做项目时收集的一些资料,分享一下,希望对大家有用
常用的一些操作
range.NumberFormatLocal = "@"; //设置单元格格式为文本
- range = (Range)worksheet.get_Range("A1", "E1"); //获取Excel多个单元格区域:本例做为Excel表头
- range.Merge(0); //单元格合并动作
- worksheet.Cells[1, 1] = "Excel单元格赋值"; //Excel单元格赋值
- range.Font.Size = 15; //设置字体大小
- range.Font.Underline=true; //设置字体是否有下划线
- range.Font.Name="黑体"; 设置字体的种类
- range.HorizontalAlignment=XlHAlign.xlHAlignCenter; //设置字体在单元格内的对其方式
- range.ColumnWidth=15; //设置单元格的宽度
- range.Cells.Interior.Color=System.Drawing.Color.FromArgb(255,204,153).ToArgb(); //设置单元格的背景色

- range.BorderAround(XlLineStyle.xlContinuous,XlBorderWeight.xlThick,XlColorIndex.xlColorIndexAutomatic,System.Drawing.Color.Black.ToArgb()); //给单元格加边框
- range.Borders.get_Item(Microsoft.Office.Interop.Excel.XlBordersIndex.xlEdgeTop).LineStyle = Microsoft.Office.Interop.Excel.XlLineStyle.xlLineStyleNone; //设置单元格上边框为无边框

- Range.Font.Color=clBlue; //字体颜色
- xlsApp.DisplayAlerts=false; //保存Excel的时候,不弹出是否保存的窗口直接进行保存

在Excel中设置背景字体及其它颜色的时候用的都是索引
如: xSt.get_Range(excel.Cells[2, i], excel.Cells[2, i]).Font.ColorIndex = 5
特此提供一个对应的Excel颜色索引图例

还有就是可能是大家最关心的Excel.exe的问题了,分享我们项目中的几个释放进程的方法,希望对大家有用,都是绝对好使的
方法1
- #region 释放excel.exe
- [System.Runtime.InteropServices.DllImport("user32.dll", SetLastError = true)]
- static extern int GetWindowThreadProcessId(IntPtr hWnd, out int lpdwProcessId);
- public void KillSpecialExcel()
- {
- try
- {
- if (excel != null)
- {
- int lpdwProcessId;
- GetWindowThreadProcessId(new IntPtr(excel.Hwnd), out lpdwProcessId);
- System.Diagnostics.Process.GetProcessById(lpdwProcessId).Kill();
- }
- }
- catch (Exception ex)
- {
- Console.WriteLine("Delete Excel Process Error:" + ex.Message);
- }
- }
- #endregion
方法2
- #region KillAllExcel
- public bool KillAllExcel()
- {
- try
- {
- if (m_objExcel != null)
- {
- m_objExcel.Quit();
- System.Runtime.InteropServices.Marshal.ReleaseComObject(m_objExcel);
- //释放COM组件,其实就是将其引用计数减1
- //System.Diagnostics.Process theProc;
- foreach (System.Diagnostics.Process theProc in System.Diagnostics.Process.GetProcessesByName("EXCEL"))
- {
- //先关闭图形窗口。如果关闭失败...有的时候在状态里看不到图形窗口的excel了,
- //但是在进程里仍然有EXCEL.EXE的进程存在,那么就需要杀掉它
- if (theProc.CloseMainWindow() == false)
- {
- theProc.Kill();
- }
- }
- m_objExcel = null;
- return true;
- }
- }
- catch
- {
- return false;
- }
- return true;
- }
- #endregion
