TreeView.PathSeparator 属性

定义

命名空间:

System.Windows.Forms

程序集:

System.Windows.Forms.dll

获取或设置树节点路径所使用的分隔符串。

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

属性值

String

树节点 FullPath 属性所使用的分隔符串。 默认值为反斜杠字符 (\) 。

示例

下面的代码示例设置 PathSeparator a TreeView 属性，并显示包含在 TreeNodeCollection 其中的 SelectedNode子树节点数。 树视图控件中子树节点到树节点总数的百分比也会显示。 此示例要求你有一个具有一Button个Form控件，一个TreeView具有TreeNodeCollection多个TreeNode对象的控件 (最好具有三个或更多个级别) 。

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

注解

树节点路径由一组由分隔符字符串分隔的 PathSeparator 树节点标签组成。 标签范围从根树节点到所需的树节点。
