Public ReadOnly Property FullPath As String

屬性值

從根樹狀節點通往目前樹狀節點的路徑。The path from the root tree node to the current tree node.

例外狀況

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 are 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

路徑包含所有樹狀節點的標籤,必須從根樹狀節點開始,才能流覽至此樹狀節點。The path consists of the labels of all the tree nodes that must be navigated to reach this tree node, starting at the root tree node. 節點標籤會以包含此節點PathSeparator TreeView之控制項的屬性中指定的分隔符號分隔。The node labels are separated by the delimiter character specified in the PathSeparator property of the TreeView control that contains this node. 例如,如果名為 "Location" 之樹狀檢視控制項的分隔符號設定為反斜線字元\(),則FullPath屬性值為 "Country\Region\State"。For example, if the delimiter character of the tree view control named "Location" is set to the backslash character, (\), the FullPath property value is "Country\Region\State".
