调用下面的方法就可以了,比如:KillProcess("EXCEL");//结束指定进程 private void KillProcess(string processName) { System.Diagnostics.Process myproc = new System.Diagnostics.Process(); //得到所有打开的进程 try { foreach (System.Diagnostics.Process thisproc in System.Diagnostics.Process.GetProcessesByName(processName)) { if (!thisproc.CloseMainWindow()) { thisproc.Kill(); } } } catch (Exception Exc) { this.Text += "杀死" + processName + "失败!\n" + Exc.Message; } }
