Solution 1

Specify runat="server" on all asp.net controls to access it from form.controls.
In the class System.Web.UI.HTMLControl, the attribute is not required.
However, in the class System.Web.UI.WebControl the attribute is required.

Useful info.
I corrected a couple of spelling mistakes, in case you were wondering.

The basicic heirachy of controls on a page (which uses MasterPages) is MasterPage then HtmlForm then ContentPlaceHolder and then finally will come all the labels, textboxes, and whatever other controls you seek (note that if these controls contain children of their own, like a GridView, you will need to loop through that control to get all the included controls in it).

foreach (Control masterControl in Page.Controls)
{
if (masterControl is MasterPage)
{
foreach (Control formControl in masterControl.Controls)
{
if (formControl is System.Web.UI.HtmlControls.HtmlForm)
{
foreach (Control contentControl in formControl.Controls)
{
if (contentControl is ContentPlaceHolder)
{
foreach (Control childControl in contentControl.Controls)
{

}
}
}
}
}
}
}

For a specific control use this

if (childControl is Label)
{
Label newLabel = (Label)childControl;
newLabel.Text = "You found me!"
}
