protected IotHubServiceClient ();Protected Sub New ()Applies to
IotHubServiceClient(String, IotHubServiceClientOptions)
Create an instance of this class that authenticates service requests using an IoT hub connection string.
public IotHubServiceClient (string connectionString, Microsoft.Azure.Devices.IotHubServiceClientOptions options = default);new Microsoft.Azure.Devices.IotHubServiceClient : string * Microsoft.Azure.Devices.IotHubServiceClientOptions -> Microsoft.Azure.Devices.IotHubServiceClientPublic Sub New (connectionString As String, Optional options As IotHubServiceClientOptions = Nothing)Parameters
- connectionString
- String
The IoT hub connection string.
- options
- IotHubServiceClientOptions
The optional client settings.
Exceptions
Thrown when the provided connection string is null.
Thrown when the provided connection string is empty or whitespace.
Applies to
IotHubServiceClient(String, AzureSasCredential, IotHubServiceClientOptions)
Create an instance of this class that authenticates service requests with a shared access signature provided and refreshed as necessary by the caller.
public IotHubServiceClient (string hostName, Azure.AzureSasCredential credential, Microsoft.Azure.Devices.IotHubServiceClientOptions options = default);new Microsoft.Azure.Devices.IotHubServiceClient : string * Azure.AzureSasCredential * Microsoft.Azure.Devices.IotHubServiceClientOptions -> Microsoft.Azure.Devices.IotHubServiceClientPublic Sub New (hostName As String, credential As AzureSasCredential, Optional options As IotHubServiceClientOptions = Nothing)Parameters
- hostName
- String
IoT hub host name. For instance: "my-iot-hub.azure-devices.net".
- credential
- AzureSasCredential
Credential that generates a SAS token to authenticate with IoT hub. See AzureSasCredential.
- options
- IotHubServiceClientOptions
The optional client settings.
Exceptions
Thrown when the provided hostName or credential is null.
Thrown when the provided hostName is empty or whitespace.
Remarks
Users may wish to build their own shared access signature (SAS) tokens rather than give the shared key to the SDK and let it manage signing and renewal. The AzureSasCredential object gives the SDK access to the SAS token, while the caller can update it as necessary using the Update(String) method.
Applies to
IotHubServiceClient(String, TokenCredential, IotHubServiceClientOptions)
Create an instance of this class that authenticates service requests using an identity in Azure Active Directory (AAD).
public IotHubServiceClient (string hostName, Azure.Core.TokenCredential credential, Microsoft.Azure.Devices.IotHubServiceClientOptions options = default);new Microsoft.Azure.Devices.IotHubServiceClient : string * Azure.Core.TokenCredential * Microsoft.Azure.Devices.IotHubServiceClientOptions -> Microsoft.Azure.Devices.IotHubServiceClientPublic Sub New (hostName As String, credential As TokenCredential, Optional options As IotHubServiceClientOptions = Nothing)Parameters
- hostName
- String
IoT hub host name. For instance: "my-iot-hub.azure-devices.net".
- credential
- TokenCredential
Azure Active Directory (AAD) credentials to authenticate with IoT hub.
- options
- IotHubServiceClientOptions
The optional client settings.
Exceptions
Thrown when the provided hostName or credential is null.
Thrown when the provided hostName is empty or whitespace.
Remarks
