public virtual System.Threading.Tasks.Task<Azure.Response> GetUpdateAsync (string provider, string name, string version, Azure.ETag? ifNoneMatch = default, Azure.RequestContext context = default);

abstract member GetUpdateAsync : string * string * string * Nullable<Azure.ETag> * Azure.RequestContext -> System.Threading.Tasks.Task<Azure.Response>
override this.GetUpdateAsync : string * string * string * Nullable<Azure.ETag> * Azure.RequestContext -> System.Threading.Tasks.Task<Azure.Response>

Public Overridable Function GetUpdateAsync (provider As String, name As String, version As String, Optional ifNoneMatch As Nullable(Of ETag) = Nothing, Optional context As RequestContext = Nothing) As Task(Of Response)

Parameters

provider: String

Update provider.

name: String

Update name.

version: String

Update version.

ifNoneMatch: Nullable<ETag>

Defines the If-None-Match condition. The operation will be performed only if the ETag on the server does not match this value.

context: RequestContext

The request context, which can override default behaviors of the client pipeline on a per-call basis.

Returns

Task<Response>

Examples

This sample shows how to call GetUpdateAsync with required parameters and parse the result.

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

Response response = await client.GetUpdateAsync("<provider>", "<name>", "<version>");

JsonElement result = JsonDocument.Parse(response.ContentStream).RootElement;
Console.WriteLine(result.GetProperty("updateId").GetProperty("provider").ToString());
Console.WriteLine(result.GetProperty("updateId").GetProperty("name").ToString());
Console.WriteLine(result.GetProperty("updateId").GetProperty("version").ToString());
Console.WriteLine(result.GetProperty("compatibility")[0].GetProperty("<test>").ToString());
Console.WriteLine(result.GetProperty("manifestVersion").ToString());
Console.WriteLine(result.GetProperty("importedDateTime").ToString());
Console.WriteLine(result.GetProperty("createdDateTime").ToString());
