To display the file contents we need a RichText Box. Now that we have achieved the first objective, let us move on to the next one. When the above code snippet executes, the following images are placed next to the nodes. TreeNode child = new TreeNode(dirinfo.Name,1,2) DirectoryInfo dirinfo in dir.GetDirectories()) TreeNode node = new TreeNode(drv,imagindex,2) įoreach (System.IO. Private void button2_Click( object sender, EventArgs e) Now we need to slightly modify the above code to place the respective images next to the nodes. Now select the 'treeview' control and on the properties tab, select the 'imagelist' property and then select the 'imagelist' from the dropdown list. Now lets see what we have achieved until now.Īnd finally, select an image that will be placed next to the folder when it is opened (selected index will be 2). The above snippet will populate the drives with their respective folders and files. The above function will be called in the following manner, noting the additional 'filldrives' function call. DirectoryInfo info in dir.GetDirectories())įilldrives(child.FullPath, child, level) įoreach (System.IO. Private void filldrives( string drv, TreeNode parent, int level) List of Logical Drives with their Files and Folders Our next step will be to have a function that is able to display the drives along with their related files and folders. The TreeView shows the Drives but it does not show the files and folders contained in them. Still, the display of the Tree View is not as useful as it could be. The above set of commands gets a list of all the available logical drives and shows them in the Tree View control. String drives = Environment.GetLogicalDrives() Now we will expand functionality to allow us to select any available system drive and then to display its folders and files. The below function displays the list of all the folders in the ListBox control.įoreach (System.IO. The above function displays the list of all the files in a ListBox control. DirectoryInfo( 'C:\') įoreach (System.IO. To begin we need to have some functions and code which can retrieve the directory list from a specified drive. If the file is selected from the list, the contents of the file is shown in a TextBox in ReadOnly mode.
