Before getting started

Skill Level: Beginner

Assumptions:

1. You have completed Part 1 of Managing Amazon AWS with C# – EC2

Additional Information: I sometimes cover small sub-topics in a post. Along with AWS, you will also be exposed to:

• .NET Core 2.0 – If you use .NET Framework, the steps will be slightly different, but as this is a beginner level tutorial, it should be simple.
• Rhyous.SimpleArgs

Step 1 – Edit InstanceManager.cs file

We’ve created InstanceManager.cs in Part 1. Let’s edit it.

1. Add a method to delete the key pair.

        public static async Task DeleteKeyPair(AmazonEC2Client ec2Client, string keyName)
        {
            await ec2Client.DeleteKeyPairAsync(new DeleteKeyPairRequest { KeyName = keyName });
        }

Step 5 – Configure command line Arguments.

We already have an Actions arguments to edit.

1. Add DeleteKeyPair as a valid action to the Action argument.

                . . .
                new Argument
                {
                    Name = "Action",
                    ShortName = "a",
                    Description = "The action to run.",
                    Example = "{name}=default",
                    DefaultValue = "Default",
                    AllowedValues = new ObservableCollection<string>
                    {
                        "CreateKeyPair",
                        "DeleteKeyPair"
                    },
                    IsRequired = true,
                    Action = (value) =>
                    {
                        Console.WriteLine(value);
                    }
                },
                . . .
