Can someone help me please?

I need to store the values from the textboxes to a string of array.
string[] array = this.Controls.OfType<TextBox>()
.Select(r=> r.Text)
.ToArray();
The above expects the TextBoxes to be on the Form directly, not inside a container, if they are inside multiple containers then you should get all the controls recursively.
Make sure you include using System.Linq;.
If you are using lower frameworks than .Net Framework 3.5. Then you can use a simple foreach loop like:
List<string> list = new List<string>();
foreach(Control c in this.Controls)
{
if(c is TextBox)
list.Add((c as TextBox).Text);
}
(this would work with .Net framework 2.0 onward)

Smart! my alternative solution is to manually create the textboxes in code, instead of using the designer, and then the rest is trivial.

Habib, I am having this error 'System.Windows.Forms.Control.ControlCollection' does not contain a definition for 'OfType'
Habib
@QKWS, make sure you include
using System.Linq; at the top.QKWS
@Habib May I know the assembly reference for System.Linq? I am having this error:The type or namespace name 'Linq' does not exist in the namespace 'System' (are you missing an assembly reference?)
Habib
@QKWS, what is the .Net framework you are using, it is supported from .Net 3.5 onward.

To get all textboxes not only the direct childs of the form (this)
Func<Control, IEnumerable<Control>> allControls = null;
allControls = c => new Control[] { c }.Concat(c.Controls.Cast<Control>().SelectMany(x => allControls(x)));
var all = allControls(this).OfType<TextBox>()
.Select(t => t.Text)
.ToList();
