實現

新建一個窗體頁面，然后設計頁面布局如下

?

選擇圖片按鈕點擊事件中

private void toolStripButton3_Click(object sender, EventArgs e)//選擇轉換文件的按鈕{if (openFileDialog1.ShowDialog() == DialogResult.OK)??????? //判斷是否選擇文件{listView1.Items.Clear();?????????????????????????????? //清空listView1string[] info = new string[7];????????????????????????? //存儲每一行數據FileInfo fi;??????????????????????????????????????????? //創建一個FileInfo對象，用于獲取圖片信息path1 = openFileDialog1.FileNames;????????????????????? //獲取選擇的圖片集合for (int i = 0; i < path1.Length; i++)????????????????? //讀取集合中的內容{//獲取圖片名稱string ImgName = path1[i].Substring(path1[i].LastIndexOf("\\") + 1, path1[i].Length - path1[i].LastIndexOf("\\") - 1);//獲取圖片類型string ImgType = ImgName.Substring(ImgName.LastIndexOf(".") + 1, ImgName.Length - ImgName.LastIndexOf(".") - 1);fi = new FileInfo(path1[i].ToString());???????????? //實例化FileInfo對象//將每一行數據第一個位置的圖標添加到imageList1中imageList1.Images.Add(ImgName,Properties.Resources.圖標__23_);info[1] = ImgName;????????????????????? //圖片名稱info[2] = ImgType;????????????????????? //圖片類型info[3] = fi.LastWriteTime.ToShortDateString();//圖片最后修改日期info[4] = path1[i].ToString();????????????????? //圖片位置info[5] = (fi.Length/1024)+"KB";??????????????? //圖片大小info[6] = "未轉換";??????????????????????????????? //圖片狀態ListViewItem lvi = new ListViewItem(info, ImgName);? //實例化ListViewItem對象listView1.Items.Add(lvi);????????????????????????????? //將信息添加到listView1控件中}tsslFileNum.Text = "當前共有" + path1.Length.ToString() + "個文件";//狀態欄中顯示圖片數量}}

選擇圖片保存位置按鈕點擊事件

private void toolStripButton4_Click(object sender, EventArgs e)//選擇保存路徑按鈕{if (folderBrowserDialog1.ShowDialog() == DialogResult.OK)?? //判斷是否選擇保存路徑{path2 = folderBrowserDialog1.SelectedPath;????????????? //獲取保存路徑}}

開始轉換按鈕點擊事件

private void toolStripButton1_Click(object sender, EventArgs e){if (path1 == null)????????????????????????????????????????????? //判斷是否選擇圖片{MessageBox.Show("請選擇圖片！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);}else{if (path2.Length == 0)????????????????????????????????????? //判斷是否選擇保存位置{MessageBox.Show("請選擇保存位置！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);}else{flags = 1;????????????????????????????????????????????? //初始化flags變量為1，用于計算進度toolStrip1.Enabled = false;???????????????????????????? //當轉換開始時，禁用工具欄int flag = tscbType.SelectedIndex;????????????????????? //判斷將圖片轉換為何種格式switch (flag)?????????????????????????????????????????? //根據不同的格式進行轉換{case 0:Imgtype1 = 0;?????????????????????????????????? //如果選擇第一項則轉換為BMP格式td = new Thread(new ThreadStart(ConvertImage)); //通過線程調用ConvertImage方法進行轉換td.Start();break;case 1:???????????????????????????????????????????? //如果選擇第二項則轉換為JPG格式Imgtype1 = 1;td = new Thread(new ThreadStart(ConvertImage));//通過線程調用ConvertImage方法進行轉換td.Start();break;case 2:??????????????????????????????????????????? //如果選擇第三項則轉換為PNG格式Imgtype1 = 2;td = new Thread(new ThreadStart(ConvertImage));//通過線程調用ConvertImage方法進行轉換td.Start();break;case 3:???????????????????????????????????????????? //如果選擇第四項則轉換為GIF格式Imgtype1 = 3;td = new Thread(new ThreadStart(ConvertImage));//通過線程調用ConvertImage方法進行轉換td.Start();break;default: td.Abort(); break;}}}}
