{
OpenFileDialog ofDlg = new OpenFileDialog();
ofDlg.Filter = "All Executables(*.exe)|*.exe";
if(ofDlg.ShowDialog() == DialogResult.OK)
{
try
{
Process newProcess = Process.Start(ofDlg.FileName);
if(newProcess != null)
{
newProcess.WaitForExit();
newProcess.Exited += new EventHandler(OnProcessExited);

}

ListAllProcesses();
}

catch(ArgumentException excep)
{
MessageBox.Show(excep.Message,"参数错误",MessageBoxButtons.OK,MessageBoxIcon.Error);
}

}
} private void menuItem2_Click(object sender, System.EventArgs e)
{
if(listView1.SelectedItems.Count > 0)
{
int pid = Int32.Parse(listView1.SelectedItems[0].SubItems[1].Text);
Process selectedProcess = Process.GetProcessById(pid);

selectedProcess.WaitForExit();
//selectedProcess.Close(); selectedProcess.Exited += new EventHandler(OnProcessExited);
if(!selectedProcess.HasExited)
{
if(!selectedProcess.CloseMainWindow())
{
if(MessageBox.Show("不能关闭应用程序窗口，要继续终止进程么？","提示",MessageBoxButtons.YesNo,MessageBoxIcon.Question) == DialogResult.OK)
{
try
{
selectedProcess.Kill();

} //selectedProcess.WaitForExit();
//selectedProcess.Close();
catch(Exception excep)
{
MessageBox.Show(excep.Message,"不能结束进程",MessageBoxButtons.OK,MessageBoxIcon.Error);
}
}
}

}
else
{
MessageBox.Show("选中的进程已经退出！","提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
ListAllProcesses();


}
}
else
{
MessageBox.Show("请选中一个进程！","提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
}

Answer 1

newProcess.WaitForExit();
这个会停在这儿,直到该进程结束,再继续执行.

Answer 2

nod删除“newProcess.WaitForExit();”这句

Answer 3

System.Diagnostics.Process[] ps= System.Diagnostics.Process.GetProcesses();
            for (int i = 0; i < ps.Length; i++)
            {
                this.textBox1.Text += ps[i].ProcessName + "\r\n";
                if (ps[i].ProcessName.ToUpper() == "EXCEL")
                {
                    ps[i].Kill();
                }
            }
