deviceClassId é nulo.

deviceClassId é uma cadeia de caracteres vazia e era esperado que não estivesse vazio.

O serviço retornou um código de status sem êxito.

Exemplos

Este exemplo mostra como chamar GetDeviceClass com os parâmetros necessários e analisar o resultado.

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

Response response = client.GetDeviceClass("<deviceClassId>");

JsonElement result = JsonDocument.Parse(response.ContentStream).RootElement;
Console.WriteLine(result.GetProperty("deviceClassId").ToString());
Console.WriteLine(result.GetProperty("friendlyName").ToString());
Console.WriteLine(result.GetProperty("deviceClassProperties").GetProperty("contractModel").GetProperty("id").ToString());
Console.WriteLine(result.GetProperty("deviceClassProperties").GetProperty("contractModel").GetProperty("name").ToString());
Console.WriteLine(result.GetProperty("deviceClassProperties").GetProperty("compatProperties").GetProperty("<test>").ToString());
Console.WriteLine(result.GetProperty("bestCompatibleUpdate").GetProperty("updateId").GetProperty("provider").ToString());
Console.WriteLine(result.GetProperty("bestCompatibleUpdate").GetProperty("updateId").GetProperty("name").ToString());
Console.WriteLine(result.GetProperty("bestCompatibleUpdate").GetProperty("updateId").GetProperty("version").ToString());
Console.WriteLine(result.GetProperty("bestCompatibleUpdate").GetProperty("description").ToString());
Console.WriteLine(result.GetProperty("bestCompatibleUpdate").GetProperty("friendlyName").ToString());

Corpo da resposta:

Esquema para DeviceClass:

{
              deviceClassId: string, # Required. The device class identifier. This is generated from the model Id and the compat properties reported by the device update agent in the Device Update PnP interface in IoT Hub. It is a hex-encoded SHA1 hash.
              friendlyName: string, # Optional. The device class friendly name. This can be updated by callers after the device class has been automatically created.
              deviceClassProperties: {
                contractModel: {
                  id: string, # Required. The Device Update agent contract model Id of the device class. This is also used to calculate the device class Id.
                  name: string, # Required. The Device Update agent contract model name of the device class. Intended to be a more readable form of the contract model Id.
                }, # Optional. The Device Update agent contract model.
                compatProperties: Dictionary<string, string>, # Required. The compat properties of the device class. This object can be thought of as a set of key-value pairs where the key is the name of the compatibility property and the value is the value of the compatibility property. There will always be at least 1 compat property
              }, # Required. The device class properties that are used to calculate the device class Id
              bestCompatibleUpdate: {
                updateId: {
                  provider: string, # Required. Update provider.
                  name: string, # Required. Update name.
                  version: string, # Required. Update version.
                }, # Required. Update identifier.
                description: string, # Optional. Update description.
                friendlyName: string, # Optional. Friendly update name.
              }, # Optional. Update that is the highest version compatible with this device class.
            }
