.NET Framework クラス ライブラリ リファレンス

Process.TotalProcessorTime プロパティ

このプロセスの合計プロセッサ時間を取得します。

名前空間: System.Diagnostics
アセンブリ: System (system.dll 内)
構文

Visual Basic (宣言)

Public ReadOnly Property
 TotalProcessorTime As TimeSpan

Visual Basic (使用法)

Dim instance As Process
Dim value As TimeSpan

value = instance.TotalProcessorTime

C#

public TimeSpan TotalProcessorTime { get; }

C++

public:
property TimeSpan TotalProcessorTime {
    TimeSpan get ();
}

J#

/** @property */
public TimeSpan get_TotalProcessorTime ()

JScript

public function get TotalProcessorTime
 () : TimeSpan

プロパティ値
関連付けられたプロセスが CPU を使用した時間を示す TimeSpan。この値は、UserProcessorTime と PrivilegedProcessorTime の合計です。

例外

例外の種類	条件
PlatformNotSupportedException	プラットフォームが Windows 98 または Windows Millennium Edition (Windows Me) です。このプロパティはサポートされません。

使用例

メモ帳のインスタンスを起動する例を次に示します。この例では、インスタンスの起動後、関連付けられているプロセスのさまざまなプロパティが取得および表示されます。その後、プロセスの終了を検知し、プロセスの終了コードを表示します。
