C#结束Excel进程

结束所有的Excel进程：

public void 结束Excel进程()
        {
            Process[] processes = Process.GetProcesses();
            foreach (Process p in processes)
            {
                if (p.ProcessName.Equals("EXCEL"))
                {
                    p.Kill();
                    p.Dispose();
                    p.Close();
                }
            }
        }

结束单个线程：

ArrayList FirstTraversalId = new ArrayList();

    //第一次遍历所有线程
    public void FirstTraversal()
    {
        Process[] processes = Process.GetProcesses();//获取所有的进程
        foreach (Process FirstPro in processes)
        {
            if (FirstPro.ProcessName.Equals("EXCEL"))
            {
                FirstTraversalId.Add(FirstPro.Id);//
            }
        }
    }

    //第二次遍历所有线程
    public void TwoTraversal()
    {       
        Process[] processes = Process.GetProcesses();//获取所有的进程
        foreach (Process TwoPro in processes)
        {
            if (TwoPro.ProcessName.Equals("EXCEL"))
            {               
                foreach (int i in FirstTraversalId)
                {
                    if (i != TwoPro.Id)
                    {
                        TwoPro.Kill();
                        TwoPro.Dispose();
                        TwoPro.Close();
                    }                
                }
            }
        }
    }
