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
