Question

i want to rename a folder/file on runtime in my window explorer when ever i click on the folder…
i know so far that file.move is used to rename but how to enter file name on runtime?

 private void renameToolStripMenuItem_Click(object sender, EventArgs e)
{
    try
    {
        string DestinationFolder = ListviewCurrentFolderPath;
        string CurrentName = DestinationFolder + "FileName";//in filename i want to edit value on run time

        if (Directory.Exists(DestinationFolder))
        {

           // Directory.Move( Path.Combine(new string[] {              DestinationFolder,Path.GetFileName(file) }));
            File.Move( Path.Combine(new string[] { DestinationFolder, CurrentName }));
            PopulateListView(DestinationFolder);

        }
    }
    catch (IOException ios)
    {
        MessageBox.Show(ios.ToString());

    }
}

I guess you mean with ‘rename at runtime’, to rename the label of the listview item which affects in renaming the folder…

So, first of all you should look at

1. ListView.LabelEdit – to enable the ‘renaming’
2. ListView.BeforeLabelEdit
3. ListView.AfterLabelEdit

I hope this little sample helps you to get the right way 🙂

    using System;
    using System.IO;
    using System.Windows.Forms;

    namespace WindowsFormsApplication6
    {
        public partial class Form1 : Form
        {
            private string destinationFolder;
            private ListView listView1;

            public Form1()
            {
                // Set destinationFolder to MyDocuments - for test
                this.destinationFolder = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

                InitializeComponent();

                this.listView1.Clear();
                foreach (var dir in Directory.GetDirectories(destinationFolder))
                {
                    this.listView1.Items.Add(new ListViewItem() { Name = dir, Text = Path.GetFileName(dir) });
                }

            }

            private void SetListViewItemName(int index, string name)
            {
                if (this.listView1.Items.Count < index)
                {
                    this.listView1.Items[index].Name = name;
                }
            }

            private string GetListViewItemText(int index)
            {
                if (this.listView1.Items.Count < index)
                {
                    return this.listView1.Items[index].Text;
                }
                else
                {
                    return String.Empty;
                }
            }

            private void listView1_AfterLabelEdit(object sender, LabelEditEventArgs e)
            {
                try
                {
                    string itemText = GetListViewItemText(e.Item);
                    string sourceDirName = Path.Combine(new string[] { this.destinationFolder, itemText });
                    string destDirName = Path.Combine(new string[] { this.destinationFolder, e.Label });

                    // Rename the old directory.
                    Directory.Move(sourceDirName, destDirName);
                    SetListViewItemName(e.Item, destDirName);
                }
                catch (Exception ex)
                {
                    // Error occured, cancel edit.
                    // Empty text, cancel edit.
                    // There are few more things to check: max pathlength, invalid chars etc.
                    e.CancelEdit = true;
                }
            }

            private void InitializeComponent()
            {
                this.listView1 = new System.Windows.Forms.ListView();
                this.SuspendLayout();
                // 
                // listView1
                // 
                this.listView1.Dock = System.Windows.Forms.DockStyle.Fill;
                this.listView1.LabelEdit = true;
                this.listView1.Location = new System.Drawing.Point(0, 0);
                this.listView1.Name = "listView1";
                this.listView1.Size = new System.Drawing.Size(284, 262);
                this.listView1.TabIndex = 0;
                this.listView1.UseCompatibleStateImageBehavior = false;
                this.listView1.View = System.Windows.Forms.View.List;
                this.listView1.AfterLabelEdit += new System.Windows.Forms.LabelEditEventHandler(this.listView1_AfterLabelEdit);
                //this.listView1.BeforeLabelEdit += new System.Windows.Forms.LabelEditEventHandler(this.listView1_BeforeLabelEdit);
                // 
                // Form1
                // 
                this.ClientSize = new System.Drawing.Size(284, 262);
                this.Controls.Add(this.listView1);
                this.Name = "Form1";
                this.ResumeLayout(false);

            }
        }
    }
