InstanceDataCollection.CopyTo(InstanceData[], Int32) 方法

定义

命名空间:

System.Diagnostics

程序集:

System.Diagnostics.PerformanceCounter.dll

包:

System.Diagnostics.PerformanceCounter v8.0.0

Source:

InstanceDataCollection.cs

将集合中的项复制到指定一维数组中的指定索引处。

public:
 void CopyTo(cli::array <System::Diagnostics::InstanceData ^> ^ instances, int index);

public void CopyTo (System.Diagnostics.InstanceData[] instances, int index);

override this.CopyTo : System.Diagnostics.InstanceData[] * int -> unit

Public Sub CopyTo (instances As InstanceData(), index As Integer)

参数

instances

InstanceData[]

一维 Array，它是从集合所复制值的目标位置。

index

Int32

添加新实例的从零开始的索引值。

示例

下面的代码示例使用 CopyTo 方法将 转换为 InstanceDataCollection 对象的数组 InstanceData 。 数组中每个元素的 和 Sample 属性的值InstanceName将传递给函数以供进一步处理。

// Display the contents of an InstanceDataCollection.
public static void ProcessInstanceDataCollection(InstanceDataCollection idCol)
{

    InstanceData[] instDataArray = new InstanceData[idCol.Count];

    Console.WriteLine("  InstanceDataCollection for \"{0}\" " +
        "has {1} elements.", idCol.CounterName, idCol.Count);

    // Copy and process the InstanceData array.
    idCol.CopyTo(instDataArray, 0);

    int idX;
    for(idX=0; idX<instDataArray.Length; idX++)
    {
        ProcessInstanceDataObject(instDataArray[idX].InstanceName, instDataArray[idX].Sample);
    }
}

' Display the contents of an InstanceDataCollection.
Sub ProcessInstanceDataCollection(ByVal idCol As InstanceDataCollection)

    Dim instDataArray(idCol.Count - 1) As InstanceData

    Console.WriteLine("  InstanceDataCollection for ""{0}"" " & _
        "has {1} elements.", idCol.CounterName, idCol.Count)

    ' Copy and process the InstanceData array.
    idCol.CopyTo(instDataArray, 0)

    Dim idX As Integer
    For idX = 0 To instDataArray.Length - 1
        ProcessInstanceDataObject(instDataArray(idX).InstanceName, _
            instDataArray(idX).Sample)
    Next idX
End Sub
