母版页上的 ASP.NET VB.NET 搜索按钮根据成员身份和当前目录更改目录

Question

Using masterpage, I have an input and button I need to be able to do navigation between the levels. I've tried

HttpContext.Current.Request.PhysicalApplicationPath, and several other HttpContext ideas that do not work to get the current folder directory a user is in. How do I get the current directory a user is in?

For example, I need to know if user is in "level2" directory, or if in "Level3" directory, or if in root directory.

myurl.com/default.aspx
myurl.com/Level2/default.aspx
myurl.com/level2/Level3/default.aspx

If user is in Level3 then
Redirect here..
ElseIf user is in Root directory Then
Redirect here..
ElseIf user is in Level2 directory Then
Redirect here..
End If

Answer 1

Similar to what VDWWD said:

string[] levels = Request.Url.AbsolutePath.Split('/');

If you Split() at the slash mark ('/') , you get 4 segments

myurl.com/level2/Level3/default.aspx
     1      2      3         4

So:

if(levels.Length == 4)
{
    // you're at level 3. the level is the always the length-1.
}

Answer 2

Using the code from the answer above:

Dim levels As String() = Request.Url.AbsolutePath.Split("/"c)
For Each value In Levels
   If value = "Field" Then
      Response.Redirect("~/Field/orders.aspx?OrderNo=" + qSearch.Text)
   ElseIf value = "Manage" Then
      Response.Redirect("~/Manage/orders.aspx?OrderNo=" + qSearch.Text)
   End If
