Examples

This sample shows how to call StartLogCollectionAsync with required parameters and request content, and how to parse the result.

var credential = new DefaultAzureCredential();
var endpoint = new Uri("<https://my-service.azure.com>");
var client = new DeviceManagementClient(endpoint, "<instanceId>", credential);

var data = new {
    deviceList = new[] {
        new {
            deviceId = "<deviceId>",
        }
    },
};

Response response = await client.StartLogCollectionAsync("<logCollectionId>", RequestContent.Create(data));

JsonElement result = JsonDocument.Parse(response.ContentStream).RootElement;
Console.WriteLine(result.GetProperty("deviceList")[0].GetProperty("deviceId").ToString());
