The following code examples show how to use `AddTagsToStream`.

------
#### [ .NET ]

**Amazon SDK for .NET**  
 There's more on GitHub. Find the complete example and learn how to set up and run in the [Amazon Code Examples Repository](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/dotnetv3/Kinesis#code-examples). 

```
    using System;
    using System.Collections.Generic;
    using System.Threading.Tasks;
    using Amazon.Kinesis;
    using Amazon.Kinesis.Model;

    /// <summary>

                Tags = tags,
            };

            var response = await client.AddTagsToStreamAsync(request);

#### [ CLI ]

**Amazon CLI**  
**To add tags to a data stream**  
The following `add-tags-to-stream` example assigns a tag with the key `samplekey` and value `example` to the specified stream.  

```
aws kinesis add-tags-to-stream \
    --stream-name {{samplestream}} \
    --tags {{samplekey=example}}
```
This command produces no output.
