TreeView.PathSeparator 屬性

定義

取得或設定樹狀節點路徑使用的分隔符號字串。

public:
 property System::String ^ PathSeparator { System::String ^ get(); void set(System::String ^ value); };
public string PathSeparator { get; set; }
member this.PathSeparator : string with get, set
Public Property PathSeparator As String

屬性值

String

樹狀節點 FullPath 屬性使用的分隔符號字串。 預設值為反斜線字元 (\) 。

範例

下列程式碼範例會設定 PathSeparatorTreeView 屬性,並顯示 包含在 的 SelectedNode 子樹狀結構節點 TreeNodeCollection 數目。 也會顯示樹狀檢視控制項中子樹狀節點與樹狀節點總數的百分比。 此範例需要您具有 Form 具有 的 ,以及 TreeView 具有數 TreeNodeButton 物件的 控制項 TreeNodeCollection (,最好搭配三個或多個層級) 。

void myButton_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
{

   // Set the tree view's PathSeparator property.
   myTreeView->PathSeparator = ".";

   // Get the count of the child tree nodes contained in the SelectedNode.
   int myNodeCount = myTreeView->SelectedNode->GetNodeCount( true );
   Decimal myChildPercentage = ((Decimal)myNodeCount / (Decimal)myTreeView->GetNodeCount( true )) * 100;

   // Display the tree node path and the number of child nodes it and the tree view have.
   MessageBox::Show( String::Concat( "The '", myTreeView->SelectedNode->FullPath, "' node has ", myNodeCount, " child nodes.\nThat is ", String::Format( "{0:###.##}", myChildPercentage ), "% of the total tree nodes in the tree view control." ) );
}
private void myButton_Click(object sender, System.EventArgs e)
{
   // Set the tree view's PathSeparator property.
   myTreeView.PathSeparator = ".";

   // Get the count of the child tree nodes contained in the SelectedNode.
   int myNodeCount = myTreeView.SelectedNode.GetNodeCount(true);
   decimal myChildPercentage = ((decimal)myNodeCount/
     (decimal)myTreeView.GetNodeCount(true)) * 100;

   // Display the tree node path and the number of child nodes it and the tree view have.
   MessageBox.Show("The '" + myTreeView.SelectedNode.FullPath + "' node has "
     + myNodeCount.ToString() + " child nodes.\nThat is "
     + string.Format("{0:###.##}", myChildPercentage)
     + "% of the total tree nodes in the tree view control.");
}
Private Sub myButton_Click(ByVal sender As Object, _
  ByVal e As System.EventArgs) Handles myButton.Click
   ' Set the tree view's PathSeparator property.
   myTreeView.PathSeparator = "."

   ' Get the count of the child tree nodes contained in the SelectedNode.
   Dim myNodeCount As Integer = myTreeView.SelectedNode.GetNodeCount(True)
   Dim myChildPercentage As Decimal = CDec(myNodeCount) / _
      CDec(myTreeView.GetNodeCount(True)) * 100

   ' Display the tree node path and the number of child nodes it and the tree view have.
   MessageBox.Show(("The '" + myTreeView.SelectedNode.FullPath + "' node has " _
      + myNodeCount.ToString() + " child nodes." + Microsoft.VisualBasic.ControlChars.Lf _
      + "That is " + String.Format("{0:###.##}", myChildPercentage) _
      + "% of the total tree nodes in the tree view control."))
End Sub

備註

樹狀節點路徑是由一組以分隔符號字串分隔的 PathSeparator 樹狀節點標籤所組成。 標籤的範圍從根樹狀目錄節點到您想要的樹狀節點。
