Public Overridable Function GetDeviceClass (deviceClassId As String, Optional context As RequestContext = Nothing) As Response

Parameter

deviceClassId

String

Geräteklassenbezeichner.

context

RequestContext

Der Anforderungskontext, der das Standardverhalten der Clientpipeline pro Aufruf außer Kraft setzen kann.

Gibt zurück

Response

Die vom Dienst zurückgegebene Antwort. Details zum Antworttextschema finden Sie im Abschnitt Hinweise unten.

Ausnahmen

ArgumentNullException

deviceClassId ist NULL.

ArgumentException

deviceClassId ist eine leere Zeichenfolge und wurde erwartet, dass sie nicht leer ist.

RequestFailedException

Der Dienst hat einen nicht erfolgreichen status Code zurückgegeben.

Beispiele

In diesem Beispiel wird gezeigt, wie Sie GetDeviceClass mit den erforderlichen Parametern aufrufen und das Ergebnis analysieren.

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());

Schema für 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.
            }
