Redirect the parent window when inside a frame

One of my project it's website has a frameset setting like the following:

<frameset border="0" frameborder="NO" framespacing="0" rows="110,*">
<frame index="" name="topFrame" noresize="" ome="" scrolling="NO" src="@Url.Action("AgentHeader", "Home")"><frame>
<frame name="main"></frame>
</frameset>

The "main" frame is the major workplace. However, if I set the logout method like the following, only the "main" frame will by redirected to login page. The "topFrame" is still there.

public ActionResult Logout()
{
    .....

    return RedirectToAction("Login", "Home");
}

How to redirect includes the whole page? (The parent window actually)
Here is what I got from the stack overflow and it works for me:

public ActionResult Logout()
{
    .....

    return Content("<html><script>window.top.location.href = 'your url';</script></html>");
}

Please share some other approaches with me if they work in this kind of situation.

Reference: Redirect the entire page from MVC3 Razor iFrame page to a different URL

[C#] Customize the delimiter of CSV when loading it by using Excel.Workbook.Open() (VBA)

I got an old program which can load a csv file and do something. The customer wants to change the delimiter from comma (,) to others like ";", "|", or "-"... etc. Sounds like an easy job. But no, it's not. The approach that uses on opening the csv file is

using Microsoft.Office;
....
xlsApp = new Excel.ApplicationClass();
xlsWBs = xlsApp.Workbooks;
xlsWB = xlsWBs.Open(TempFileName,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing);
