关于ListView的应用

Question

我想用ListView做一个类似图片浏览器的工具,展示部份已经可以了,但当我选择一个item用listView1.Items.Remove(item);删除其对应项后,再去删本地图片时,提示图片文件正在使用,无法删除,请问要怎样才可以在删除Item后,删除对应的图片文件,谢谢:代码如下:        private void SetListView(string[] ImageName)
        {
            listView1.GridLines = true;
            listView1.FullRowSelect = true;
            listView1.HideSelection = false;
            listView1.HoverSelection = true;
            listView1.MultiSelect = true;            ImageList LargeImageList = new ImageList();
            LargeImageList.ImageSize = new Size(200, 200);
            ImageList SmallImageList = new ImageList();
            SmallImageList.ImageSize = new Size(100, 100);            int i = 0;
            foreach(string imagename in ImageName)
            {
                SmallImageList.Images.Add(Image.FromFile(imagename.Trim()));
                LargeImageList.Images.Add(Image.FromFile(imagename.Trim()));
                ListViewItem lv = new ListViewItem(imagename);
                //lv1.SubItems.Add("001");
                lv.ImageIndex = i;
                listView1.Items.Add(lv);
                i++;
            }
            listView1.LargeImageList = LargeImageList;
            listView1.SmallImageList = SmallImageList;
            listView1.Refresh();
        }        private void button4_Click(object sender, EventArgs e)
        {
            
            SetListView(new string[]{"Alt.PNG","Manicho.PNG"});        }        private void listView1_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            ListViewItem item = listView1.GetItemAt(e.X, e.Y);
            MessageBox.Show(item.Text);            string filename = item.Text.Trim();
            listView1.Items.Remove(item);
            //listView1.Dispose();
            File.Delete(filename);           &&这里出错
        }请大侠指教啊........

Answer 1

不用说错误了，里面代码有问题，Image没有释放造成的SmallImageList.Images.Add(Image.FromFile(imagename.Trim()));
LargeImageList.Images.Add(Image.FromFile(imagename.Trim()));===========》》》》Image temp = Image.FromFile(imagename.Trim());
SmallImageList.Images.Add(Image.FromFile(new Bitmap(temp));
LargeImageList.Images.Add(Image.FromFile(new Bitmap(temp));
temp.Dispose();

Answer 2

Image   image1= new   Bitmap(""); 
image1.Dispose(); 
再删除
或多线程

to mngzilin:
你的方法我试了,不行.
我改动后的代码如下:
        private void SetListView(string[] ImageName)
        {
            listView1.GridLines = true;
            listView1.FullRowSelect = true;
            listView1.HideSelection = false;
            listView1.HoverSelection = true;
            listView1.MultiSelect = true;            ImageList LargeImageList = new ImageList();
            LargeImageList.ImageSize = new Size(200, 200);
            ImageList SmallImageList = new ImageList();
            SmallImageList.ImageSize = new Size(100, 100);            int i = 0;
            foreach(string imageName in ImageName)
            {
                Image tempImage = Image.FromFile(imageName.Trim());
                SmallImageList.Images.Add(tempImage);
                LargeImageList.Images.Add(tempImage);
                tempImage.Dispose();                ListViewItem lv = new ListViewItem(imageName);
                //lv1.SubItems.Add("001");
                lv.ImageIndex = i;
                listView1.Items.Add(lv);
                i++;
            }
            
            listView1.LargeImageList = LargeImageList;   //报错,说参数没效
            listView1.SmallImageList = SmallImageList;
            
            listView1.Refresh();
        }
  listView1.LargeImageList = LargeImageList;
  listView1.SmallImageList = SmallImageList;
  listView1.Refresh();
  }listView1.LargeImageList = LargeImageList;   //时报错,调试发现LargeImageList中没有数据.

Answer 4

你很强，复制都会出问题，丢了红色的部分Image temp = Image.FromFile(imagename.Trim());
SmallImageList.Images.Add(Image.FromFile(new Bitmap(temp));
LargeImageList.Images.Add(Image.FromFile(new Bitmap(temp));
temp.Dispose();
