Process.ToString メソッド

.NET Framework クラス ライブラリ リファレンス

Process.ToString メソッド

プロセス名の書式指定は文字列にします。親コンポーネント型があれば、この型と組み合わせます。

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

Visual Basic (宣言)

Public Overrides Function
 ToString As String

Visual Basic (使用法)

Dim instance As Process
Dim returnValue As String

returnValue = instance.ToString

C#

public override string ToString ()

C++

public:
virtual String^ ToString () override

J#

public String ToString ()

JScript

public override function ToString () : String

戻り値
ベース コンポーネントの ToString の戻り値と組み合わせた ProcessName。

例外

例外の種類	条件
PlatformNotSupportedException	ToString は、Windows 98 ではサポートされていません。

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。
