RemoteAgent クラス
更新 : 2007 年 11 月
デバイスにデバイス エージェント アプリケーションを配置し、デスクトップ コンピュータとスマート デバイスの間でデータを交換するために使用します。
名前空間 : Microsoft.SmartDevice.Connectivity
アセンブリ : Microsoft.SmartDevice.Connectivity (Microsoft.SmartDevice.Connectivity.dll 内)
構文
'宣言
Public Class RemoteAgent
'使用
Dim instance As RemoteAgent
public class RemoteAgent
public ref class RemoteAgent
public class RemoteAgent
解説
インスタンスを取得するには、Device.GetRemoteAgent メソッドを使用します。
このクラスは、データを交換したり、FileDeployer、RemoteProcess、および Device では利用できないカスタム タスクを実行したりするデバイス エージェントを配置するために使用します。詳細については、「スマート デバイス接続 API を使用したデバイスの制御」を参照してください。
