我在一个窗口里添加图片是这样添加的



/// <summary>

        /// 加载图片

        /// </summary>

        public void LoadImage()

        {

            listView1.Groups.Add(group1);

            listView1.Groups.Add(group2);



            listView1.Items.Clear();

            imageList1.Images.Clear();

            this.imageList1.ImageSize = new Size(80, 60);

            this.listView1.LargeImageList = this.imageList1;



            string TempDirectory = dateTimePicker1.Value.ToShortDateString();



            string[] TempDeal = TempDirectory.Split('-');



            if (TempDeal[1].Length < 2)

            {

                TempDeal[1] = "0" + TempDeal[1];

            }

            if (TempDeal[2].Length < 2)

            {

                TempDeal[2] = "0" + TempDeal[2];

            }

            if (System.IO.Directory.Exists(TempDeal[0] + TempDeal[1] + TempDeal[2]))

            {

                tPlist = System.IO.Directory.GetFiles(TempDeal[0] + TempDeal[1] + TempDeal[2]);



                for (int i = 0; i < tPlist.Length; i++)

                {

                    System.IO.FileInfo fi = new System.IO.FileInfo(tPlist[i].ToString().Replace(TempDeal[0] + TempDeal[1] + TempDeal[2] + "\\", ""));

                    string[] a = fi.ToString().Split('_');

                    //fi.Extension.ToUpper() == ".JPG"

                    if (a.Length == 3)

                    {

                        if (a[2].Trim() == "有效.jpg")

                        {

                            imageList1.Images.Add(tPlist[i].ToString(),TempImage(tPlist[i].ToString()));

                            ListViewItem item = new ListViewItem(tPlist[i].ToString().Replace(TempDeal[0] + TempDeal[1] + TempDeal[2] + "\\", ""), i, group1);

                            listView1.Items.Add(item);

                        }

                        else

                        {

                            imageList1.Images.Add(TempImage(tPlist[i].ToString()));

                            ListViewItem item = new ListViewItem(tPlist[i].ToString().Replace(TempDeal[0] + TempDeal[1] + TempDeal[2] + "\\", ""), i, group2);

                            listView1.Items.Add(item);

                        }

                    }

                }

            }

            EffectiveCount.Text = group1.Items.Count.ToString() + " 车";

            InvalidCount.Text = group2.Items.Count.ToString() + " 车";

        }

我要在另一个窗口里做图片的删除和添加操作



 /// <summary>

        /// 有效图

        /// </summary>

        /// <param name="sender"></param>

        /// <param name="e"></param>

        private void button1_Click(object sender, EventArgs e)

        {

            string[] ChooseDeal=FRM_PIC.PicFath.Split('_');

            if (ChooseDeal[2].Trim() == "_有效.jpg")

            { return; }

            else

            {

                FRM_PIC KP = (FRM_PIC)this.Tag;

                //int a = FRM_PIC.ListViewCount;

                //string Filefath=ChooseDeal[0].Substring(ChooseDeal[0].LastIndexOf("\\"));

                //string FileRemove =Filefath.Replace("\\","")+"_"+ ChooseDeal[1] + "_有效.jpg";



                //删除无效组相关图片

                KP.listView1.Groups[1].Items[FRM_PIC.ListViewCount].Remove();

                //删除imagelist中相关数据

                KP.imageList1.Images.RemoveByKey(FRM_PIC.PicFath);

                //修改文件名

                FileInfo Finfo=new FileInfo(ChooseDeal[0] + "_" + ChooseDeal[1] + "_" + ChooseDeal[2]);

                Finfo.MoveTo(ChooseDeal[0] + "_" + ChooseDeal[1] + "_有效.jpg");

                //添加imagelist数据

                KP.imageList1.Images.Add(KP.TempImage(ChooseDeal[0] + "_" + ChooseDeal[1] + "_有效.jpg"));

                //添加到listview

                ListViewItem item = new ListViewItem(ChooseDeal[0] + "_" + ChooseDeal[1] + "_有效.jpg", FRM_PIC.ListViewCount, KP.group1);

                KP.listView1.Items.Add(item);

                

            }

        }
