C#如何结束EXCEL进程

Question

我用using ( Microsoft.InterOp.Office.Excel.ApplicationClass excel = new Microsoft.InterOp.Office.Excel.ApplicationClass())
{
..........代码
}
无法释放Excel进程，按理说using()内的所有对象都会被回收的。

Answer 1

Excel不是托管代码，试试用

#region 结束EXCEL.EXE进程的方法
/// <summary>
/// 结束EXCEL.EXE进程的方法
/// </summary>
/// <param name="m_objExcel">EXCEL对象</param>
[DllImport("user32.dll", SetLastError = true)]
static extern int GetWindowThreadProcessId(IntPtr hWnd, out int lpdwProcessId);

public void KillSpecialExcel(Microsoft.Office.Interop.Excel.Application m_objExcel)
{
try
{
if (m_objExcel != null)
{
int lpdwProcessId;
GetWindowThreadProcessId(new IntPtr(m_objExcel.Hwnd), out lpdwProcessId);

System.Diagnostics.Process.GetProcessById(lpdwProcessId).Kill();
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
#endregion

Answer 2

这个可以删掉
System.Diagnostics.Process[] process=System.Diagnostics.Process.GetProcessesByName("Excel");
foreach (System.Diagnostics.Process p in process)
{
if (!string.IsNullOrEmpty(ProName))
{
try
{
p.Kill();
}
catch { }
}
}
