推荐答案

处理TreeView.NodeMouseClick事件并使用e.Node属性选择节点. br/> 然后，您可以使用File.ReadAllLines读取文件并设置TextBox.Lines属性.

Handle the TreeView.NodeMouseClick event and use the e.Node property to select the node.
You can then read the file using File.ReadAllLines and set the TextBox.Lines property.

要对节点单击做出反应，可以使用 RichTextBox.LoadFile方法(字符串) [ ^ ]填充富文本框.

加法:

要标识该节点，您可以使用例如文本 [^ ]或标记 [ TreeNodeMouseClickEventArgs类 [

To react on an node click, you can use the TreeView.NodeMouseClick Event[^].

So in that event you can check which node was clicked and then if the node is the correct one you can use the RichTextBox.LoadFile Method (String)[^] to fill the rich text box.

Addition:

To identify the node, you can use for example the Text[^] or Tag[^] properties.

The event arguments of the NodeMouseClick include the node that was selected. See: TreeNodeMouseClickEventArgs Class[^]

Addition 2:
Instead of presuming that the file isn''t found check what the exception says. So change the code to:

private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
       {
           try
           {
               // Look for a  spacific text in the node
               if (e.Node.Text.Contains("Desert Quest"))
               {
                   string DesertFile = "Z:\\Tibia Tool\\Quests\\DesertQuest.txt";
                   rchQuests.LoadFile(DesertFile, RichTextBoxStreamType.PlainText);
               }
           }
           } catch (System.IO.FileNotFoundException) {
              MessageBox.Show("File not found");
           }
           catch (System.Exception exception)
           {
              MessageBox.Show(exception.Message);
           }
       }

如果异常是未找到文件以外的其他东西，那也将为您提供确切的详细信息.

That would give you the exact details also if the exception is something else than file not found.

即使您编写"click"，也很可能意味着处理节点选择事件，，TreeView.AfterSelect:
http://msdn.microsoft.com/en-us/library/system.windows.forms.treeview.beforeselect.aspx [ ^ ]，
http://msdn.microsoft.com/en-us/library/system.windows.forms.treeview.afterselect.aspx [ ^ ].

此外，从您的问题还不清楚您是否使用WPF，Forms或其他东西.请始终对其进行标记.这个想法几乎是一样的.

Even though you write "click", most likely you mean handling the node selection events, TreeView.BeforeSelect, TreeView.AfterSelect:
http://msdn.microsoft.com/en-us/library/system.windows.forms.treeview.beforeselect.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.forms.treeview.afterselect.aspx[^].

Besides, from your question it''s not clear if you use WPF, Forms or something else. Please tag it, always. The idea is pretty much the same.
