コレクション内での CounterCreationData のインデックスを返します。

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

Visual Basic (宣言)

Public Function IndexOf ( _
    value As CounterCreationData _
) As Integer

Visual Basic (使用法)

Dim instance As CounterCreationDataCollection
Dim value As CounterCreationData
Dim returnValue As Integer

returnValue = instance.IndexOf(value)

public int IndexOf (
    CounterCreationData value
)

C++

public:
int IndexOf (
    CounterCreationData^ value
)

public int IndexOf (
    CounterCreationData value
)

JScript

public function IndexOf (
    value : CounterCreationData
) : int

パラメータ

value: コレクション内でインデックスを判断する CounterCreationData。

戻り値
値がコレクションに存在する場合は、その値の 0 から始まるインデックス。それ以外の場合は -1。
