TreeView.PathSeparator TreeView.PathSeparator TreeView.PathSeparator TreeView.PathSeparator Property

定義

取得或設定樹狀節點路徑使用的分隔符號字串。Gets or sets the delimiter string that the tree node path uses.

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

樹狀節點 FullPath 屬性使用的分隔符號字串。The delimiter string that the tree node FullPath property uses. 預設值為反斜線字元(\)。The default is the backslash character (\).

範例

下列程式碼範例會設定PathSeparator的屬性TreeView ,並顯示SelectedNode包含在中TreeNodeCollection的子樹狀節點的數目。The following code example sets the PathSeparator property of a TreeView and displays the number of child tree nodes that is contained in the TreeNodeCollection of the SelectedNode. 同時也會顯示樹狀檢視控制項中子樹狀節點與樹狀結構節點總數的百分比。The percentage of child tree node to total tree nodes in the tree view control is also displayed. 這個範例需要Form您具有Button具有的, TreeNodeCollection以及TreeView具有具有數個TreeNode物件之的控制項(最好是三個以上的層級)。This example requires that you have a Form with a Button, and a TreeView control with a TreeNodeCollection that has several TreeNode objects (preferably with three or more levels).

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PathSeparator分隔符號字串分隔的樹狀節點標籤所組成。The tree node path consists of a set of tree node labels separated by the PathSeparator delimiter strings. 標籤的範圍從根樹狀結構節點到您想要的樹狀節點。The labels range from the root tree node to the tree node that you want.
