[Apache Arrow for C# .NET](https://github.com/apache/arrow/blob/main/csharp/README.md) integrates with C# .NET scripts and applications to query data stored in InfluxDB.

For more information, see the [C# client example on GitHub](https://github.com/apache/arrow/tree/main/csharp/examples/FlightClientExample).

> [!Note]
> #### Use InfluxDB 3 client libraries
> 
> We recommend using the [`influxdb3-csharp` C# client library](/influxdb3/version/reference/client-libraries/v3/csharp/) for integrating InfluxDB 3 with your C# application code.
> 
> [InfluxDB 3 client libraries](/influxdb3/version/reference/client-libraries/v3/) wrap Apache Arrow Flight clients
> and provide convenient methods for [writing](/influxdb3/version/write-data/api-client-libraries/), [querying](/influxdb3/version/query-data/execute-queries/), and processing data stored in {{% product-name %}}.
> Client libraries can query using SQL or InfluxQL.
