AWS SDK Version 4 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Container for the parameters to the UnassignPrivateNatGatewayAddress operation. Unassigns secondary private IPv4 addresses from a private NAT gateway. You cannot unassign your primary private IP. For more information, see Edit secondary IP address associations in the Amazon VPC User Guide.

While unassigning is in progress, you cannot assign/unassign additional IP addresses while the connections are being drained. You are, however, allowed to delete the NAT gateway.

A private IP address will only be released at the end of MaxDrainDurationSeconds. The private IP addresses stay associated and support the existing connections, but do not support any new connections (new connections are distributed across the remaining assigned private IP address). After the existing connections drain out, the private IP addresses are released.

Properties

NameTypeDescription
Public Property DryRun System.Nullable<System.Boolean>

Gets and sets the property DryRun.

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

Public Property MaxDrainDurationSeconds System.Nullable<System.Int32>

Gets and sets the property MaxDrainDurationSeconds.

The maximum amount of time to wait (in seconds) before forcibly releasing the IP addresses if connections are still in progress. Default value is 350 seconds.

Public Property NatGatewayId System.String

Gets and sets the property NatGatewayId.

The ID of the NAT gateway.

Public Property PrivateIpAddresses System.Collections.Generic.List<System.String>

Gets and sets the property PrivateIpAddresses.

The private IPv4 addresses you want to unassign.

Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.
