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
