将EC2实例启动到vpc并使用公共IP

Question

InstanceNetworkInterfaceSpecification vpc = new InstanceNetworkInterfaceSpecification()
{
SubnetId = "subnet-sadfsadf",
    AssociatePublicIpAddress = true,
    DeleteOnTermination = false

};
List<InstanceNetworkInterfaceSpecification> temp= new List<InstanceNetworkInterfaceSpecification>();
            temp.Add(vpc);

//Create and initialize a RunInstanceRequest
RunInstancesRequest newInstanceRequest = new RunInstancesRequest()
{
   ImageId = appdbAMI,
   InstanceType = appdbType,
   MinCount = 1,
   MaxCount = appdbQuantity,
   KeyName = ec2Key,
   NetworkInsterfaces = temp,
   BlockDeviceMappings = resp.Images[0].BlockDeviceMappings
   //DisableApiTermination = true
};

这不会使用公共IP地址将实例启动到vpc中。这有什么问题？我想在一个vpc中启动一个实例，它也为它分配一个公共IP地址。

正确格式： 我忘了在实例网络接口规范中添加设备索引。 我为安全组创建了字符串列表。 然后，我创建createnetworkinterfacerequest对象并添加子网ID和安全组。 然后创建createnetworkinterfaceresponse对象并创建接口。 接下来，我创建instancenetworkinterfacespecification项并将其添加到列表中。 最后我运行runinstancerequest和bam，它运行了。

List<string> secgrps = new List<string>(new string[] { "sg-2143", "sg-1234" });
CreateNetworkInterfaceRequest cnireq = new CreateNetworkInterfaceRequest()
{ 
SubnetId = "subnet-1234", 
Groups = secgrps 
};
CreateNetworkInterfaceResponse cniresp = ec2Client.CreateNetworkInterface(cnireq);
InstanceNetworkInterfaceSpecification inis = new InstanceNetworkInterfaceSpecification()
{ 
SubnetId = cniresp.NetworkInterface.SubnetId, 
Groups = secgrps, 
AssociatePublicIpAddress = true, 
DeviceIndex=0 
};
List<InstanceNetworkInterfaceSpecification> inisList = new List<InstanceNetworkInterfaceSpecification>();
inisList.Add(inis);

//Create and initialize a RunInstanceRequest
RunInstancesRequest newInstanceRequest = new RunInstancesRequest()
{
    ImageId = appdbAMI,
    InstanceType = appdbType,
    MinCount = 1,
    MaxCount = appdbQuantity,
    KeyName = ec2Key,
    //SecurityGroups = appdbSecurity,
    NetworkInterfaces = inisList,
    BlockDeviceMappings = resp.Images[0].BlockDeviceMappings
    //DisableApiTermination = true
};
