c# - 通过单击重命名文件/文件夹（在使用列表视图的自制窗口资源管理器中）

Question

当我单击文件夹时，我想在运行时在我的窗口资源管理器中重命名文件夹/文件...到目前为止，我知道 file.move 用于重命名，但如何在运行时输入文件名？

 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());

    }
}

Answer 1

可能您需要使用SaveFileDialog Class。您可以使用DestinationFolderFileDialog.InitialDirectory属性。

Answer 2

我猜你的意思是“在运行时重命名”，重命名影响重命名文件夹的列表视图项目的标签......

所以，首先你应该看看

1. ListView.LabelEdit - 启用“重命名”
2. ListView.BeforeLabel编辑
3. ListView.AfterLabel编辑

我希望这个小样本可以帮助您找到正确的方法:)

    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;

                {
                    return String.Empty;
                }
            }

            private void listView1_AfterLabelEdit(object sender, LabelEditEventArgs e)
            {
                try

                    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);
                //

                this.ClientSize = new System.Drawing.Size(284, 262);
                this.Controls.Add(this.listView1);
                this.Name = "Form1";
                this.ResumeLayout(false);

            }
        }
