2.DescribeInstances(request);

Console.WriteLine(res.DescribeInstancesResult.Reservation.Count);
Console.Read();

不要打败死马,但对于我的任务,我必须在HTML表格中打印出实例ID和实例类型.如果您想在网站上托管它,这可能很有用.你需要做的就是改变路径StreamWriter.这是我的草率但成品.

  AmazonEC2 ec2 = new AmazonEC2Client();
        DescribeInstancesRequest req = new DescribeInstancesRequest();
        List<Amazon.EC2.Model.Reservation> result = ec2.DescribeInstances(req).DescribeInstancesResult.Reservation;
        using (StreamWriter writer = new StreamWriter(@"C:\Users\Ethan\Desktop\InstanceOutput.html"))                  //change this output to a local address if testing the code
        {
            writer.Write("<table border=1><tbody><tr><th>Instance ID</th><th>Instance Type</th></tr>");
            foreach (Amazon.EC2.Model.Reservation reservation in result)
            {
                foreach (Amazon.EC2.Model.RunningInstance runningInstance in reservation.RunningInstance)
                {
                    writer.WriteLine("<tr><td>" + runningInstance.InstanceId + "</td><td>" + runningInstance.InstanceType + "</td></tr>");
                }
            }
            writer.Write("</tbody></table>");
        }

所以请记住,我对此不熟悉,有人可能会想出一个更清洁,更有效,更好的答案.这就是我在控制台中打印实例ID和实例类型的方法.

AmazonEC2 ec2 = new AmazonEC2Client();
DescribeInstancesRequest req = new DescribeInstancesRequest();
List<Amazon.EC2.Model.Reservation> result = ec2.DescribeInstances(req).DescribeInstancesResult.Reservation;

        foreach (Amazon.EC2.Model.Reservation reservation in result)
        {
            foreach (Amazon.EC2.Model.RunningInstance runningInstance in reservation.RunningInstance)
            {
                Console.WriteLine(runningInstance.InstanceId);
                Console.WriteLine(runningInstance.InstanceType);
            }
        }
