# bamcis.io PrestoClient - A Prestodb .NET Client

## Usage

### Basic Example 1

This demonstrates creating a new client config, initializing an IPrestoClient, and executing a simple query. The

returned data can be formatted in CSV or JSON. Additionally, all of the raw data is returned from the server

in case the deserialization process fails in .NET, the user can still access and manipulate the returned data.

```csharp

PrestoClientSessionConfig config = new PrestoClientSessionConfig("hive", "cars")

{

   Host = "localhost",

   Port = 8080

};

IPrestoClient client = new PrestodbClient(config);

ExecuteQueryV1Request request = new ExecuteQueryV1Request("select * from tracklets limit 5;");

ExecuteQueryV1Response queryResponse = await client.ExecuteQueryV1(request);

Console.WriteLine(String.Join("\n", queryResponse.DataToCsv()));

Console.WriteLine("-------------------------------------------------------------------");

Console.WriteLine(String.Join("\n", queryResponse.DataToJson()));

```
