c# 创建Excel com加载项图片对象批量操作
技术含量较低，主要是通过VBA代码转换成c#代码而来，从而实现图片批量插入、删除、另存为的批量操作，增加文档使用的通用性。
插件主要界面如下：
主要代码如下：
1 private void button8_Click(object sender, RibbonControlEventArgs e) 2 { 3 if (checkBox4.Checked == true) 4 { 5 覆盖图片名称插入(); 6 } 7 else 8 if (checkBox4.Checked == false) 9 { 10 excelapp = Globals.ThisAddIn.Application; 11 excel.Worksheet wst = Globals.ThisAddIn.Application.ActiveWorkbook.ActiveSheet; 12 excel.Range inrow = excelapp.InputBox("选择单元格[行]", Type: 8); 13 excel.Range incol = excelapp.InputBox("选择单元格[列]", Type: 8); 14 excel.Range oucol = excelapp.InputBox("选择单元格[列]", Type: 8); 15 int in_row = inrow.Row; 16 int in_col = incol.Column; 17 int ou_col = oucol.Column; 18 float PicLeft, PicTop, PicWidth, PicHeight; 19 int n = wst.Cells[incol.Rows.Count, in_col].End(3).Row; 20 MessageBox.Show("共：" + n.ToString() + "张图片需要插入"); 21 for (int i = 1; i < n + 1; i++) 22 { 23 if (incol.Columns.Count > 1 || inrow.Rows.Count > 1 || oucol.Columns.Count > 1) 24 { 25 MessageBox.Show("所有的选择：只能为1行或者1列"); 26 break; 27 } 28 string str = Convert.ToString(wst.Cells[i, in_col].Value2); 29 if (str == null || str == string.Empty) 30 { 31 continue; 32 } 33 wst.Cells[i, ou_col].RowHeight = editBox2.Text; 34 wst.Cells[i, ou_col].ColumnWidth = editBox1.Text; 35 string filename = Settings.Default.图片插入文件夹路径 + "\\" + wst.Cells[i, in_col].Value2; 36 PicLeft = Convert.ToSingle(wst.Cells[i, ou_col].Left); 37 PicTop = Convert.ToSingle(wst.Cells[i, ou_col].Top); 38 PicWidth = Convert.ToSingle(wst.Cells[i, ou_col].Width); 39 PicHeight = Convert.ToSingle(wst.Cells[i, ou_col].Height); 40 if (checkBox2.Checked == true) 41 { 42 wst.Shapes.AddPicture(filename, MsoTriState.msoFalse, MsoTriState.msoTrue, PicLeft, PicTop, -1, -1); 43 float r; 44 foreach (excel.Shape shp in wst.Shapes) 45 { 46 if (shp.Type == MsoShapeType.msoPicture) 47 { 48 float rh = PicHeight / shp.Height; 49 float rw = PicWidth / shp.Width; 50 if (rw > rh) 51 { 52 r = rh; 53 } 54 else 55 { 56 r = rw; 57 } 58 //shp.Left = PicL; 59 //shp.Top = PicT; 60 shp.ScaleWidth(r, MsoTriState.msoFalse, MsoScaleFrom.msoScaleFromTopLeft); 61 } 62 } 63 } 64 else 65 { 66 wst.Shapes.AddPicture(filename, MsoTriState.msoFalse, MsoTriState.msoTrue, PicLeft, PicTop, PicWidth, PicHeight); 67 } 68 } 69 if (checkBox1.Checked == true) 70 { 71 跟随单元格(); 72 } 73 else 74 { 75 不随单元格(); 76 } 77 } 78 }
