FromPort and ToPort

The beginning and end of the port range.This example specifies a single port, 3389, which is

used to communicate with Windows over RDP.

IpRanges

The IP addresses or address ranges, in CIDR notation. For convenience, this example uses

0.0.0.0/0, which authorizes network traffic from all IP addresses.This is acceptable for a short

time in a test environment, but it's unsafe in a production environment.

2. Create and initialize an AuthorizeSecurityGroupIngressRequest object.

var ingressRequest = new AuthorizeSecurityGroupIngressRequest();

ingressRequest.GroupId = mySG.GroupId;

ingressRequest.IpPermissions.Add(ipPermission);

GroupId

The ID of the security group.

IpPermissions

The IpPermission object from step 1.

3. (Optional) You can add additional rules to the IpPermissions collection before going to the next

step.

4. Pass the request object to the AuthorizeSecurityGroupIngress method, which returns an AuthorizeSe-

curityGroupIngressResponse object.

var ingressResponse = ec2Client.AuthorizeSecurityGroupIngress(ingress

Request);

Console.WriteLine("New RDP rule for: " + ipRange);

Create a Key Pair Using the SDK for .NET

You must specify a key pair when you launch an EC2 instance and specify the private key of the key pair

when you connect to the instance.You can create a key pair or use an existing key pair that you've used

when launching other instances. For more information, see Amazon EC2 Key Pairs in the Amazon

Elastic Compute Cloud User Guide for Microsoft Windows.

Enumerating Your Key Pairs

You can enumerate your key pairs and check whether a particular key pair exists.

To enumerate your key pairs

Get the complete list of your key pairs using DescribeKeyPairs with no parameters.The following example

checks each key pair to see whether its name is my-sample-key.

string keyPairName = "my-sample-key";

KeyPairInfo myKeyPair = null;

var dkpRequest = new DescribeKeyPairsRequest();

var dkpResponse = ec2Client.DescribeKeyPairs(dkpRequest);

List<KeyPairInfo> myKeyPairs = dkpResponse.KeyPairs;
