Container for the parameters to the CreateTags operation. Adds or overwrites only the specified tags for the specified Amazon EC2 resource or resources. When you specify an existing tag key, the value is overwritten with the new value. Each resource can have a maximum of 50 tags. Each tag consists of a key and optional value. Tag keys must be unique per resource.

For more information about tags, see Tag your Amazon EC2 resources in the Amazon Elastic Compute Cloud User Guide. For more information about creating IAM policies that control users' access to resources based on tags, see Supported resource-level permissions for Amazon EC2 API actions in the Amazon Elastic Compute Cloud User Guide.

The CreateTagsRequest type exposes the following members


Public Method CreateTagsRequest()

Empty constructor used to set properties independently even when a simple constructor is available

Public Method CreateTagsRequest(List<String>, List<Tag>)

Instantiates CreateTagsRequest with the parameterized properties


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

Gets and sets the property Resources.

The IDs of the resources, separated by spaces.

Constraints: Up to 1000 resource IDs. We recommend breaking up this request into smaller batches.

Public Property Tags System.Collections.Generic.List<Amazon.EC2.Model.Tag>

Gets and sets the property Tags.

The tags. The value parameter is required, but if you don't want the tag to have a value, specify the parameter with no value, and we set the value to an empty string.


This example adds the tag Stack=production to the specified image, or overwrites an existing tag for the AMI where the tag key is Stack.

To add a tag to a resource

var client = new AmazonEC2Client();
var response = client.CreateTags(new CreateTagsRequest 
    Resources = new List<string> {
    Tags = new List<Tag> {
        new Tag {
            Key = "Stack",
            Value = "production"
