c#语言实现对电脑文件夹的批量改名，选定改名

 

 //当点击文件改名选择文件夹的时候

        string s;

        private void 选择文件夹ToolStripMenuItem_Click(object sender, EventArgs e)

        {

            textBox1.Clear();

            textBox2.Clear();

            comboBox1.Text = null;

            listView1.Clear();

            DialogResult isok = folderBrowserDialog1.ShowDialog();   //打开文件夹

            if (isok == DialogResult.OK)

            {

                s = folderBrowserDialog1.SelectedPath;    //选择文件夹名

                comboBox1.Text = s;                      //把文件名显示一下

                comboBox1.Items.Add(s);

            }



        }

        //当点击文件列举的时候

        List<string> al = new List<string>();

        private void 文件列举ToolStripMenuItem1_Click(object sender, EventArgs e)

        {

             

            foreach (string file in Directory.GetFiles(comboBox1.Text))  //用Directory.getfiles方法读取文件夹里文件名，遍历出来然后放在file这个变量里

            {

                al.Add(file);

            }

            listView1.Columns.Clear();

            listView1.Columns.Add("文件名",400);

            listView1.Items.Clear();

            listView1.GridLines = true;

            for (int i = 0; i < al.Count; i++)

            {

                listView1.Items.Add(al[i].ToString());

            }



        }

       

        //修改一个文件夹里全部的文件名

        private void 批量改名ToolStripMenuItem_Click(object sender, EventArgs e)

        {

            for (int i = 0; i < al.Count; i++)

            {

                System.IO.File.Move(al[i].ToString(), al[i].Replace(System.IO.Path.GetFileName(al[i]), textBox1.Text.ToString() + (i + 1).ToString() + System.IO.Path.GetExtension(al[i]).ToString()));



            }

        }

        //修改选中的文件名

        private void 部分改名ToolStripMenuItem_Click(object sender, EventArgs e)

        {

           

            MessageBox.Show(listView1 .SelectedItems .Count.ToString());

            for (int i = 0; i <listView1 .SelectedItems .Count; i++)

            {

                

                System.IO.File.Move(listView1.SelectedItems[i].Text,al[i].Replace(System.IO.Path.GetFileName(al[i]),textBox1.Text .ToString()+(i+1).ToString ()+System.IO .Path .GetExtension(al[i].ToString ())));
