比如关闭EXCEL进程，如下函数
            /// <summary>
            /// 关闭Excel进程
            /// </summary>


            public void CloseExcel()
            {
                System.Diagnostics.Process myproc= new System.Diagnostics.Process();
                //得到所有打开的进程
                try
                {
                    foreach (Process thisproc in Process.GetProcessesByName("Excel"))
                    {
                        if(!thisproc.CloseMainWindow())
                        {
                            thisproc.Kill();
                        }
                    }
                }
                catch(Exception ex)
                {
                    throw ex;
                }            
            }

就是等不进
