For example a policy to delete the index after X time

I know how to do it in ElasticSearch, for example I can create a policy

PUT _ilm/policy/logs_policy
    {
       "policy": {
        "phases": {
          "delete": {
            "min_age": "2m",
            "actions": {
              "delete": {}
            }
          }
        }
      }
    }

and nex I can link the policy to an index

PUT logs/_settings
    {
      "index": {
        "lifecycle": {
          "name": "logs_policy"
        }
      }
    }

I want to know how to do the same with C# .NET

You could send http request using Elastic.Clients.Elasticsearch

var settings = new ElasticsearchClientSettings(new Uri("http://localhost:9200"))
    .Authentication(new BasicAuthentication("elastic", "your_password")); // Replace with your credentials
var client = new ElasticsearchClient(settings);

// Step 1: Create ILM Policy using Raw API
var policyRequest = new
{
    policy = new
    {
        phases = new
        {
            delete = new
            {
                min_age = "2m",
                actions = new
                {
                    delete = new { }
                }
            }
        }
    }
};

var policyResponse = await client.Transport.RequestAsync<StringResponse>(
    new EndpointPath(Elastic.Transport.HttpMethod.PUT, "_ilm/policy/logs_policy"),  
    PostData.Serializable(policyRequest)
);

if (!policyResponse.ApiCallDetails.HasSuccessfulStatusCode)
{
    Console.WriteLine($"Error creating policy: {policyResponse.Body}");
    return;
}
Console.WriteLine("Policy created successfully.");

// Step 2: Apply ILM Policy to an Index using Raw API
var indexSettingsRequest = new
{
    index = new
    {
        lifecycle = new
        {
            name = "logs_policy"
        }
    }
};

var indexSettingsResponse = await client.Transport.RequestAsync<StringResponse>(
    new EndpointPath(Elastic.Transport.HttpMethod.PUT, "logs/_settings"),
    PostData.Serializable(indexSettingsRequest)
);

if (!indexSettingsResponse.ApiCallDetails.HasSuccessfulStatusCode)
{
    Console.WriteLine($"Error applying policy to index: {indexSettingsResponse.Body}");
}
else
{
    Console.WriteLine("Policy applied successfully to index.");
}
