Properties

NameTypeDescription
Public Property ContentLength System.Int64 Inherited from Amazon.Runtime.AmazonWebServiceResponse.
Public Property HttpStatusCode System.Net.HttpStatusCode Inherited from Amazon.Runtime.AmazonWebServiceResponse.
Public Property NextToken System.String

Gets and sets the property NextToken.

The token to include in another request to get the next page of items. This value is null when there are no more items to return.

Public Property Reservations System.Collections.Generic.List<Amazon.EC2.Model.Reservation>

Gets and sets the property Reservations.

Information about the reservations.

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.

Public Property ResponseMetadata Amazon.Runtime.ResponseMetadata Inherited from Amazon.Runtime.AmazonWebServiceResponse.
