#### [ .NET ]

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

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

    /// <summary>
    /// Shows how to deregister a consumer from an Amazon Kinesis stream.

            var response = await client.DeregisterStreamConsumerAsync(request);

#### [ CLI ]

**AWS CLI**  
**To deregister a data stream consumer**  
The following `deregister-stream-consumer` example deregisters the specified consumer from the specified data stream.  

```
aws kinesis deregister-stream-consumer \
    --stream-arn arn:aws:kinesis:us-west-2:123456789012:stream/samplestream \
    --consumer-name KinesisConsumerApplication
```
This command produces no output.
